Blitzwolf BW-ES2 | Budget Dual Dynamic Driver
Our first Blitzwolf IEM for review and this has dual 6mm Dynamic driver on each side. All black matte finish with a semi-transparent bit to show the dual dynamic drivers. Sound isolation is good, especially people are talking in noisy bus ride, that sound pollution is halved.
The cable is 1.2 meters long, untangling can be a nightmare so they provided the cable organizer to keep it tidy. The control center house the mic, volume rocker, media playback/call function. It comes with total of 3 ear-tips sizes and small hard carrying case, not bad for a budget buds. Weighs 17 grams since it mainly made out of plastic. For the microphone test do watch our review video, but is good for the price.
- Sensitivity 108 ± 3dB
- Impedance 16Ω
- Frequency Response 20Hz – 40,000Hz
Our test usually uses the iPhone 6 at the 5th volume bar but we had to bump to to the 7th volume to fully get its potential, for some reason it need more power to drive it. Not a great start.
Tiaan – Be Okay
Low bass frequency slightly overpowered (minor distortion felt), super energetic (too much), pressure is booming in the ears. I strongly advice hearing at a lower volume to prevent ear fatigue.
Pia Mia – Do It Again
Bass energetic, vibrations can be felt easily and fades little quickly for my liking. Doesn’t eat into the vocals.
Violinder – Raindrops
Violin/Piano tones are okay tho it feels safe, like it doesn’t try to to add more shine into the highs. The Bass/Drum does overpower the Violin/Piano tones.
Ed Sheeran – Touch and Go
Guitar tone is safe feeling but okay, lacks a bit of shine at the highs, vocals performs well. Guitar vibration can be heard but softly.
This dual dynamic driver is suited for bassy song, vocals is do-able but not the best. Is more for POP/EDM/Electronic songs, think of it as a baby JVC twin driver IEM just much cheaper and need more refinement to sound better.
