Etymotic ER2XR

48%of 77 owners recommend
48% recommend · 36% neutral · 16% don't
Owners praise
  • Passive noise isolation is exceptional, with many owners saying it matches or beats ANC headphones and is ideal for planes, motorbikes, and blocking out a household
  • Accurate, detailed, reference-grade neutral tuning that owners use as a benchmark to compare other IEMs against, with strong instrument separation and imaging
  • Exceptional value for the price, often called one of the best bang-for-buck IEMs and worth full price even years after release
Owners complain about
  • Deep-insertion fit is uncomfortable for many, with complaints about painful, tugging, or fiddly insertion and removal
  • Stock silicone flange tips can detach from the earpiece and lodge in the ear canal, a recurring safety scare that pushes many owners to switch to foam tips
  • Poor choice for sleeping since the earpieces protrude and can hurt when lying on your side or back of the head

What Etymotic ER2XR owners say

“Every penny, just first thing to do is to swap the oem cable with a balanced one and you'll be blown by the amount of bass and clarity.”
— lnt976 on Reddit
“I consider them to have a balanced neutral response. It has been my gold standard where I compare every other IEM to. Well worth the cost in 2026.”
— Gransmithy on Reddit
“Man I got scammed like you when I bought these iems some years ago haha these things only work well if the recording of the songs is absolutely perfect”

What Letshuoer S12 Pro owners say

“The S12 is brighter than the HeyDay (to my ears), so I would recommend a warmer amp source to really make them shine, and I would assume that they would pair great with tube amps”
— GlenAppleton on Head-Fi
“I just love my S12 PRO.”
— @fhreire on YouTube
“The bass on most planars including the S12PRO decays quickly. Gives the entire sound profile a lighter note weight and no amount of tip rolling will change that aspect (I went through 12 pairs).”
