Depends on condition of course, but most likely yes. $70 seems fair. I'd pay maybe up to around $120 US new - I believe I paid less than that as a preorder though with different exchange rates now I don't really know. I would not pay the 125 pound non-sale price.
It's a vibrant signature. More coloured than most of the rest of the Trinity line up. It can put out as much or more bass than any IEM I've heard from Trinity without becoming muddy, and it forms a pretty strong V shape with the upper mids and another peak in the lower treble to remain clear, although not particularly accurate as far as timbre goes. But those rises and peaks are still pretty smooth (unlike, say, the Atlas, which I never got on with) and it's a fun listen. Sounds good from phones and cheaper DAPs (and probably better gear too but I have better IEMs for them haha).
