I bought the SE215 about a year ago and was rather satisfied with the product so far. The sound is very bassy and the centers are not 100% clear, but one can probably not expect from a Inear in this price range also. The Gereäuschdämmung outward, however excellent, especially with the earpieces that work like earplugs. At first I was skeptical whether the durability of these earpieces, but that was unfounded. Even though the headphones are very large for Inears is the comfort in my opinion, very good, since the earpiece and the wire-reinforced cable over the ear headphones keep in any situation firmly in place. What is, however, very uncomfortable, are very very strong noise that causes the cable if it rubs against something, for example. The very rigid structure of the cable transmits it sounds very far, be transmitted so that, for example, also in the amount of noise Buckle (!). The headphones are not really to use when a lot of movement in the game, and the cable is not adequately performed. (My workaround are small clips with which I hold the cable in place, but that should not really be necessary.) In addition, the connector is really very large (wider than a iPhone5), but does not seem to properly protect the cable approach. So the beginning of the cable has turned black after a year, I would be attributed to oxidation. Also located on the left ear a loose connection found in the area of connection to the cable. This I find very regrettable, because I have chosen mainly from the hope of these headphones would last longer ours. The reason was that you can buy more the cable separately. That does not help one, however, if the connection to the headset after one year gives up the ghost. Since I still have warranty, I will change the headphones, but this joint just looks flimsy, so I'm afraid the next defect after the warranty period to have to buy new headphones. Summary: +: Heavy sound, excellent noise insulation, high wearing comfort -: Unergonomic plug, cable noise, short shelf life Who does not mind that a 100 euro headphones after 2 years is broken, can safely access, for everyone else it is probably to look for alternatives.
