Sound Description & Battery Life

Although it supports aptX high-definition sound quality, bone conduction headphones are not born for music, so they are inferior to in-ear earbuds in terms of sound quality. But Haylou PurFree has done a good job in this regard, even at the maximum volume, there is no sound breakage or sound leakage. The low-frequency extension is ok, the mid-frequency vocals are relatively clear, and the high-frequency musical instruments have a good sense of layering and ductility.

People buy bone conduction headphones mostly for outdoor or sports scenes, so in the audition session, I chose some songs that are suitable for listening to while exercising. In terms of listening sense, you can feel the concentrated sound and full tone brought by Haylou PurFree. When listening to songs like “Enemy”, “Believer” and “Radioactive” by Image Dragon, it’s easy to get people moving with the rhythm of the music, which can bring you more fun while working out.

In order to achieve these effects, Haylou PurFree uses Directional audio technology to make the sound more concentrated, while deepening the extension of the low frequency. In addition, the sound unit is a 360° closed sound cavity, which effectively avoids sound leakage, protects privacy, and avoids embarrassment.

Haylou PurFree has a battery life of up to 8 hours in a single session, which can accompany you to run a marathon. If you exercise for an hour a day, you can charge it once a week. And 20 minutes of charging can be used for 2 hours. It can be fully charged in 1.5 hours, and the experience is very convenient and fast.
