Highly recommend!
Easy and comfortable to wear, great for listening to music while cycling, running or just about in the office, so I can still hear what's going on around me. The touch command feature is also great and easy to work with. Highly recommend!

Faultless for the price
For the price, especially Vs more expensive options, they're faultless. Have used some more expensive options and they didn't last. They don't sound as good as more expensive options but honestly, for the price difference, it's a fair compromise. You're never going to get anywhere near audiophile quality with open ear headphones. Highly recommend.

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

long battery life, clear sound
i purchased these in august 2026, after trying another, slightly more expensive set from a dutch supplier, that unfortunately cut the sound every 5 seconds, or so, so i looked around for another set abnd finally settled on these, and i must say they are marvelous, the sound doesmn't cut out after a few seconds, i can wear them all day at work and they are still at about 95% power, the case is great too, i had a few problems getting them to work, but i didn't realise that they had to be fully charged to pair with my phone the XIAOMI POCO M7 pro 5G, but once they were charged the pairing was easy, they are also clear when taking or making a phone call well worth the money would buy again in the future and would reccomend to anyone looking for this type of headset

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.
