I bought this for 11 year old son and he loves it. He already had 4 different brand of ear phone w/c the one side always having a problem ( I'm lucky to get a extended warranty that's why the store just change a new one). After searching web for a earphone with a great quality of cable I found this. I have also bought M16P chrome but always falling from my ears because its heavy, this I think my son don't have a problem( he don't complain) so I bought M9P and it fits my ear perfectly. Now I received a news letter saying I can get HT-21 for only 12$ so I ordered and waiting.
