Ucotech RE-1 - ranked #140 of 1490 In-Ear Headphones · Editor's rating 4.5/5

#140 Ucotech RE-1: $90 Discontinued eBay

Pros: A 10 mm carbon nanotube dynamic IEM with a preference score of 80. Bass is full to 20 Hz with a 2.3 dB upper bass lift, and everything from the midrange through 8 kHz stays within about 0.5 dB of target.

Cons: The top octave sits 4.7 dB low with a 7.6 dB dip near 10.3 kHz, so it lacks air. It is discontinued after selling for about $90, impedance and sensitivity are not published, and the score rests on a single measurement.

Is the Ucotech RE-1 right for you?

Buy it if

you want the tuning most listeners prefer in blind tests out of the box (Harman score 80).
you want sub-bass rumble that reaches down to 20 Hz.

Skip it if

you want to buy it new: it is discontinued.

Frequency Response

How the Ucotech RE-1 measures across the audible range, against the Harman in-ear target that most listeners prefer in blind tests. Where the line sits above the target that range sounds louder (more bass, brighter treble), below it quieter. The curve is a single measurement, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
