Surprisingly good
I was afraid to try the design but it was surprisingly good, now i wonder why i havent seen other brand do similar product like this. it also has a very clear mic and talk even in a busy area thanks to its ENC capability. It has also a great stereo sound and really comfortable for long hour calls and music. cons: has a huge case(like twice the size of a normal buds) although its not an issue for me since i mostly used it with my runs and walk, with its big battery capacity i dont need to bring my case with me.

Truefree delivers quality without hurting your pocket
“I was looking for a Bluetooth headset that I can use for running and working out – without falling from my ears as in-ear types tend to slip after minutes of listening. I have tried a sports model of a well-known brand with ear hooks before, but it sounded poorly due to its deficient bass response – it can be compared to listening to an AM radio with the bass muted. Luckily, I discovered Truefree 01 Bluetooth Earphones on Amazon, and my listening pleasure has never been the same and increased to a new level. It sounded great with excellent bass response for music, movies, and calls, and fit my ears perfectly with its ergonomically designed ear hooks. Now, I feel naked going to the gym without my Truefree earphones. Regarding the price, it’s very affordable. I realize that you don’t need an expensive earphone to achieve high-quality sound, Truefree delivers quality without hurting your pocket.”

Comfortable & Lightweight For outdoor
Pros✅ Comfortable & Lightweight– The open-ear design and soft ear hooks make them easy to wear for extended periods, ideal for workouts. - Clear Sound Quality – Features16.2mm enhanced bass drivers, providing a solid audio performance, though not as powerful as premium brands. - Stable Bluetooth 5.3 Connection – Ensures fast pairing and a low-latency experience, suitable for streaming and gaming. - Long Battery Life – Up to10 hours per charge, with a total of 54 hours, when using the charging case. - Transparency Mode – Allows users to stay aware of their surroundings, great for outdoor Cons❌ -Limited Noise Isolation- The open-ear design means background noise can interfere, making them, less ideal for noisy environments. - Mic Performance – Some users note that the microphone sounds hollow, affecting call quality. Sound Leakage– Since they don’t seal around your ears,audio may be heard by people nearby at higher volumes. Touch Controls Can Be Sensitive – Accidental touches might cause unwanted pauses or skips.

Very dissatisfied
Where shall i start, basic and useless app, constant glitches in bluetooth, sometime one ear piece work the other not. No on off at all, need to charge to wake it up.... And the best thing IT STOPPED WORKING IN 2 WEEKS, now it does not connect at all.

Excellent ear buds for work or play. Love it
I bought this for my workouts but I found it impressively useful during my online meetings as well. Considering this is not “in ear”, I found the sound quality very good and immersive. The best part is that I can still hear what is happening around me. Very good battery life. This just works for me. I’m loving this.

Comfortable, decent sound
The earbuds are very comfortable with decent sound and the instructions and controls are simple. Not yet tried the app with the earbuds but still good. Definitely worth the price. Just nite that the earbuds need to be charged for a few hours prior to first use despite the case showing a 60-99% charge. Minor update after 2 months- bit loose on the ears (not snug enough) and could fall off at times. Love that it connects 2 devices.

هذا ما تبحث عنه بالظبط
منتج ممتاااااز .. استغرقت وقتا طويلا في البحث عن سماعه جيدة .. واتخذت قرار ان اشتري هذه السماعه بعد ان رأيتها عند أحد اصدقائي و طلبت منه ان اجربها و بعد ذلك حزمت امري في شرائها لقد ذهلت من نقاء الصوت و شكل السماعه جميل و مريحه في الأذن و بطارية تدوم طويلاً .. أنصح بالشراء دون تردد لن تندم على مالك المدفوع كن على ثقة - يوجد عيب واحد أن صندوق السماعات كيبر جداً أأمل ان يتم مراعات ذلك في الموديلات القادمة
