Comfort & Connectivity
Thanks to Haylou PurFree’s aviation-grade memory titanium wire skeleton, the weight is successfully controlled at 28g, and it feels very light and comfortable to wear. The swan-neck ear-hook contour features an ergonomic multi-point support design. I ran fast and jogging tests, and the Haylou PurFree hangs firmly on the ear without loosening due to shaking and so on.
The skin-like silicone on the surface of Haylou PurFree is very delicate to the touch, and it does not feel strange when it fits the skin, especially suitable for use in summer. The open way of use is very friendly to the ear canal, and it can be said that it will not feel uncomfortable when used for a long time.

And Haylou PurFree also supports dual device connection, and the practicability has also been improved.
Sound Quality & 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.
