Another interesting find by a brand that does unfamiliar but high quality audio equipment - Winintone. I picked the stunning RG-EB601 and managed to buy it on AliExpress just before it went out of stock. However, it seems you can still get them from eBay.
These earphones are not just well-built and premium-looking, they are also good-sounding. The sub-bass is pounding and the mid-bass is thick and full. The mids are crisp, but slightly overpowered by the sharp highs. The volume levels are high even on low-power sources.
This review focuses on the silver filters, because the black filters sound the same and the golden filters sound pathetic.
The filters included with KZ ED9 can also be used with these earphones for additional sound signatures.
The filters included with KZ GRcannot be used with these earphones, but you can use the filters included with these earphones with KZ GR.
A brilliant sound quality. The bass is massive (as long as you have a perfect seal), the mids are loud and clear and the highs are energetic.
Very premium design and materials. The build quality is superb.
The vocals get slightly pushed back and get sibilant because of the peaks in the high frequencies.
Since there is no inline remote, it's difficult to differentiate between left and right channels. The only instant way is by checking the R and L markings on the strain reliefs.
The 3.5mm plug is long, which makes you worry about not breaking it by accident.
No proper retail packaging.
Package & Accessories
Ear Tips - Single-Flange:
S+M+L, grey (translucent), Ø4mm red bores
Silver (bassy signature)
Black (bassy signature)
Golden (bassless signature)
The black filters sound just like the silver filters, and the golden filters are simply useless and won't be analized further.
The included tips don't offer a proper seal for me. ROCK Zircon's tips made things more comfortable and even sound much better, since wide-bore tips are much more suitable for these earphones.
Lows / Bass
The bass is quite deep, precise and controlled, but doesn't go too deep on the sub-bass range, unless you have some EQ involved. Still, the fact that it doesn't get distorted on higher volumes, and that it's so punchy and precise is more than enough.
Mids / Vocals
The mids are clear, loud and tonally precise. However, they tend to get pushed back by piercing highs. Sibilance is quite normal with these earphones on above-medium volumes.
Highs / Treble
The highs are sharp and quite enjoyable, but their peaks are quite noticeable when vocals get slightly sibilant.
