4.0/5.0

The new VJJB flagship - the K4/K4S - which take the brand to a more mainstream direction when it comes to sound. These earphones are near perfection when it comes to sound quality, especially if you appreciate fat, beefy bass with throbbing sub-bass. Perfect for bass-heavy electronic music, but not limited to it. It actually sounds amazing with other genres as well.

The build quality and use of materials is amazing, as usual with VJJB products.

Pros

  • Excellent sound quality overall. The bass is unbelievable, the mids are decently precise and the highs are comfortably tuned.

  • A superb design and use of materials.
  • A great package, good looking carrying pouch and a decent variety of ear tips.

Cons

  • The sub-bass can overwhelm the mids sometimes.
  • It was difficult to keep a good seal with them, but your mileage may vary.
  • Incompatible with wide-bore ear tips due to narrow nozzles.

Comfort & Fit

I had troubles keeping a good seal for a long time with the included tips, probably due to the narrow nozzles. The best tips seemed to be the pre-applied foam tips.

Lows / Bass

Massive bass response, as long as you have a perfect seal. The sub-bass is very deep, you can actually feel it very well inside the ear canals. There's a lot of energy and excitement in the sound thanks to the thumping bass.

Mids / Vocals

Warm, surrounding, energetic and very loud. Mostly neutral but could seem slightly darkened, especially on female vocals. Not superbly detailed but still quite excellent.

Highs / Treble

The highs are loud and crisp, sometimes might be slightly sibilant. They are somewhere between neutral and mildly darkish, but on the detail level - there isn't too much microdetail involved, just the usual highs you can hear mainly on V-shaped earphones.
