Theres no official recommendation for earbuds.unofficial ones were
Any of the Sony MDR earphones – even the cheapest ones – have a mostly flat response, and a frequency range of 5-24kHz.
Only avoid the ones that specifically mention Extra Bass.
Today I’m getting new earphones following a recommendation I read by @Sirchiropractixalot . I’m getting the 1More Triple Driver In-ear earphones, which supposedly provide a pretty flat response. @SaintSovereign mentioned in one of the Ultima posts that a flat response was important for subs, so I figured I’ll test this out. Pretty excited to see if I feel the difference.
I just got myself the Between Pro earbuds. I will test to run an Ultima tomorrow and report more but they have quite a good flat response, much flatter than most earphones. They sound absolutely amazing and while they are not artificially „bass boosted“, they have the most amazing bass I ever heard through their physical triple speaker driver setup. Just played a loop of „Bad guy“ and it felt like on a fucking concert.
Most earbuds arent that flat compared to a quality headphone though
