great headset without complete shielding of ambient noise (traffic)

I was looking for a headset that "in-ear" is almost, but not completely shields any noise. Since I have the Bluetooth headset from Bose I knew these ear tips already. For the way I use the headset in combination with my Blackberry Z10 and Apple iPod Shuffle.
Making calls via headset works just fine - the music stops when a call comes in. Similarly, the volume control on the headset itself works without problems. The same can also be said of the iPod. This disappears either in small Fächlein jacket or angenkippert somewhere. The volume control works without problems on the headset, so no handle to "hardware" is necessary here.
The sound quality is very pleasant - from classical to pop to techno. Only the basses come across not so, but this is due to the slightly looser fit. This is also intended, as the noise will not be screened to 100 percent. The inserts fit perfectly, even during sporting activities. by the curves they sit bombemfest in the ear.
The short cable (extension included) is perfect for me. A longer I need (currently) just do not.
