Audiosense seem to gave fallen of a cliff since the t800

@Codename john Its the opposite IMO, the DT100 and the DT200 are great iems. But not this one....

Fairplay. I've heard the AQs and I have not impressed. I haven't heard the DT series so I can't comment

@Codename john I take both the DT100/200 over the T800.

I suggest you ask Audiosense for a replacement. Quite sure your unit is faulty. I graphed mine and its identical to Audiosense marketing graph. And mine sound alright too.

@Another Audiophile mine, tgx78, Akros and Hatena all have the same graph. If thats a QC problem on something that costs as much as it does, well, thats even worse..... (and its very unlikely to be a QC problem, as Audiosense is well known to have good QC)
