Blessing 3

58%of 33 owners recommend
58% recommend · 27% neutral · 15% don't
Owners praise
  • Exceptional detail, resolution, and vocal clarity that owners describe as among the clearest they've heard at this price
  • Becomes a long-term favorite or 'endgame' IEM that owners keep reaching for even after buying newer, pricier sets
  • over-delivers for its price bracket, competing with higher-end IEMs and standing out in the mid-fi category
Owners complain about
  • Recurring mid-bass dip leaves the low end feeling thin, muted, or nearly absent especially compared to rivals like the Aqua
  • Lean, thin tonality that leaves vocals and instrument body sounding unnaturally lightweight
  • Bright, sometimes harsh upper treble that can feel piercing or fatiguing on long listening sessions

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).”
— StolenServiceAnimal on Reddit

“not me cranking +6db of bass on my blessing 3s as a joke and being pleasantly surprised.”
