We think that Sony might have been a bit unfair to theULT Wear by labelling them as mainly bass-heavy headphones. From what we have seen so far, they are headphones that can ALSO do some very heavy bass but are very good at handling other frequencies. Yes, the slight bass accent is there, but it never overwhelms other sounds. It is pricey, but this does seem like a very good pair of headphones for those who love bass, but not at the cost of other frequencies. And the smart features, good design and good battery life do it no harm at all! (As always, feel free to shoot us your queries - we will do our best to answer them!)
