The next in line are the massive DT5. These earphones are heavy, probably the heaviest KZ earphones I've seen so far, and I bet it's because those are dual-driver earphones. The DT5 are among the best KZ earphones. The bass is punchy and deep, much deeper than RX, with pounding sub-bass. The mids are precise and clean, even if slightly pushed back, as is expected with V-shaped sound signatures. The highs are crisp and very enjoyable, not fatiguing at all. They may not be that pretty, but they are a KZ gem in my collection.
NOTE: This model was most likely discontinued. It is very difficult to find for purchase.
A brilliant sound quality. The bass is massive with sub-bass thump, the mids are loud and clear and the highs are gentle and pleasant.
Excellent volume levels even without amplification.
An excellent build quality.
The bass is noticeable more powerful than the mids, which is actually expected in V-shaped earphones.
The pre-applied tips are too soft and not grippy. Also, they are quite heavy to wear, so you'll need high quality tips to hold them firmly.
Lows / Bass
Massive beefy bass, with plenty of rumbling sub-bass filling the virtual soundstage. Perfect for electronic music.
Mids / Vocals
As expected, the mids take a backseat as with most V-shaped sound signatures, but the vocals are pretty accurate. Even if these earphones are more suitable for electronic music, you'll still enjoy vocals and acoustic instruments.
Highs / Treble
Crisp and sharp, even if slightly darkened by the bassy sound signature and there's no unordinary microdetail. Still, it's comfortable and enjoyable.
