I got the 1st generation AM15, ok lang sa HT pero hindi ganon kaganda sa sound reproduction ng music but it can play loud if you want. Although powered sub na, placement is crucial to get that bass you've been wanting to hear & feel (if you can). I have it installed in the bedroom because it's less obtrussive & it has the WAF. I also happened to hear my brother's in ear triport headphone of bose, bass is ok but the mids-highs are not that great & the silicone tips damages easily but bose always replace it for free. But my Phillips SHE9700 & Sennheisser CX400 sounded much better than bose in ear IMO, well that's just me.
