Meet the baby child of KZ HDS1 and KZ HDS2. These earphones combine the highs of KZ HDS1 with the bass power of KZ HDS2, and enhance them even further. What do you get? Great-sounding earphones. Punchy and deep bass (but still not too deep, considering the driver size), crisp mids and sharp and bright highs. However, the loudness is still insufficient.

Comfort & Fit
I had to use the L-size tips to get a good seal. Overall, these earphones are really comfortable, and you basically forget that they are in your ears.
Lows / Bass
The mid-bass and lower-mids are present, warm and quick. These earphones import the bass qualities from KZ HDS2, and there's even slightly more sub-bass added to the mix.
Mids / Vocals
Thanks to the improved lows and highs, the vocals finally sound warmer, but the maximum loudness still isn't sufficient and you must have an amplified source.
