Pros: Bass is boosted about 4 dB across both sub-bass and mid-bass, and it holds that level all the way down to 20 Hz, so electronic and hip-hop tracks get real weight and rumble. The midrange from 200 Hz to 3 kHz sits within half a decibel of target, keeping voices natural under that bass shelf. At 37 ohms and 105 dB/mW it plays loudly from a phone, and it weighs only 6.5 g per side.
Cons: A Harman preference score of 64.4 in hobbyist measurements reflects a tilted, bass-heavy tuning that will feel thick to listeners who want neutral sound. The presence region sits about 2 dB low with a 3.6 dB dip near 4.3 kHz, which pushes vocals and guitars slightly back, while a 4.1 dB peak near 8.1 kHz can make cymbals splashy. There is no inline microphone for calls.
