I'm sure someone out there has reviewed these, but I can't seem to find any. Can anyone tell me what they think of the Penon IEMs? I've just been wondering about that for a while and was hoping someone would clear it up. I'm not buying anything from Penon right now so perhaps some impressions might help me think about tacking them onto a future order. Comparing them to the sound of other IEMs would help, I've listened to MEElectronics M11+, Shure SE215, Westone 1, and the relatively new Xiaomi Piston 2's. My current daily drivers are the Vsonic GR06, love 'em. If someone could offer some insight, it's much appreciated. Thanks!
