I don't like heavy/overpowering bass, but still these headphones are appealing when it comes to bass. Basically, they sound like Sennheiser M2 IEG if you lost almost all the bass, which is regrettable. The wireless connection isn't the best, but better than most. For example, putting my hand over the receiver is enough to lose connection when my phone is like 40cm away. However, as long as nothing thick is covering the receiver - it works fine. Battery life is ok too, but the ear buds are horrendous. The foam ones aren't very comfortable to me, but the rubber ones are even worse. They are the worst rubber buds I've had in years. The worst part is that the canal on which the rubber/foam buds sit is very narrow, so most aftermarket buds fall off way too easily. The canal is made out of very thin plastic too, so I expect it to become brittle and fall apart within an year or so.
