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.
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.
