HD 4.40 BT
I bought the Sennheiser HD 4.40 because I decided an extra £50 for the noise cancelling HD 4.50 was a bit overkill. Turns out I was right. If you're mulling over the 4.40's vs the 4.50's get the 4.40's. Ive been using these for a couple of days now commuting on the Tube, watching movies at home and so on. Noise isn't a problem with these the soft ear cups already cut out pretty much all of the noise you need to cut out. They fit very nicely and are reasonably comfortable. In fact the more I break them in the better they're getting. The headband is a little hard, but if you've got thick hair like me thats not a problem. Though, bald guys, you might find the headband a little hard. It is padded and soft but noticeably firm...again this might change over time with use. As for sound quality. The sound quality is excellent as you would expect from Sennheiser but the tone varies according to what you pair these things with. Paired with Arch Linux using an AptX dongle to watch movies using Kodi, the sound profile is punchy, rich, warm and satisfying. Paired with Android (with AptX) the profile seemed a bit flatter (but not overly so) so you may need an EQ if you want to get a more vibrant experience. I use Pi Music player which has a built in EQ and with the tiniest amount of tweaking I got the sound profile just perfect. For comparison sake, if you know what the Bose QC35's sound like then these headphones will sound richer and warmer compared to the cold aggressive tone of Bose (I find Bose headphones to be a bit trebly). Compared to Beats, theres considerably less volume in the bass here, but the bass is still there, its just not blown out, it's absolutely spot on in my opinion. If you're used to something low end like a Kitsound headphone or maybe a Bludio headphone then you'll find more treble here. You'll also notice a more solid Bluetooth reception. The physical controls work perfectly and are in just the right place. The only minor quirk is when adjusting the volume you get a beep for each notch you adjust. Coming from my old headset this was weird but not annoying. Lastly, don't worry about the all plastic build. These are built like a tank. The materials are tough, flexible and pleasant to the touch. They clamp to your face but not too hard. The pressure is well balanced across the cans and the headband. The faux leather cups are soft and forgiving and large enough to get most ears into. If you're an elephant they won't fit. If you're generally considered to be of roughly human size, you'll be fine. I have reasonably large ears and these feel fine to me. Nice and snug. Overall: Rich sound, great build quality, solid reception, brilliant. Excellent value for money and a very solid contender against 'higher end' kit. If you're a Sennheiser fan. These won't disappoint. If you're not, they won't disappoint.

