What I can say though, is that the listeners have a really good sound, nice plump. You also sit very pleasant on the ears, even when wearing glasses and after several hours. Have this compared to the Rs 170 and must say that this velor ear pads are more comfortable to wear. Also, I like the sound Rs 180 in direct comparison with the RS 170 even better. The RS 170 are closed headphones and the leatherette expressed quite a bit on the ears.
All in all a good buy. Sure, there are even better radio receiver, such as Rs 220, the cost of 400 and it has an optical output ... But for me as an acoustic Borrow this handset are quite sufficient.
