V_SoulI review them they sound clear the volume is normal on my cell but i feel like the sound is very clear. I plugged in my pc crank the volume and the sound is very clear no cracking i feel like an amp would work well with this one. The bass is nice comparing with JVC HA-FX102 that sound much loud and the bass is overwhelming but cannot handle higher volume pre-burn in. This in the other hand u can put higher volume and still have a nice sound coming from them.
