Joyroom JR-E103
ø6mm Dynamic Driver

Joyroom have finally exceeded my expectations with their JR-E103 model. These tiny earphones are some of the best I've heard, and they solved most of the issues we had with Joyroom JR-E107. They offer [slightly] louder audio output, much deeper bass, better durability of the nozzle meshes, and much wider nozzles - which means they support a huge variety of ear tips.

I highly recommend getting this model as soon as possible - pleasure guaranteed!

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

  • Simply amazing sound quality. Clear mids and crisp highs with no distortions. Deep and powerful bass response, not overbearing.
  • Louder than most tiny earphones.
  • As always, Joyroom provides a great build quality for these earphones as well.
  • Extremely comfortable to wear, thanks to its tiny size and light weight.
  • Slightly recessed mids compared to the lows and highs.
  • The sub-bass isn't very pronounced.
  • The maximum loudness is still lower compared to what you would get from earphones with larger drivers.

Comfort & Fit

Used the pre-applied tips and got a perfectly comfortable seal for hours. No issues here. Since the nozzles are very wide, you can even use your favorite ear tips with these earphones.

Lows / Bass

Fast and quite deep bass. Unlike Joyroom JR-E107, these earphones offer such a bass quality that even bassheads can appreciate. Still, don't expect them to outperform earphones with larger drivers.

Mids / Vocals

Some of the best mids I've ever heard, very warm, detailed and surrounding, even though slightly recessed. Perfect for vocal-oriented music genres and even metal music, and for prolong listening sessions.

Highs / Treble

Fantastic crisp and precise highs. Gentle and not fatiguing, perfect for prolonged listening sessions. Absolute pleasure. Slightly more balanced and natural than Joyroom JR-E107's highs. Just a bit on the quiet side.
