What's in the Box
Just normal bass, expected a lot , but does decent job
The HD 450BT's are renowned for the strong bass, boy do they perform to full expectations in this range. The sound is full but with good clarity as well. For me I would like a little brighter mid-range, but that is only my personal preference. A brilliant set of cans for what is a very competitive price point.
These are a great value for the money! Sound, comfort, control... alll good.
Very clean audio quality and battery is very good
