I offer you an overview of the latest model (2009) in-ear headphones from the well-known company Sennheiser. It's about the
CX-180 Street II .

The Sennheiser CX-180 Street II in-ear headphones are perfect for all portable devices thanks to the standard gold-plated 3.5 mm jack. Excellent isolation from external noise, which makes it possible to use the CX-180 Street II even in very noisy places. Sennheiser CX-180 is characterized by balanced sound with an emphasis in the low-frequency region.
Equipment
Headphones are packed in a plastic box. My packaging is now in poor condition, so I took the photo from the Internet.

On the front we see a lot of beautiful words (and even in Russian!), Headphones and interchangeable ear cushions, you will not find anything else in the box. It is a pity that they did not put a leather case like the CX-300, but it could be useful. Coloring headphone case only one - silver-black. The ear cushions are soft and durable, good quality.

Description
I bought these headphones to listen to music through the phone and waited for a good sound from them, because This is the younger model of the already famous CX-300. Good sound waited, good sound and received. The design of the case I was very pleased, they sit in my ears as "dug in." With a long listening ears do not get tired. Noise isolation at a high level. A couple of times the phone fell out of the hands and hung on the wire, but the headphones did not fly out of the ears. The case is durable, I have already managed to sit on them and drop them a couple of times, and at least henna them. The wire is flexible, symmetrical, it does not get tanned from frost and sweat, there is enough length. The plug is L-shaped and this annoys me the most, with my phone (Nokia 5230) it’s not convenient at all.

The sound is powerful, saturated with low frequencies (this is the main advantage of these headphones), which sometimes even lays the ears, but there are dips at high frequencies and at high volume they start to hoot. In general, the sound is decent. The best for this price does not come up.
