AudioSense S125

Balanced Armature


I was excited about testing some new AudioSense products. The S125 look very nice, are small and compact and are very well built. Unfortunately, they are some of the worst-sounding earphones out there. They are not capable of bass reproduction, they just rattle instead, like some cheap 1W USB-powered speakers. Skip these earphones at all costs. They do not worth their price.


  • Good sounding high-mids and highs.
  • A very impressive build quality.
  • Nice extras, like a carrying case and a shirt clip.


  • The balanced armature units in these earphones are incapable of bass reproduction. Even the slightest bass content is constantly distorted.
  • Since there is no bass, the mids are lifeless, cold and dry.
  • The earphones are advertised with red-bore tips. They don't have any.
  • No decent retail packaging.

Comfort & Fit

The are very small and one you pick the right tips for you, they'll stay inside perfectly.

Lows / Bass

The bass doesn't exist, and when it does, it's a distorted noise. It just sounds aweful.

Mids / Vocals

The vocals are pushed back and sound very unnatural, they lack volume and presence.

Highs / Treble

The only thing good about these earphones is the high-mids/highs. They are pretty crisp, but that doesn't make the earphones any better.
