Rank #8 in Best Open Ear Headphones 2026: 10 Ranked, and the 40-Hour Myth
TECKNET Bone Conduction Headphones, Bluetooth 6.0, IPX5
Price and rating as shown on Amazon when we collected them. Both change.
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.
