Do you know where I can adjust the bass and various other settings? Do I access it through an app? Because I downloaded a Marley app from the Play Store but nothing...

- Sound below average
- Bass not good
- Battery decent
- Signal starts to fade at a range of 5 meters
- Weight unbearable, excessively tiring due to the heavy metal they have
- They fit very, very poorly on the head to the point that after a while you get a headache.

Simply a bad choice of Bluetooth headphones

Great headphones, very good battery, I forget to charge them and also you can use them with a cable so they don't consume any battery, very good sound with nice bass and good isolation. Not so comfortable in the ear as they can become uncomfortable after about an hour due to the pressure they exert on the ear.
Range-wise, due to my work, I've tested them up to more than 20 meters. I can leave my phone and have no interruptions at all. I have also recommended them to friends who are also satisfied. I wouldn't recommend them at 180, but at 120, I don't think there is anything comparable.

After about a year, the small screws on top became loose and fell off. I contacted the authorized dealer in Greece (BERSON BROTHERS K. SARAFIDIS S.A. & Co.) and they asked me to send them via courier at their expense. A few days later, they sent me NEW headphones. True professionals. This is also a motivation for purchasing these specific ones, as you know that in case of any issues, there is a reliable dealer to help you.
