If you want a neckband-style open-ear set built for long, comfortable wear on the bike with dual-mic call clarity, choose Purity Air Open Ear; if you need maximum runtime, a bendable titanium frame and a higher waterproof rating for sweaty rides and light rain, choose QAZITV Bone Conduction Headphones.
• Purity Air Open Ear — biggest strength: air-conduction drivers (two 15mm dynamic drivers) plus dual microphones with environmental noise cancellation for calls, in a lightweight neckband design (2.8 oz) that hangs behind the neck.
• Purity Air Open Ear — biggest trade-off: the lowest rated battery of the two at 6 hours, and IPX5 water resistance rather than the higher IP65 rating of its rival.
• QAZITV Bone Conduction Headphones — biggest strength: long battery life (9 hours average, 8–10 hours claimed) with a 2-hour Type-C charge, a 25g bendable titanium frame, and IP65 waterproofing.
• QAZITV Bone Conduction Headphones — biggest trade-off: bone conduction sound sits on the cheekbones rather than in the ear, so bass and isolation behave differently than a driver-based design, and it runs Bluetooth 5.0 instead of 5.3.
• Who each pick is for: Purity Air Open Ear suits the rider who wants a comfortable neckband, clear calls, and doesn't mind charging more often; QAZITV suits the rider who wants endurance, a flexible fit, and tougher water resistance.
The Purity Air Open Ear is a neckband open-ear headphone built around air conduction. Two 15mm dynamic drivers sit at the ends of a band that hangs behind your neck, and the speakers rest against your ears rather than plugging into them. That open design is the whole point for cycling: you get your music or podcast while your ears stay open to traffic, bells and the general noise of the road. If you ride in mixed traffic or on shared paths, that awareness is not a gimmick, it is the reason to pick an open-ear set at all.
The fit story is comfort-first. At 2.8 ounces it is light, and the neckband layout means the weight is carried behind your head rather than pressed onto your ears. For long rides, commutes or all-day wear, that is a genuinely different feeling from clamping earbuds in place. The IPX5 rating covers sweat and splashes, which is exactly the exposure a cyclist generates, though I would not treat it as a swim or heavy-rain rating.
The other half of the appeal is calls. Dual microphones with environmental noise cancellation are aimed squarely at talking while you ride or work, and that is where this design earns its keep over a plain music-focused set. The trade-offs are honest ones: 6 hours of battery per charge means you will top it up more often than the QAZITV, there is no active noise cancellation here, and charging is via a magnetic cable rather than a standard port. Buy it if comfort, call clarity and open-ear awareness matter most. Skip it if you need the longest possible runtime or the toughest water resistance.
The QAZITV Bone Conduction Headphones take a different route entirely. Instead of firing sound at your ear, they sit on your cheekbones and transmit vibration through bone to your inner ear. The practical effect for a cyclist is the same open-ear awareness, but the mechanism changes the feel: nothing enters your ear canal, which some riders find far more comfortable over hours in the saddle, and it keeps the ear canal clean and irritation-free.
The frame is the standout spec. It is titanium, it weighs about 25 grams, and it is described as bendable and tough, springing back into shape. For cycling that matters twice over: the low weight means you forget you have it on during a long ride, and the wraparound earhook design is meant to stay put through high-intensity efforts rather than sliding around when you sweat. The IP65 waterproof rating is the highest of the two here, rated to withstand sweat and light rain, which is a meaningful edge for anyone riding in changeable weather.
Battery is where it pulls clearly ahead. The 200mAh cell is rated for 8 to 10 hours of playback (9 hours average) from a 2-hour Type-C charge, so a week of commuting on a single charge is realistic for many riders. It also supports multi-point connection, so you can stay paired to a phone and a laptop and switch between them without re-pairing each time. The trade-offs: Bluetooth 5.0 rather than 5.3, push-button controls instead of touch, and because it is bone conduction, deep bass and passive noise blocking are not its strengths. Buy it if battery life, a flexible secure fit and water resistance top your list. Skip it if you specifically want a neckband feel or a driver-based sound signature.
• Best battery life → QAZITV Bone Conduction Headphones (9 hours average, up to 10 claimed, vs 6 hours).
• Best for call clarity on the move → Purity Air Open Ear, thanks to its dual microphones with environmental noise cancellation.
• Best for sweat and light rain → QAZITV Bone Conduction Headphones with IP65, versus IPX5 on the Purity.
• Best for long-wear comfort on a neckband → Purity Air Open Ear, at 2.8 oz with a behind-the-neck layout.
• Best for a flexible, secure wraparound fit → QAZITV Bone Conduction Headphones, with its bendable 25g titanium frame.
• Best for newer Bluetooth → Purity Air Open Ear (Bluetooth 5.3 vs 5.0), which generally means a more current connection standard.
• Best for switching between devices → QAZITV Bone Conduction Headphones, which supports multi-point connection.
• Best for a driver-based sound with larger drivers → Purity Air Open Ear (two 15mm dynamic drivers vs a bone conduction driver).
• Best for charging convenience → QAZITV Bone Conduction Headphones, with standard Type-C charging versus the Purity's magnetic cable.
If I had to pick one for cycling, I would buy the QAZITV Bone Conduction Headphones. In my opinion the combination of 8–10 hours of battery, a bendable titanium frame that stays put during hard efforts, and IP65 water resistance is the most useful package for real rides, where sweat and weather are constant and charging is a chore. It is not perfect: Bluetooth 5.0 is older and bone conduction won't give you the fuller driver-based sound of the Purity. But if call quality and comfort are your priorities instead, the Purity Air Open Ear is the smarter buy. Check the current price on Amazon for both before you decide.
Both are open-ear designs that keep you aware of traffic, which is the key cycling benefit. QAZITV edges ahead on battery (9 hours vs 6) and waterproofing (IP65 vs IPX5); Purity edges ahead on call clarity and a lightweight neckband fit.
QAZITV. It is rated for 8 to 10 hours (9 hours average) from a 2-hour Type-C charge. The Purity Air Open Ear is rated at 6 hours, so it needs charging more often.
The QAZITV is IP65 rated, so it handles sweat and light rain. The Purity Air Open Ear is IPX5, which covers sweat and splashes. Neither is designed for swimming.
Open-ear sets trade some bass and isolation for awareness and comfort, so the sound signature is different rather than strictly worse. The Purity uses two 15mm dynamic drivers; the QAZITV uses bone conduction, which some riders prefer for long-wear comfort.
Value depends on what you need most: QAZITV for battery, water resistance and a flexible fit, Purity for call clarity and a light neckband. Compare the current prices on Amazon before deciding.
