    • Excellent purchase, flawless after a week of use!

I have been using this earpiece every day for a week now, and I am absolutely thrilled with it. I mainly use it for work calls and while on the move, and it performs beautifully. ● Great battery life: In these past seven days, I barely had to worry about charging it. The digital display on the case is super convenient to see exactly how much power is left. ● Super comfortable: The over ear hook design fits perfectly. It stays securely in place and doesn't hurt at all, even after several hours of continuous wear. ● Clear calls: The built in microphone works great. People can hear me clearly without any static or background noise, which was the most important thing for me. So far, the experience has been 10/10. Highly recommended if you are looking for something practical and high quality! ... show more

    • Good quality but physical design is not for smaller ears like mine.
Color: Black
Sound quality is very good, but I think my ears are too small because I can't keep it securely on. I need an over-the-head "on-ear" model I think.

I really like these headphones. They are comfortable to wear, and the over-ear design keeps them securely in place, especially when I’m walking or doing other activities. The built-in microphone works great for calls, and the hands-free convenience is really practical. The Bluetooth connection is easy to set up, and the charging case is a plus, as it keeps them protected and ready to use. I also appreciate the long battery life, so I don't have to charge them constantly. Overall, I think they are a great choice for calls, work, and everyday use. Considering the price, they offer good quality and comfort. ... show more

    • Not for every ear.
Color: Black
Won't fit around my ear and have the ear bud in my ear. Too rigid to be used properly.
