Blitzwolf BW-BTS1 Review | IPX4 Sport Bluetooth Earphone
This is Blitzwolf’s sport IEM featuring IPX4 water and sweat resistances as well as magnetic ends. The package comes included with a hard carrying pouch, a charging cable, a shirt clip, a cable management tab, 3 pairs of earfins and 3 pair of eartips. The earfins with the cable management tab does perform well for gym activities and high intensive movements.
The controller is located on the right side and it houses the charging port, microphone and the typical 3 array buttons. The buttons does have a tactile bump and are easy to actuate. Sound isolation is good as it blocks a good amount of environmental noise.
It uses Bluetooth 4.1 for connectivity and the maximum stable line of sight is 11 meters. The rated battery life is 8 hours. Our battery life test is based on the iPhone 6 at 2nd volume bar, it lasted us 9 hours 15 minutes. It supports APT-X lossless codec.

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 vibrations fades smoothly. Low bass frequency is is well bodied The low bass overpower the vocals but not in a huge amount, just slightly.
Pia Mia – Do It Again (standard bass)
Bass is highly energetic and highly notable, you can feel the air pressure. The bass fades butter-smooth at the 2:05 mark. Bass doesn’t overpower vocal much, just tiny bit and there is a clear separation between the two. Bass is well bodied. EDM tones sounds exciting and fun.
Violinder – Raindrops (high frequency instrumental)
Piano/Violin tone sounds right and natural, leans closer to the crystal-clear type not the warm-sound, I prefer crystal-clear type. It has right amount of shine at the highs. Tones are well bodied and doesn’t sound half-hearted. Bass/Drums overpowers the Piano/Violin just a tiny in term of audible levels, tho there is clear separation between the two.
Pentatonix – See Through (high frequency vocals / vocal separation)
Mitch Grassi’s hi-pitched-male Tenor vocals perform very well at the highs with the right amount of shine, feels bright. Each singer can be identified easily. Every diction and pronunciation is crystal clear. Vocal beatboxing, echoing and humming is eargasm, but does slightly overpower Mitch Grassi’s vocal in the song.
The IEM performs well from lows to highs but it’s core strength lies in the mids to highs. The best sport IEM model under the blitzwolf so far that we review beating the old version, they improved the audio game this time
