Sennheiser sound good:

For Sennheiser price really makes a wonderful product, this product is used rather located towards the entrance of range in terms of sound, but it offers us what the best:
The good ones:
-Very Comfortable headsets uses a material that breathes it allows our ears to not be too uncomfortable
-The Helmet is not too tight and offers adaptation quite suitable to any type of head
-The Sound is warm enough, the bass is strong
-The High are of good quality but not too strong
-The Cable have a very good length

The bad:
-J'aurais Preferred to see a cable a bit more rigid and strong
-The 'Mids' are drowned out by the foundation can and senior
-The Design 'soft touch' attracts a lot of dust and degrades quickly enough, a very disappointing retail from Sennheiser

In all a good buy despite the disappointing soft touch design and can limit a cable Sennheiser has done a very good work on this helmet. Around the same price other choices are quite limited, beyerdynamic offers a good helmet the DTX910 (5 euros more, as a rather ugly design but its equally beautiful) and Dennon also offer headphones for 10 more.
