No..it is not the quantity...but the quality....it is really hard to describe

Sorry...but not really, I mean something negative......still, it sounds good with smartphone..but much better on DAPs like C4, 901(with minibox card) and dx90 which I have tried today....I will try some portable amps this Friday 

Hey, pls don't worry. H8p is still a great IEM, even with smartphones. I am talking about the potential here. It sounds little unreal in bass, if it is not totally driven, but not that much.

Hahaha!! Actually I am a ultra-trier!! that means I'd like to check every "phone out" on hand for my every new IEM and also headphone....I must be crazy....XDDD

You absolutely right!! Thx for the remind~~

It's out of Warranty, they offered me only half year warranty then, and it is already 2 and a half year now....and they also lost my order (I highly doubt it.....)

yep,you are right...I opened both side, and now try to get contact with the manufactorer(try to hold my fire......)

Firstly I must be honest to say that I've got no good impressions of ACS T1(old vision)...the bass quality is even worth then  some $50-IEMs. So I try my best to avoid to review it in this thread...   My ACS T1 was found broken for weeks. And I contacted the Scheinhardt Lab(where I had my T1...
