Yooo Koreans represent! Welcome to flatters
Both
@baskingshark and
@samandhi have given you excellent pointers. My two cents:
1. You will find two suppliers of "popular" earbuds: companies (e.g., Fiio, Yincrow, Venture Electronics, DUNU), and DIYers (TGXEAR, Rikubuds, LREY, etc). Interestingly, I think only a couple of folks have heard a good bunch from both camps (maybe
@Ace Bee,
@Kenyon,
@jwilliamhurst). I personally have mainly stuck with DIYers from the get-go: you normally get excellent customer service, good to great price-to-performance, and customisation options. All the DIYers I've mentioned are great to talk to. Jim (maker of TGXEAR) is a classically trained Korean-Canadian artist, and I personally love his sets for classical and jazz.
2. Fit fit fit: don't waste money on a TOTL or >150 USD set and realise you can't stand the fit! Having said that, there are accessories that can help improve the fit: silicone wings, silicone rings, thicker or thinner foams.
3. Look at classified ads on Headfi, HifiGuides, and Discord channels. There are often at least a few good bargains up for grabs. E.g., Ace Bee is selling sets at like 50%+ discounts.
Otherwise, welcome again and do share your experience!