A great sounding and fantastically priced no nonsense headset.
Bought with my own cash money. In a world where every headphone manufacturer and his dog is sticking noise cancelling on their wireless headphones it's refreshing to have a headphone that just offers the basics. This new line from Sennheiser is no exception to the bells and whistles approach as for a little more money you can pick up the HD4.50 which is essentially the same headset as the 4.40 but it adds ANC to the mix. So it's nice at least to have the choice of a 'basic' wireless headset for those who don't really need/want the extras. Now (digression alert!) - I'll admit - I have a love/hate relationship with ANC. I love the silence I get from my Bose QC35 as the ANC is second to none. Take them into the outside world however and it's pointless as the active mics on the outside of any ANC headset (which enable it to process the external ambient noise to counteract it) produce varying degrees of wind noise which negate the benefits of ANC - In my opinion/experience at least. YMMV of course. Now I still use my QC35 but indoors and as a wired headset (as the Bluetooth connection is shockingly unstable - see my review for more info). Mainly for watching TV etc and for reading in silence and the ANC is the best there is. Bar none. Other manufacturers offer slightly worse (i.e. Cheaper) levels of NC which have less external mics and I've found that some of these work pretty well for real world portable use. Beats Studio Wireless is one example. Whilst it's not cheaper (that's Beats for you) the NC is nowhere near as good as the QC35 but conversely it creates a better listening experience as there are hardly any external mics resulting in an exceptionally reduced wind noise factor. But again because of all the bells and whistles you're looking at a 300 quid shell out. So I digress - and it seems this has been a rather long winded way of saying that I've been through virtually every wireless NC headset out there and found 99.9 percent of them lacking so it's nice to have the option of a stripped down wireless headset sans bells and whistles! Phew - Digression over! OK back to it - the 4.40? Right - What Sennheiser have achieved with this headset is quite simply the best combination of great sound, great Bluetooth, great materials, great build quality that I've experienced in a wireless headset. And all of this in a moderately priced confection to boot. I say 'moderately priced' as some (i.e. My long suffering wife) quite rightly see a £130 headset as expensive but we all know that this can be an insane hobby for your wallet. And more expensive doesn't always mean 'better'. An example - I've spent £420 on a wireless pair before (Master & Dynamic MW60) and yet I prefer the HD4.40 at nearly £300 cheaper. But it's all subjective and everyone has their own taste so don't judge me too harshly! So build quality wise - it's plastic buuuuut it's Sennheiser plastic. Which believe me does mean something as they always do a fabulous job with materials and their build quality and QC is generally up there with the best. The 4.40 is no exception in this regard and because of its pared back offering it's also the lightest headset I've ever used and in my eyes this makes it ever more truly Wireless. Battery life is up there with the best and though it may not be the 40 hour behemoth of the Beats Solo 3, 25 hours ish is certainly at the top end of what's out there at the moment. And whilst I like the Solo 3 (also reviewed) I much prefer the build quality and sound signature of the 4.40. For one the plastic folding mechanism of the 4.40 inspires more confidence than the metal of the Beats. Strange I know but in my eyes true nonetheless. Sound wise - well It's a very Sennheiser sound and combines the best of the mid centric focus they have always been known for with the added elements of the new house sound evident in their more recent forays into the world of the modern Audiophile. So for that read an extra serving of low end oomph and a bit of extra sparkle up top from neutral. No sibilance at all and for Bluetooth the bass is tight and well formed. Soundstage is just average but that's to be expected for a wireless BT headset although the imaging is pretty good with good instrument placement. Its a sound signature that I really like (and I'm a neutral lover) and it works great when out and about as the extra oomph and sparkle really give it a lively dynamic sound that isn't drowned out by the sound of the outside world. So cons? Not many for me. Some may bemoan the lack of a case but I certainly wasn't expecting accessories at this price point. Some may bemoan the plastic and the lack of refinement and luxury offered by the B&W P7 Wireless (also reviewed)? But the HD4.40 is just shy of £200 cheaper so it's horses for courses. Besides I found the Bass a little overdone when using the P7 in wireless mode something which I haven't found in the 4.40 which is fantastic given the price. The ear cushions are small - about on par size-wise with the Momentum 2.0 (& Wireless) and whilst I have no idea why Sennheiser have such a strict penchant for tiny ear holes, given that I found those models incredibly uncomfortable, fortunately the pads on the 4.40 are thicker and softer and as a result I've not experienced these same levels of discomfort. So result! But I only use mine for commuting do can't comment on longer listening sessions as I didn't buy these for that purpose. So all in all the HD4.40 is a phenomenal headset with great sound, fantastic build quality, rock solid Bluetooth connection (zero drop outs so far) and all this at the same price point as some lesser creaky Sony models and 120 quid cheaper than the slightly less creaky Beats Solo 3. What's not to love? Hope some of this helps. Stew

Good pair of headphones, still a bit pricy though?
I purchased this for just under £100 which is still a bit pricey for what it is but I suppose your also paying for the brand name. It is a brand that I always have loved though. I have always preferred Sennheiser's take on audio on a lot of their headphones. Unfortunately this is not one of them. The sound quality is still great, I prefer audio to be on the neutral side so I can hear the instruments, not for them to be drowned out by muddy base. But I have found recently that a lot of their low end headphones are way too neutral to the point they almost sound tinny. This is not far off but still has hints of that Sennheiser signature sound. They make most of their money from the high end, I understand but a lot of manufacturers are making some really awesome sounding headphones on the lower end these days and I can't but help think that they should be doing better. The headphone is comfortable to wear for long periods of time, thanks to the massive over ear cushions. The underside of the headband, could use much better material and cushioning. Instead, they have used rougher material which I guess stops the headband from slipping off your head but tends to pick up dirt and catch hair overtime. The build quality is brilliant though, it does feel like a high end pair of headphones. Thankfully, it folds. This should be a standard across all over-ear headphones regardless of price point. If you buy this at the price I did, I do not think it is worth the cost. If it ever drops below £70, you should consider this.

