i find that the sony ones that came with my phone just don't stay in my ears. they are only the standard ones that came with my phone. What i do is use the headphone adapter and use a set of seinheissers. Cheap, durable and sounds great. my brother has just order some inner ear ones (not sure which model) but if they are any good i will replace them with the inner ear ones as the seinheisser do occasionally get uncomfortable when im wearing my motorbike helmet
