KZ GR

ø10mm Dynamic Driver

$5~$10
1.5/5.0

There was some hype among budget earphone enthusiasts about these earphones, so I had to see what the hype is all about. I still don't understand. Good looking earphones that sound below avarage. No detail precision at all. The vocals and highs are overemphasized and harsh, very painful to listen to.

NOTE: The filters included with KZ ED9 and Winintone RG-EB601 can also be used with these earphones for additional sound signatures.

Pros

  • Nice bass response, but not extraordinary.
  • A pretty good build quality.

Cons

  • Excessively loud and unclear mids and highs. Very sibilant vocals.
  • Whether you get the retail box or not, you won't like it either way. The included tips are cheap and dust sticks to them all the time.

Package & Accessories

Package:

Corrugated fiberboard

Ear Tips - Single-Flange:

S+M+L, black, ø4mm bores

Filters*:

Black (bassy signature)

Red (bassless signature)

  • The red filters are simply useless and won't be analized further.

Build & Materials

Housings:

Metal, ø6mm switchable nozzles (ø3mm openings), soft strain reliefs

Y-Split:

TPE, soft strain reliefs

Cable:

Silicone-coated (smooth), 113cm, soft, straight

Plug:

TPE, 90° angled, long, soft strain relief

Comfort & Fit

The GR are quite heavy so even if you have well-fitting tips, they still might fall out. Also, they are long because of the filters, so they stick out of your ears.

Lows / Bass

With the black filters, the bass is actually pretty good, slighty punchy but nothing extraordinary. With the red filters, the bass is absent completely.

Mids / Vocals

Loud but has no clarity. Inaccurate tone with a lot of sibilance with both filters, maybe slightly better with the [otherwise useless] red filters.

Highs / Treble

Can be painfully piercing with both filters but it's never accurate, not even close to being accurate. Very fatiguing.
