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.

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.

Good headphones

I recently got the Truefree O2 wireless headphones, and I’ve been using them for a while now. Overall, I’m pretty impressed, but they’re not without a few quirks.First off, these earbuds are super lightweight—I barely notice them when I’m wearing them, even for hours at a time. The over-ear hooks feel soft and flexible, which is great for comfort, but here’s the thing: they don’t fit snugly on my ears. They feel a bit loose, especially during workouts or any fast-paced activities, which can get annoying. I wish the fit was more secure because the design is otherwise really sleek and practical.What I love most, though, is the sound quality. The audio is clear, natural, and surprisingly well-balanced, with decent bass that doesn’t overpower the rest of the sound. The call quality is also top-notch—thanks to the dual microphones and noise-canceling tech, everyone I’ve spoken to says I sound crystal clear.The open-ear design is a feature I didn’t know I’d appreciate so much. I can listen to music or podcasts while still being aware of what’s happening around me, which makes them perfect for running outdoors or biking. The situational awareness is a big win for safety.And then there’s the battery life—wow. I easily get around 5 hours on a single charge, and with the charging case, I’m good for a total of 14 hours. It’s one of the best parts about these earbuds, especially since I hate constantly worrying about charging my devices.The app is a nice touch, too. I can customize some settings and even switch between devices easily, which is super convenient for juggling between my phone and laptop.If I had to sum it up, I’d say these headphones are great for sound quality, battery life, and staying aware of your surroundings, but the loose fit is a bit of a dealbreaker for intense activities. If you don’t mind that, they’re definitely worth a try.
