This is Blitzwolf’s affordable ear-hook style sport IEM featuring IPX 5 water resistance.

The ear-hooks does hold the headpiece together during aggressive movement, the cable management tab is a lifesaver for running.

Audio quality

EDM/POP/SYN:

Tiaan – Be Ok (Low bass frequency)
Low bass frequency is superbly energetic and highly notable, you can feel the air pressure booming in your ears. It doesn’t eat into the vocals and has zero bass distortion. The subtle bass vibration fades smoothly. Low bass frequency is well bodied. The low bass slightly overpower the vocals.

Pia Mia – Do It Again (standard bass)
Bass has decent energy and presence, you can feel the air pressure. The bass fades butter-smooth with a long drag especially at the 2:05 mark, the vibrations is nice but bit softer. Bass doesn’t overpower vocal much and feel balanced in terms of audible levels, clear separation between the two. Bass is well bodied. Vocals slightly muffled. EDM tones sounds safe or laid back.

With and without the eartips

Vocals/Instrumentals:

Violinder – Raindrops (high frequency instrumental)
Piano/Violin tone sounds right and natural, leans closer to the warm-sounding type not the crystal-clear, I prefer crystal-clear type. Need more shine at the highs. Tone are well bodied doesn’t sound half-hearted.
 Bass/Drums feels balance with Piano/Violin in term of audible levels, bass slightly eat into the highs.

Pentatonix – See Through (High pitch vocals / group separation)
Mitch Grassi’s hi-pitched-male Tenor vocals perform borderline decent as it needs a lot of shine to sound sharp at the highs. Each singer can be identified easily. Every diction and pronunciation is clear. Vocal beatboxing, echoing and humming is good which doesn’t overpower Mitch Grassi’s vocal in the song. However vocals overall sound slight muffled.

This sport IEM performs well from the low bass frequency up to the mid frequency, if they improved the clarity and shine it can perform well at the upper mids. Again it work well as a sport IEM that stays in place during high intense workout and for bass head people.
