Might I warn people that these things are powerful. I'm using my ER4S with them, volume set at 2, on low gain. The maximum on the volume pot is 10.

Can someone comment on battery life?
post #63 of 733
10 hours running and still strong
post #64 of 733
18 hours later. It dies. Not bad for a 2 hours charge.

Hahaha. Low gain or high gain?
What can you tell me of the output power (how many mW)?
post #66 of 733
Low gain. Volume position on pot is 2 out of 10. Using ER4S. Which is as loud as talking levels. 3 out of 10 is loud. Anything more than 3 then you're deaf, that's all I can say. Lol. Can't say anything about the output power but all I can say is it powers my Ultrasone PRO750's much better than my Headsix and my Minibox-D

After 3 or 4 days use I'm getting more and more impressed with this little beauty ( and I do mean LITTLE!!) I've switched back to Ety 6i's instead of UE5's and 5Pros. Both UE's hiss somewhat when plugged in - even at low/mid volume levels. Not a huge problem to me -when music starts all is fine. But Ety's are quiet. They take a bit more driving- I tend to have volume at approx 4or5 out of 10 - whereas the UE's are at 2/10 and almost too loud (even on low gain) The bass boost isnt huge - but agree that the T4 adds a nice bit of bass to Etys.

Physically the tiny size is perfect - at the moment I have a 3rd gen nano back to back with velcro dots and a qables LOD. I'm tempted to upgrade to a16gb 4th gen nano - that would match the T4 perfectly!! Same tiny width - possibly thetiniest player/amp combo ever!!

Yes, the T4 sounds nothing like the T1 or T2 and is even smaller. It has a nicer feel to it and works great with my PortaPros as in very open and dynamic.

Anyone cracked the T4 open already? I'm wondering what opamp they use... no tech specs on the iBasso site.

I was told but I can't say. Just kidding. I have an email somewhere with an answer.

This is the first time my UM2's haven't sounded too bad. The highs are there now to clean up the bass, ah, just turned of the bass emphasis.

jamato8, interesting to read you coments on the UM2. I had a pair for an extended test and felt they sounded very good.

Maybe I should get a 2nd pair and try them again. Are yours built recently?

No, they are a few years old with the clear on the cables, not black.
post #73 of 733
But but how does it compare to the Minibox-D?
post #74 of 733
Curse you Head-Fi ... i broke down and ordered one yesterday and the parts for a mini-mini IC today.

Minibox-D. Flat. Makes the ER4S' high's sound grainy, harsh, but more detailed. Bass is there. But not that noticeable.

T4 without bass switch on. Obviously less detailed but less fatiguing as well. A mild bump in the lower frequencies to provide the bass which the ER4S never had.

Comparing mids, they are on par IMHO.
