Joyroom JR-E103

ø6mm Dynamic Driver


These tiny earphones by Joyroom are unexpectedly good, and even solve some 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.

However, when it comes to sound quality - clarity was reduced and some muddiness was introduced. Even the treble got less impressive.


  • Excellent 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 their tiny size and light weight.


  • Slightly recessed mids and highs compared to the lows.
  • 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

Quite decent mids, very warm, detailed enough and surrounding, even though somewhat recessed. Great for vocal-oriented music genres and even metal music, and for prolong listening sessions, but not enough if you're looking for something extra-crisp and truly impressive.

Highs / Treble

Crisp and precise highs. Gentle and not fatiguing, perfect for prolonged listening sessions. I would say that while they are less prone to sibilance compared to Joyroom JR-E107's highs, they are also less impressive and just a bit on the quiet side.
