I've always liked to have heard with Sennheiser headphones music and the Sennheiser CX 3.00 Add-ear headphones I've bought. Priced a bit pricey but worth every penny in my opinion. The quality of the headphones are easy, only to picures Top. 2 days ago a lot of the right earphone out and got already a new guarantee on return. So I am more than happy =)
