Sony Dynamic Closed-Type Headphones MDR-ZX310-L Blue

I got these for my 8 year old son and these headphones have absolutely no right to sound this good for $20. I am an audiophile with 30 years of listening experience and I am absolutely stunned at what they have been able to achieve at such a low price point. Simply put, this level of sound quality just wouldn't have been possible even 10 years ago. What strikes you most about the sound is the sense of dynamics and rhythmic drive. Even out of a bare iPhone 6 with no headphone amp, these 'phones deliver a nice energy to the music, following rhythmic lines quickly and easily. The bass in particular came through with authority and weight and I was impressed at how solid and punchy it sounded - again, for this price point. This is not nearly a high resolution set of 'phones by any stretch - for example, the treble is slightly rolled off to be sure, but personally I'd much prefer treble that is rolled off and still pleasing, rather than the shrill sound that is far too common with cheap gear. They seemed to work reasonably well directly out of my iPhone and Macbook too, sounding just fine directly from the headphone jack with no amp needed. But of course they DID sound much much better with one of my home headphone amps (Naim Audio Headline in the context of an all-Naim system), where they even began to even start to give you a tiny bit of "snap" - but then again, using a set of $20 headphones with an $800 headphone amp is pretty ridiculous and unlikely! But it was a fun experiment. Lastly, the headphones themselves seemed much higher quality than the price would suggest. The earpieces were soft and overall they were reasonably comfortable. All in all, you just can't go wrong with these, and I was simply not expecting this at only 20 bucks. What have you got to lose?

I bought these to use on public transit on my way to and from work. I wanted a cheap pair in case they got broken or stolen. I must admit, when I first opened the package they arrived in I wasn't impressed, but I gave them a chance. I had read all of the negative comments about them. I have had them for a few weeks now and I like them. They are comfortable, the sound is decent, there is more bass than I expected. I also have a pair of studio beats and a pair of studio AKGs that I love. For the price, if something happens to them, I would get another pair. The negative remarks I read must be people who are very picky and hard to please. You can't expect good quality from inexpensive headphones. I am pleased for the price I paid. They definitely don't compare to my beats or AKGs but they aren't supposed to.

These headphones are currently my favorite cheap headphone. They are more comfortable than the tiny headphones, they stay on better than the behind the head headphones. Of course I wouldn't use them for mixing. Then if I wanted to hear my mix in headphones I use Sennheiser MD-600. I use these for such things as watching videos on a laptop that doesn't have speakers, and playing guitar along to a CD. Actually, the real reason I wanted to write a review is to scold Sony for publishing bogus specifications. Sony had a professional audio products division and therefore should know better. The frequency response specification of 10 to 24000 Hz is incomplete and therefore meaningless. 10 to 24,000 Hz +/- .5 db would be an excellent specification. 10 to 24, 000 HZ +/- 3 db would be a very poor specification. Without the variance number the rest is meaningless. This specification is supposed to tell you how much the level of different notes vary within a range of frequencies. Just stating a range of frequencies is meaningless. Sony is implying that the consumer no longer knows anything about audio. It makes it difficult to compare products when the specifications are meaningless. Look at the specifications on Sony professional audio products. They will look more like 30-17,500 Hz. +/- .5 db. They want to show a low variance and so limit the frequency range. An audio db or decibel is the minimum difference an ear can hear. If, within a range of frequencies the variance is +/- .5 db, that means a particular note may be as much as 1/2 db louder than the other notes, or 1/2 db lower. So there may be as much as 1db difference between the different notes in this range. This is barely noticeable. This would be considered a very flat and smooth frequency response. With a variance of +/- 3 db., some notes recorded at the same level would be as much as 6db louder than others. This would sound bad and be considered a very poor frequency response specification.

I attended a training session where these were used and was TOTALLY impressed by the folding design and quality. SO immediately went and ordered this set. I had expected to get the one exactly as ordered (no mike) but it came with the mike on the cord. Rather than immediately get upset, after a lot of checking into things and sources, I found that the units are exactly the SAME in audio quality, and because the unit with the mike is more popular the other seems to be an issue to get. SO now I have a great set of headphones for use with my Canon Video Camera, ZOOM H6, and my Smartphone.. sweet. I'm a Happy camper..

Too much bass. If you have an equalizer you can decrease the bass and the sound is acceptable. I bought the white ones. The color should not matter but it seems to actually matter. After buying two pairs of white headphones I later bought the same model in red. The red ones were garbage because of poor sound quality. My guess is that the color is not the only difference. Maybe the red ones have different construction and materials. The covers that come in contact with your ears are low quality and deteriorate quickly. I bought them and later bought a second pair and then a third pair.

20年ぶりぐらいにヘッドフォンを買った。 よい音のように思える。 少なくとも、PCスピーカーでは聞こえない、いろいろな音が聞こえる。 ただし、コードがもう少し長く、片側から出ていれば、なおよい。

Superior quality! Nice colour. Liked it.

お安く コスパよし 音もよし

Por el precio no puedo creer los excelentes materiales, desde el cable que es grueso y no se enreda, hasta las almohadillas que me parecieron de un mejor material que la mayoría de audífonos del rango, el detalle en plateado los hace ver más sofisticados, y el sonido está muy bien, es nítido y equilibrado, los uso para ver series desde mi iPad o escuchar música aunque para ese fin dependiendo en gustos, se puede elegir de la misma marca unos Extra Bass si prefieres bajos más intensos aunque el precio se va a casi el doble. Además tenían 25 por ciento de descuento, fue una compra muy buena. También los puedes usar por horas y no te cansa o te duele tener los audífonos sobre las orejas :) Lo que sí noté es que en mi iPad suenan muy bien y con mi iPod no, las mismas canciones con la misma calidad de audio... no importa si trato de ayudar con el ecualizador, igual el sonido es muy plano y opaco... pero los seguiré usando con mi iPad entonces.

Good sound and the fit, great priced product would buy it again...
