Very good sound, loud! Its battery is off in 2 years, but it has a cable so you can still listen with a cable!

I found them in front of me for 10€ per hour, while my own "greeted" me, I didn't think about it! It has buttons for volume, song change, on/off, and most importantly: it accepts memory cards!!! Excellent sound both in song playback and in calls. I would say it's value for money. I have changed many headphones over time, from cheap ones for 3€ to full branded ones, and they didn't last.. These here are the best.

After listening for years at full volume with flea headphones, these really take the sound intensity to another level that I had never heard before. It's like having a wireless mini speaker when you turn them up to the max, both from the phone and from the headphones.

After more than two weeks of use, I can say that the sound is quite flat but satisfactory for what you pay, and it's fine for the ears after two hours. I haven't tried it for longer. If you want to listen at full volume, only through Bluetooth.