Etwas schwerer als ein JBL BT 55 - aber durch das sehr gut gepolsterte Kopfband und die extrem weichen Ohrpolster ergibt sich ein toller Tragekomfort. Die inneren Ohrmuscheln kamen mir erst zu klein im Vergleich zu meinen anderen Kopfhörern (H7,Fidelio X1 und E55 BT) vor, das Gefühl gab sich aber rasch. Selbst bei schnellen Bewegungen bleibt der 4.40 an seinem Platz. Die Sennheiser Kopfhörer waren mir immer als relativ hell und sehr informativ in Erinnerung. Nach dem Lesen einiger sehr guter Rezis habe ich es aber doch mal versucht, da der E 55 BT nicht über aptx verfügt. Und siehe da, der Klang ist echt beeindruckend!! Ich möchte ihn als Schnittmenge zwischen meinen H7 und Bose Soundsports Wireless charakterisieren. Nicht ganz so gut in der Hochtonauflösung aber fast das gute Pfund im Bass, welches nicht zu Lasten der Sauberkeit geht. Als guten Vergleichstest empfehle ich gut abgemischte Filmszenen in Restaurants, wo man auch das Gespräch am Tisch ganz hinten links mitbekommt. Bei Kopfhörern ohne aptx geht das voll unter, bei schlechteren mit gibt es nur ein Nebenrauschen. Da die 4.40BT die Geräusche durch die tollen Ohrpolster nach innen und außen sehr gut abschirmen, habe ich meinen perfekten Reisebegleiter gefunden. Bei sehr kaltem Wetter müssen jetzt sogar des Öfteren die Bose Soundsports zu Hause bleiben. Für ca.150 Euro im Bezug auf Klang und Wertigkeit sind die Kopfhörer eine klare Empfehlung.... Da gerne verglichen wird hier die Klangliste meiner BT Kopfhörer: 0,8. Sennheiser Momentum 2.0 over ear, die Mischung aus H4 und bt 4.40, perfekt ausbalanciert, Bass schön straff und ein perfekter leichter Tragekomfort... 1. BO H7 - die absolute Ausgewogenheit, perlig und trotzdem tiefreichend mit gutem Tragekomfort 1,5. BO H4 ähnlich H7 aber leichter und höherer Anpressdruck für unterwegs....(mehr Bass durch Anpressdruck) 2. SH 4.40 - etwas direkter als der H7, strafferer Sitz , dichter gegen Aussengeräusche, Bass etwas schwächer als H4 2,5 sony mdr 1000x guter Tragekomfort, obwohl recht massiv, NC gut, Klang an sich toll, aber irgendwie nicht "klar" genug für mich, schwierig zu erläutern... keine klare Abgrenzung von Frequenzen, daher durchaus druckvoll, aber verschiedene Bassfabrikate konnte ich nicht unterscheiden, bei M2 und H7 kabelgebunden möglich, meine Frau meint es ist ein typischer Tecknohörer und findet die Gesamtklangwucht super, so viel also zu subjektiven Rezensionen 3. PX 550 sehr schön leicht aber sehr vordergründiger HT-Bereich, schlechte Verstellmöglichkeit-rutscht und daher zurück.... 3,5. Bose Soundlink - bester Tragekomfort, Klang aber wenig differenziert, mein Favorit für Sport ab 5* Grad und darunter.... 3. JBL everest 700 - tolle Ohrpolster-aber auch sehr groß.. der Klang gut, aber neben dem guten Bass nicht sehr differenziert 4. JBL BT 55 - sehr guter Bass, die Höhen aber etwas zu blechern - wunderbar leicht und nur 96 Euro, kein aptx 5. JBL 50 BT - krass direkter Knallklang (Slayer stehen live...), unakzeptabler Tragekomfort und schlechte Verarbeitung - irgendwo dazwischen BOSE Soundsports als In Ear mit toller Bühne und fettem 80 Hz-Bumms..... Gemäß der Platzierung ist der 4.40 der absolute Preis/Leistungssieger und trotz Regen, Sport und Runterfallen immer noch gut drauf.... Fröhliches Kaufen!!!!!

جيدة جدا و بتعد مدة تشغيل كتير بعد بالتلات تيام ما اشحنهاش. منتج و جودة المانية ممتازة. بس فيه عيب لازم اما تيجي تشغلها اول مرة عشان يشوفها الموبايل او اللابتوب، لازم و انت بتغط ع الزرار بتاع الباور تفضل ضاغط لمدة ثواني متواصل لغاية ما يقلب من الازرق الي الاحمر و يفضل يقلب بين اللونين منتظرا انك تكونيكت عليه من الموبايل او اللابتوب. ساعتها الموبايل او اللايتوب ح يشوفها و بعدين تعملها pair. وده مش مكتوب في الكتالوج. بس هيا جودتها صوت نقي عالي الجودة للغاية. و خامتها جيدة للغاية وده بعد تجربة اكتر من سنة. سينهيزر ماركة الماني معروفة.

