The TECKNET Bone Conduction Headphones sit at number 8 in this guide at £28.99, rated 4.4 out of 5 from 283 ratings. They are over-ear bone conduction headphones with 16.7mm drivers, a retention strap for running and cycling, IPX5 water resistance and Bluetooth 6.0 — and they are the entry in this list whose battery figure survives being read literally.

Every other "40-hour" headline here is two numbers added together: a single-charge time plus a case. TECKNET does not do that. Its bullet says 10 hours of music playback on one charge from a built-in 220mAh battery, and the box contents field lists the headphones alone, so there is no case total to add on. The same bullet mentions "about 2 hours", which is the Type-C charging time rather than listening time — worth separating, because the listing puts both numbers in one sentence. Everything on this page comes from the Amazon listing for the TK-HS42, not from testing we have carried out ourselves.

## Questions people ask

**How long do the TECKNET TK-HS42 headphones run on one charge?**

The listing states 10 hours of music playback from the built-in 220mAh battery. No case or second battery appears in the box contents, so 10 hours is the whole figure rather than half of a bigger one.

**What is the "about 2 hours" in the battery bullet?**

It refers to charging, not listening. Type-C charging with the waterproof cover in place takes about 2 hours; the 10 hours is playback on a single charge.

**Can I swim in them?**

No. TECKNET rates them IPX5, described as resistance to sweat during exercise and everyday rain, and the listing states they are not suitable for swimming or prolonged immersion in water.

**What is in the box?**

The Box Contents field lists "Bone Conduction Headphones" only. No case, cable or ear tips are named there.

**How do they connect?**

Bluetooth 6.0 with a 10-metre range, pairing with mobile phones, tablets, laptops and computers. The listing gives no wired option and the headphone jack field says "No Jack".

**The page shows 283 ratings but the star bars add to 100 — why?**

The bars are the percentage split, not a count: 70% five-star, 15% four-star, 8% three-star, 4% two-star and 3% one-star across the 283 ratings. The 4.4 average comes from that split.
