Sound quality description

In this review, I use the standard eartips size L and drive it with the FiiO M15.

 

The LETSHUOER S12 has a near-perfect neutral sound balance, near-perfect texture expression in the midrange, and fairly good localization. Phase consistency is good, and distortion should not be a problem at the correct volume.

 

On the downside, it is prone to distortion at higher than adequate volumes, which can be a bit of a problem for those who normally listen to louder or enjoy classical music.

 

Please see here for detailed reviews on sound quality.

 

Sound quality general comment
  • Original Sound Fidelity: A+
  • Recommendation: S+
  • Personal preference: S+

 

The LETSHUOER S12 is a very good earphone with excellent phase consistency, braking characteristics, and high-end-like range and resolution. Not only is it unquestionably one of the best earphones in its price range, but it is also one of the few models in the entire price range that offers such sound balance and audio specs.

 

The only drawback is that distortion becomes noticeable relatively quickly when the volume is raised above a reasonable level, but this should not be a problem as long as you listen at a reasonable volume.

The LETSHUOER S12 is a milestone in which a hidden brand that has already delivered a variety of earphones as an excellent audio brand has shown its outstanding ability in the planar drive type. What is surprising is that they have also reached new tuning ground with these earphones.

 

I would like to end this review with the pleasure of being able to introduce you to this new frontier of LETSHUOER.
