they are okay but first off I would suggest not using realplayer and getting Pocket tunes....
Secondly I would get the seidio 2 in 1 adapter where you can get a good set of ear buds and have better sound quality. It functions as a headset for listening and an audio headphone set.
When you are listening to MP3's and you get a call it breaks into the song and alerts you of a call.....real nice product...
As for Pocket Tunes...AKA Ptunes it is a much better all around player and there is also The Core Pocket Media Player AKA TCPMP. It handles music and video......Plus TCPMP is free.....both are much better than Realplayer on the treo |
