What KZ EDX Pro owners say

“they are really nice”
— @peanutbutterbean1738 on YouTube
“Insane audio quality for 5 bucks.”
— @BernardoOne on YouTube
“KZ EDX Pro never sounded good in the first place. Very V-shaped sound which bleeds all over the mids. The bass is although pretty satisfying. The treble is sharp and mids are practically non-existent.”
— Paulex57 on Reddit

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).”
