Hi, in comparison to the Byron these are the (much) older model. Should have a decent sound, with smooth treble.
I do have the DX 160. Also smooth, and VERY bassy. The 102 are supposed to be a step down from the 160, which is newer and has a higher MSRP. At the time Beyer presented the 160 as "our best to date".
The 102 should be a pleasant listen according to reviews. Check out the What Hifi review from several years ago.
