Great feedback

  • Got my GO V2+ today and so far its been pretty awesome with my HE400S and UE900 (both SE from my iPhone 6S)!
  • Case is totally great. Solid and nicest design. Good buttons. SE is definitely more powerful and better for unbalanced phones.
  • dead black silent background, no hiss. even with max volume, no music playing. thanks to Larry Ho and team there for such improvements.
  • The sound is great, much better than the GO IEM 100 or GO V1 450. I generally preferred the TCM filter. The SSM filter works well with Tidal    when streaming from my laptop. I noticed that the bass is tighter in particular.
  •  No hiss with sensitive IEMs, even on medium and high gain.Much better heat management than GO V1.Battery life is good. I didn’t test to see exactly how long, but it was sufficient for extended listening sessions.
