Yes, definitely go by measurements. Can’t possibly go wrong there. At 50 bucks they must be the best bargain in all of audio. Ehem. I’ll recommend the Timeless 7Hertz as a great all-around IEM.
Best In-ear monitors under $350?
I currently have the Blon BL03 and Etymotic Er2xr. What are the options in IEMs under 350 that are definitely an upgrade over these two? I'm considering Moondrop Aria 2, or the Blessing 2. My favourite genres are Rock, Metal, Jazz, and blues. I prefer a warm neutral sound, but I'd like the mid-bass to be a bit more elevated than the Etys. Also, is BQEYZ Summer a good option?
