ø8mm Dynamic Driver


The M001 model by HZSOUND is, as it seems, a rebranded and slightly redesigned (specifically the Y-split and the plug and the added cinch) version of Winintone RG-EB601. However, they also modified the sound signature a bit and solved RG-EB601's biggest issue - overemphasized peaks in the highs. M001's peaks are more subtle which greatly limits most instances of sibilance!

Just as I said about RG-EB601, these earphones are both well-built and premium-looking, and are also good-sounding. The sub-bass is pounding and the mid-bass is thick and full. The mids are crisp, and the highs only marginally sharp. The loudness is high even on low-power sources.

This review focuses on the silver filters, because the black filters sound pathetic.

Sound signature: V-shaped



  • A brilliant sound quality. The bass is massive, the mids are loud and clear and the highs are energetic.
  • Very premium design and materials. The build quality is superb.
  • The cable comes perfectly straight out of the box. Well done, HZSOUND.


  • The vocals are still slightly pushed back and the highs could use some extra definition and detail.
  • The black filters are simply useless.

Comfort & Fit

With the included tips, you might have to push these earphones deeper than you usually would. consider trying different, preferable wide-bore tips for a better seal and some extra detail in the highs. Overall, these earphones are very comfortable and there's nothing wrong with their shape or weight.

Lows / Bass

The bass is very deep, precise and impactful. It doesn't get distorted on higher volumes, and you can even feel slight vibration when there's deep sub-bass content playing. It's like having a night-club in your ears, amazing.

Mids / Vocals

The mids are clear, loud and tonally precise. However, they are pushed back just a tiny bit and there could be a bit of sibilance on above-medium volumes. These are very normal for V-shaped earphones and the impressive tonal accuracy is much more imporant as far as I'm concerned.

Highs / Treble

The highs are sharp and very enjoyable, their peaks are quite noticeable and there might be slight sibilance now and then. These earphones are some of the best V-shaped earphones on the market, if that's your thing. Very energetic highs with a huge fun-factor.
