I have brought T-Mobile Dash last month and looking for a headphone for listening music with very good sound quality. Though the handset has been also provided with a headphone, but it doesn’t work properly. I am searching for a universal headphone that can be used with T-Mobile Dash very easily. I think I must look for a USB connector to connect a universal headphone, if I am right guys, please suggest me very soon. I have not researched on the websites very deeply yet, because I like to get your suggestions before going to any other places. Thanks.
