Pros: On par with most $200+ iem and perform very well
Cons: Lack of bass, Micro-phonic
I had the Re0 since Late Feb and I love it! I was hunting for a bargain at first and when I received mine I was like"meh" then after 50 hours the bass starts to kick in and mids is much warmer now after 200 hrs I ditched my full can(srh840) and removed the filter, much more sharper but that is just me. I would highly recommend this to anyone who is looking for the best item under $100 and if you dont like the original tips try the sony hybrid tips($10 at sonystyle).
Congratulation on the success and a big THANK YOU to HiFiMan for this exceptional earphone and I do suggest a less microphonic cable and maybe offer a wider color selection (Sorry I am baked :)
