Shure - SE315

Yeah they seemed too good to be true. I've just stuck with my shures. I've had to replace the chord a few times but the actual IEM's have lasted me 6 or 7years so far.

Their impact can't be overstated. In my country, Costa Rica, they quickly became super popular with musicians and regular folk alike (even if they are not flat IEMs lol). To the point where musician friends would comment on my KZ ZSN PRO, ask where I got them, and such. Random people such as bus drivers and pedestrians would comment and mention they knew how good they were. Bang for the buck when they came out was unmatched in the mainstream. Personally, after an awfully disappointing buy in the Shure SE-315, I lost faith in IEMs. The KZ ZSN PRO were way more fun to listen to for 1/10 of the price. Then I got the CCA CRA and was marveled at what could be achieved for twenty bucks in the IEM world. I gifted a friend a pair of CCA CRA, and they became their gold standard. No wireless earbud they have had since then has compared to those CCA CRA. KZ is responsible for me now owning my endgame, the 7Hz Timeless II. I am probably not going any deeper in the rabbit hole but you can bet your ass KZ got me gifting IEMs to my friends who use shitty wireless buds lol.

Shure 215 is the best value option. It's generally good enough for singers and instrumentalists, and can be made to work with bass if you mix it right. Shure 315 adds another driver, but also adds a bit of cost. If you want a little more ooomph on the low end, I roll with Westone UM30 -- but any two or three driver IEM will have much better and clearer bass response than a single driver.
