What to know before buying

The product is described as IPX6 and suitable for sweat, with swimming explicitly excluded.

Listing details to confirm

The title claims noise cancelling, but the specifications list noise control as “None” and the description discusses environmental noise reduction for calls. Treat noise cancellation as unconfirmed, and do not assume music playback is isolated from surrounding sound. Weight is inconsistent in the listing: the details state 20 Grams, while feature copy claims 160g/0.35lb. Battery-use and charging claims appear in promotional copy, not the technical inventory. The listing also alternates between one-button and touch controls, so confirm the details for the selected listing before purchase.

Customer feedback highlights sound and comfort, with some customers describing good value. Experiences are mixed on durability, noise reduction and connectivity, and charging draws criticism. These concerns are relevant for exercise use and frequent charging. The listing does not establish noise cancellation for music, and its weight and control details are inconsistent, so those claims should be treated separately from customer impressions.

Positive themes

Customers report good sound and comfortable wear.

Negative themes

Charging receives criticism, including a report of a very short proprietary cable.

Mixed feedback

Durability feedback is mixed, with reports of both satisfactory use and headphones stopping after a few weeks.
Noise reduction feedback is mixed. The supplied feedback distinguishes limited effect on surrounding noise from how audible the headphones are to nearby people.
Connectivity feedback is mixed, including a reported USB-C compatibility issue.

Frequently asked questions

Are the Ulian BH831 bone-conduction headphones?

No. The listing identifies them as air-conduction headphones and explicitly says they are not bone-conduction headphones.

Can these headphones be used for swimming?

The listing claims IPX6 protection for sweat and says not to use them for swimming.

How long does the battery last?

Promotional copy claims up to 8.5 hours of music or call use and up to 110 hours on standby. These are listing claims, not independently verified results.

Do they cancel surrounding noise?

That is unclear. The title claims noise cancelling, but the specifications state “None” for noise control. The description refers to noise reduction during calls, so buyers should not assume music noise cancellation.
