Managed to get my hands on one too. Have to agree with Weithulu about the sound. I have both the v2 and v3 Pistons. (prefer to use the v3 because of comfort but like the sound of the v2 more) and this will def. replace them. it has the comfort of the v3 with improved sound of the v2. if only they put the remote on the same place as the v2 (but that's personal) they're indeed RMB 99 (but the v3 are RMB 69 now) but worth the money.
