I didn't love it, the sound is very low and if the volume of the file is low, it doesn't amplify at all. I bought them to listen to audiobooks, but it doesn't sound clear when I talk on the phone. If you wear them for more than forty minutes, your ears start to hurt. I tried them for running and they don't fall off the ears, it has a good battery.

Good for talking on the phone but has very poor performance in music (the bass is non-existent). I thought the clip for attaching to the collar would be helpful (the hook is made of rubber with a magnet on the edge to attach to the main body of the Bluetooth), but it easily loses contact and the Bluetooth hangs. The attachment to the ears is quite convenient, at least for me (the headphones don't move at all during running). The battery has a low duration. Overall, very mediocre.

Extremely good headphones for the gym but also for other activities. The only thing I would like it to have more is the bass, apart from that I was satisfied.

I use them on my PC and I am completely satisfied!
Instant pairing, just like the connection, very good sound, clear with satisfactory bass and with 0 latency!
The battery life is as advertised and it charges quite fast.
At a distance of 7 meters in another room with a wall and a closed door, the sound is excellent,
as long as you don't move (don't walk), when you move beyond 4 meters from the source, it has small interruptions.
The ultimate value for money!
