USAMS Tenna (HSTL)
ø10mm Dynamic Driver

USAMS's Tenna Series earphones got me interested because of their looks and build quality, so I decided to buy them. And you know what? I'm glad I did. These earphones are a pleasure to the ears. They are loud and powerful, yet clear and vivid. Especially good for vocal-based music, and even acoustic instruments. Also suitable for bass-oriented music, even though the sub-bass isn't really deep.

NOTE: This model was most likely discontinued. It is very difficult to find for purchase.

Pros
Cons
  • Very clear and immersive sound quality. The bass is punchy and swift, the mids are precise and clear and the highs are crisp and moderate.
  • These earphones get very loud without any amplification.
  • These earphones are comfortable even while laying down on a pillow.
  • The noise isolation on these while music is playing is near perfection.
  • The design and build quality is definitely unique and eye-catching.
  • The highs are slightly darkened.
  • Even though it's beautiful, I'm not sure that the flat cable was a good idea.

Comfort & Fit

These earphones are short and were designed to be placed entirely inside your ear and they stay inside by leaning firmly against you ear. They are almost flat while inside your ear, and should be very comfortable even when your head is laying down on a pillow. It may be tricky to get an even seal in both ears, but you'll get used to it.

Lows / Bass

The bass is punchy, quick and responsive. Once you get a good seal, you can even feel the sub-bass slightly rumbling. However, can be slightly inaccurate when bass gets too deep.

Mids / Vocals

The mids are clear and dominant. The vocals are warm and pleasantly toned, and don't get pushed back by the bass.

Highs / Treble

The highs are crisp and loud, yet moderate and not fatiguing. Slightly darkened but quite the comfort-zone for highs.
