Great sounding open headphones
I sometimes struggle with the fit of in-ear headphones, so I tried these and was delighted! They're so much more comfortable than the in-ear style, and still have really clear sound! They aren't tightly fitting and they do feel a little bit 'wobbly' however they are surprisingly secure, staying in place when running and exercising. They connect INSTANTLY to my i-phone, have loads of battery life, they're incredibly light weight (so really easy to wear for extended periods) and overall are excellent value for money.Would be nice if the case gave an indication of remaining charge, but I can always see this on the app.

Love these ! Great addition..
Why did I wait so long to get open-ear earphones ? Great, much needed addition to regular in-ear buds (AirPods Pro 2nd Gen in my case).I was using Apple buds for everything, but.. There was something they just could not do well enough or safely enough for me:Cycling, other active sports, unsafe environments and general awareness, etc.Apple buds can slip out and fall, if they don’t fit your ears perfectly (happened multiple times) and cannot match having open ears for hearing outside world.Truefree O2 Are very well made, perfectly smooth and comfortable to touch and wear. Battery life is good, case is solid, bluetooth 5.3 connection is 100 percent stable and in sync.Touch controls do everything required:Play, pause, skip track, previous track, volume up / down, activate voice assistant and activate / turn off game mode.Truefree O2 earphones can also be connected to official app for personalised equaliser settings, touch control changes and firmware updates.- But I have not tried the app, as my setup worked so well, I just didn’t need or want to mess with this. I might later, if I feel the need.If pushed close to ear opening, you can hear thumping bass, but as they just hang naturally, you have to accept them as they are and you cannot do much adjustment other than re-position slightly. The round shape reliably springs back if bent.And that’s how they are meant to function and be worn.They hang a little high on my ears, I think. But that’s subjective and they feel perfectly comfortable and secure and you get used to the sound profile, considering sound is playing from the outside (but still privately if not playing very loud).However, I must say they get plenty loud and I had one of the most enjoyable and 100% safe all day cycling sessions wearing these, no exaggeration !That’s because I could listen to music and be totally aware of surroundings, it’s so satisfying.Oh and no sweat ! No need to take them off to wipe sweat like you do with in-ear phones, if you’re very active. Which is a relief.Also, they sound very clear and natural for calls, both for you and the person you’re talking to.Apple buds sound great, but I would pick these Truefree earphones any day of the week for sports or going grocery shopping, waiting for a parcel (doorbell), things where you need to be reliably fully aware of surroundings or talk to other people. Good value for money too.They recharge fast, last a long time. I Tend to keep volume low / medium level, just enough to enjoy the music, but still hear well around me.Negatives ?Nitpicking, but I would say they announce, ‘Power On’ and then ‘CONNECT’ not ‘connected’ for some reason. And that announcement could be done slightly more quietly. But, that is really just nitpicking.Even my parents enjoyed them, when I asked them to try these on. They liked being able to hear what’s going on around them and said music sounded good.To sum up:All of a sudden, they have become a must have item in my life. I would not be without open earphones anymore.You need both in your life - noise canceling earphones / earbuds and open earphones for different use case scenarios.

Superlight, Versatile and good value
I bought these headphones as I had bought the Truefree 01 before and my wife loved those so much that she has taken them, so when offered a discount on the Truefree 02 I thought I would give these a try.ComfortThese are similar to the other model in that they are super comfortable, but are even lighter thereby making them more comfortable, yet secure. Really easy to put on and the design and lightness means you can wear them for hours without it hurting your ears.SoundThe sound is good and the not tinny. As they are open headphones you expect outside sound to come in, but it is good enough for the commute and particularly the gym. The only place you might struggle is if you want use them in a very noisy environment, but they are not made for that.PhoneUsing them for the phone is simple and does a decent job. People can hear you clearly at the other end and you can hear them with the ENC technologyPracticalityThese are IPX5 so are great for the gym for that reason and they don’t come off easily when you are working out. Decent battery lifeOverallReally decent headphones for the price, usually around £40/£50. The are great for the gym and the commute because I am not worried they will fall out and get lost. Sound is decent and gives you an idea of what is happening around you. Calls are clear too. Finally, these have now been nicked by my daughter like the Truefree 01 were by my wife! Oh well!

Love these! Great sound quality, comfort and mic for a hybrid in/over discreet earphone
I have been searching for a pair of non-intrusive earphones for a couple of years since developing an ear condition which means I can no longer use my in ear Bose earbuds! These did not disappoint at all and for my needs, are pretty perfect!These earphones are super light. The over-ear hook that keeps them snug, which is usually a massive issue for me with my weird sized ears that nothing ever fits! The open-ear design means I can be using these and still hear the world around me, which is super handy. I sometimes forget I’m even wearing them and also when my hair is down, they can't even be seen! Very comfortable and easy to put on. The only draw back is when adjusting them, the controls are super sensitive, I end up cutting off calls mid talking or skipping or ending tracks!I've been using these on and off for a few weeks and still working off the first charge which is great in terms of battery life and charging.The mic is great on calls and people on the other end have not mentioned any issues with background noise on my side even though the open ear design means that background sounds are not completely cut out.The sound quality is on par with my Bose earbuds, very clear and the bass is a great added bonus to my music.The app isn't the best for set-up and sign-up and I would probably say that is one area that needs improvement but the positive is that once up and running, you don't really need the app but I am yet to figure that one out for my needs.The price is pretty good too for what you are getting, even better if you can grab a deal!Overall in all, the Truefree O2 headphones are a fab pick. . Highly recommend for anyone who wants a comfortable non intrusive set for calls and music.Enjoy! :)
