The bass was great it is clear and has no distortion. The treble is great if you switch off the bass up button. (for the best results get a phone or tablet that has dolby atmos, I tested it on Samsung galaxy tab a7)
Its 40mm drivers deliver high resolution sound
It has memory foam earpads. You can use it the whole day
It can last for 60 hours. Recharging from 0% - 100% is 1 hour
It’s shs 4,800 (at sweech.co.ke) jbl and sony headphone with similar features is 10k and above
I think I have either the Q20 or Q30s in the house - I can’t remember which is which. They are okay headphones but nothing really spectacular and you have to pay much more to get something decent. The connection is solid though (ble) and I use them occasionally. I think the clamping force is a bit on the higher side, it seems okay for the first 30 minutes but after an hour you want them off your head. So choose carefully.
I don’t have the Q10s and wouldn’t buy any headphone which you can’t tilt the earcups. Other than that they are decent.
