Hi, I recently sent mine back under warranty b/c bass started buzzing (not bumping like it is supposed to). I’m a bass player and need to be able to listen back to my own recordings so this is important. Are others running into this issue or do you think it is a one-off problem for my unit? I want to believe in Nothing.Tech b/c the designs look cool and the sound quality at first was really nice. I guess we will see how the repair-under-warranty goes!
