Haylou PurFree BC01 review: Price and availability

The Haylou PurFree BC01 are available in black and pink colour options. In bone conduction headphone terms, they are among the most affordable modles I've seen. You can buy them directly from the Haylou website for $119 / £99, making them cheaper than the Shokz OpenRun Pro and Shokz OpenRun priced at $179 / £159, and $129 / £129 respectively.

They can also be found at online retail outlets. We've regularly seen them discounted to $85 at Amazon, and even go as low as $79. 

Haylou PurFree BC01 review: Design and comfort

The PurFree BC01 adopts a pretty familiar wraparound design that’s made from titanium and silicone to make sure they sit light and comfortable when they’re on and they certainly do that. They weigh just 0.98 ounces (around 28g), so they’re up there with some of the lightest bone conduction headphones. I’ve had no problem wearing them with glasses or a cap and they’ve been comfortable to wear for long periods during the day as well.

It’s always nice to see physical buttons and there’s three in total here. Two volume ones sit on the underside of the right arm, with the charging port sat alongside it. Over on the left is a larger button dedicated to playing and pausing audio, skipping tracks, launching your phone’s smart assistant and dealing with calls. The buttons are well positioned, easy to navigate when you’re stationary and on the move.

That ability to take calls does mean there’s microphones included and Haylou uses a dual microphone array with a cVc noise canceling algorithm that’s included to detect background sounds and reduce them when you need to make a call indoors or outdoors.

To make them fit for exercise Haylou uses a design that has an IP67 waterproof rating, which doesn’t mean they rank among the best waterproof headphones for swimming, but does mean they can handle both sweaty and rainy downpours.

Haylou PurFree BC01 review: Sound and call quality

There are some not so desirable characteristics that are associated with bone conduction headphones. They’re generally not going to be as powerful and bassy as the best wireless earbuds or the best headphones for starters. They do also tend to leak a lot of sound and don’t always give you the scope to customize the tonal balance. Nevetheless, the PurFree BC01 manage to strike a good balance and do a very good job.

Haylou says you can expect ‘premium sound quality’ and while that’s certainly a bold claim, these definitely sit at the more enjoyable end of the bone conduction spectrum. I used these headphones in a variety of scenarios. At my desk working, in the gym and out on runs, on public transport and generally just out walking with them. I listened to a mix of podcasts, my own bassy-heavy workout playlists and the useful Songs To Test Headphones playlist on Spotify (or even the Tom's Guide Headphone Demo playlist), which offer a nice range of tracks to see how the headphones can handle different music genres.

My overall feelings of the sound is that it’s bright, pretty versatile and in bone conduction terms has a very pleasant quality to it. On bass-heavy tracks like Burial’s "Archangel", they deliver a punchy and ever so slightly murky bass performance. Mids can feel slightly boxy, and treble a touch harshly, but it’s a mostly enjoyable. Slowing things down with Otis Redding’s "(Sittin’ On) the Dock of the Bay" and vocals sound pleasantly reproduced and they feel at ease on something less bass-centric in general.

Sound leakage is a big problem for bone conduction headphones. Though the Haylou aren't the worst offenders out there, you wouldn’t want to use them in quieter public spaces if you don’t want others to hear your playlists.

Things are a little better on the call quality front where I found performance strong for overall clarity, particularly in slightly louder environments, walking near roads and busier streets. Although the Halou don't rank among the best headphones with a mic for taking calls, they worked perfectly fine to use for calls both indoors and out and kept background noise to a minimum.

Lastly, multipoint sharing worked well and paired with my iPhone 14, MacBook Air, and a Garmin Epix Gen 2 sports watch without issue. 

Haylou PurFree BC01 review: Battery life

The Haylou PurFree BC01 bone conduction headphones promise a battery life of around 8 hours. Charging it takes around 1.5 hours to get a full battery.

Hitting that 8 hour battery mark is absolutely achievable. Even if you are running low, there’s a fast charging mode that gets you up to 2 hours of playtime with just a 10-minute charge. 

Battery prompts are delivered when you turn the headphones on. They’re pretty vague, and it would be far more useful if they indicated the battery percentage to give a sense of when they’re in need of charging.

Haylou PurFree BC01 review: Verdict

The Haylou PurFree BC01 deliver enjoyable sound whether you choose to exercise with them or use them for taking calls. They’re comfortable to wear for long periods, have really solid battery life and can rival the sound performance of bone conduction headphones costing more.