Son sin duda los mejores auriculares que he tenido, poseen unas prestaciones, una calidad de audio y una construcción excelentes. La calidad de audio es impresionante destacando mucho sus bajos que son espectaculares, en Windows destacan mucho sobretodo activando la función de sonido espacial y en Android si el teléfono cuenta con soporte APTX. En cuanto a comfort es muy bueno, pesan poco y las almohadillas están muy bien acolchadas, he llegado a estar alrededor de 5h seguidas con ellos puestos y sin ningún problema. Quizas la aureola al principio por su diseño molesta un poco pero con el tiempo te acostumbras a ella. La batería es mas que excelente con 3-4h de uso diario solo tengo que cargarlos una vez a la semana y a pesar de llevar ya un año con ellos no noto degradación alguna de la vida de la batería y en caso de que se agote el añadido del cable es de gran ayuda ya que permiten utilizarlos incluso con la batería a 0, eso sí ni el micrófono ni los botones funcionan con el cable. La cancelación de ruido a pesar de ser pasiva es muy buena, he llegado a usarlos en zonas bastante bulliciosas y aún así han enmascarado bastante bien el sonido. He de añadir que a pesar de tener las orejas bastante grandes me caben perfectamente dentro de la almohadilla. Y por último la construcción es una maravilla, son muy solidos y resistentes, el peso está muy bien equilibrado y el diseño es excelente, literalmente he tenido cascos que costaban más del doble y daban la sensación de ser mucho mas baratos que estos. Sin duda una de las mejores compras que he hecho nunca, y los recomiendo encarecidamente a todo aquel que busque unos auriculares de calidad con un precio contenido ya que seguro sobrepasarán sus expectativas y por mucho.

These headphones are simply amazing! What a product by Sennheiser - you've to try it to believe it. Some of my observations are below: 1. Sound quality is beyond amazing. It accurately reproduces the sounds as was composed/mixed by the music artist/sound designer in their studio. I've noticed that Sony and JBL headphones generally add more bass, thereby altering the music altogether. These headphones output music clearly across all frequencies with no bias. You can use your music player equalizer to alter the sounds, if you so wish. 2. The cups provide a good seal against your ear and head, thereby drowning out ambient noise. Once you've got music playing (especially rock or EDM), then you're in a different (and beautiful) world altogether. 3. The cups themselves can be swiveled around, allowing you to adjust the angle as per comfort. However, prolonged use can get a bit uncomfortable. I needed to adjust them slightly every 30-45 minutes. But sometimes, one angle could be so good that I didn't feel any stress for 2 hours straight! Be careful, it'll get stuffy in warm weather. 4. The battery life is out of this world. It says 25 hours and it actually delivers. Analog cable (3.5 mm audio jack) is provided for this headphone, but I've not tried to see how the headphones perform when connected via cable. 5. One thing the user manual doesn't mention is how to connect to a device via Bluetooth. First time is quite straightforward - you switch on the headphone (long press the power button for 4 seconds) and search in your device's Bluetooth settings. But once paired, connecting it to a different device in future is not so intuitive. You need to switch off the headphones, then switch it on again by long pressing the power button for 6 seconds. This time, it can pair with other devices. This needs to be done whenever you are connecting it to a different device. If you are using the same device, then the headphones automatically search for it when switched on. Hope this was useful. Seriously, the headphones are brilliant, especially for the price range. However, it will be useless if the audio file quality isn't upto the mark. I usually play 320 Kbps mp3 files (CD quality) audio and I wouldn't suggest anything below 256 Kbps, else it won't do justice to these headphones. It'll be like driving a Ferrari on pothole riddled roads with heavy traffic.

Je suis très satisfait de ces écouteurs. Je les ai achetés sans vouloir dépenser trop d'argent pour eux et je suis très satisfaite du résultat. Dès le moment où je les ai tenus dans ma main, ils se sont sentis comme de la qualité avec un design simple et discret. Dès le moment où je les ai mis, ils se sont sentis à l'aise. Ils restent en place malgré le fait que je penche la tête vers l'avant pendant que je prends des notes au téléphone - ils restent aussi en place pendant les travaux ménagers - ils ne changent pas du tout. Cependant, la qualité audio (en conjonction avec mon iPhone) est fantastique. J'entends ma musique avec des oreilles fraîches - j'entends des nuances que je n'entendais pas avant. J'entends les instruments individuels qui sont joués. C'est merveilleux. Je pense que la qualité est meilleure avec Bluetooth qu'avec le câble audio - peut-être parce que le convertisseur analogique-numérique dans les écouteurs est meilleur que celui de mon iPhone. Bien que le microphone soit intégré à l'une des oreillettes, la qualité du son sortant est également bonne. La portée Bluetooth est également bonne - je peux me déplacer dans tout mon (petit) appartement en laissant le téléphone derrière moi sans problème d'abandon ou de qualité. Je n'ai eu aucun problème pour apparier et basculer entre mes iPhones et mon iPad. Les commandes sont faciles à utiliser - elles sont toutes sur le côté droit autour de la jante pour que vous puissiez les utiliser avec votre pouce droit. La seule préoccupation, c'est que celles-ci ne sont pas des antibruit - la version antibruit en valait peut-être la peine après tout, mais je vais devoir les porter dans d'autres trains et d'autres avions pour prendre une décision à ce sujet. De plus, si vous utilisez le câble audio (par exemple dans un avion), les commandes de l'oreillette ne sont pas transmises à l'iPhone. Dans l'ensemble, je suis ravi de ces produits et je suis tellement heureux de les avoir choisis.
