Nice unit with great price! You cannot expect that it will compare to high end Sennheiser or Shure IEM systems. 200 euros for IEM that has no issues with signal, works every time with no issues in general is a great price. Soundwise is ok, but again, it is a 200 euros IEM not a high end Sennheiser or Shure. One thing to mention is that I didn't use headphones which come with the unit so I don't know how they sound or feel. I used Mee Audio M6 Pro and TRN V80 which both worked really well.
Lower your expectations to the price.
Cheers!
