How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want vintage over-ear comfort with 60 hours of playtime and Bluetooth 5.4 multipoint, choose iKF R2; if you need an open-ear bone conduction design that keeps your ear canal free while you run, ride or work, choose QAZITV Bone Conduction Headphones. Both connect to two devices at once, but they solve completely different problems — one is a sit-down listening headphone with a retro soul, the other is a stay-aware sports headset you forget you're wearing.
• iKF R2 — biggest strength: a genuinely comfortable over-ear build (steel strip, leather headband, protein-skin cushions) paired with a 40mm dynamic driver and a claimed 60 hours of playtime on one charge.
• iKF R2 — biggest trade-off: it's a closed over-ear design, so it blocks your surroundings and it's not built for heavy sweat or rain; the 0.32 kg weight is real on long walks.
• QAZITV — biggest strength: open-ear bone conduction that leaves your ear canal uncovered, a lightweight 30 g ear-hook frame, and an adjustable noise-canceling boom mic for calls.
• QAZITV — biggest trade-off: battery life is far shorter (8 hours claimed, 10 hours listed in the battery specs), and bone conduction bass simply can't match a 40mm dynamic driver.
• Who each is for: pick iKF R2 if you want immersive over-ear sound, long battery life and a retro look for commuting, office and gaming. Pick QAZITV if you want situational awareness, hygiene and a secure fit for running, cycling and workshop-style work.
The iKF R2 is an over-ear Bluetooth headphone dressed in a brown, retro 80s/90s costume — metal accents, litchi-textured leather, a steel strip headband. That styling is the point for a lot of buyers, but the internals hold up too. A single 40mm NdFeB dynamic driver covers a 20 Hz – 20,000 Hz range at 32 ohm impedance, which is a standard, easy-to-drive configuration that suits music, films and games without any special equipment.
Where it really separates itself is endurance and connectivity. Bluetooth 5.4 with dual-device multipoint means it can hold a phone and a laptop at the same time and switch between them without re-pairing — genuinely useful if you take calls on your phone while working on a computer. The claimed 60 hours of playback (about a 2-hour charge) is the kind of figure that means you can stop thinking about charging for a week of normal use. There's also a 3.5mm jack and an AUX cable in the box, so you can keep listening wired when the battery is flat — a nice fallback that most modern headphones have dropped.
Buy it if you want one pair for commuting, desk work, calls and gaming, you value a warm retro aesthetic, and you'd rather charge once a week than once a day. Skip it if you need to hear traffic and coworkers around you, you train hard and sweat heavily, or you want something that disappears in a pocket — this is a 0.32 kg over-ear headphone, not a gym accessory.
QAZITV Bone Conduction Headphones: Who It's For
The QAZITV set takes the opposite approach. Instead of sealing a driver over your ear, it vibrates your temporal bone to send sound to the inner ear, leaving the ear canal completely open. That's the whole appeal: your ear stays clean and unblocked, and you keep hearing the world around you. For cyclists, runners and anyone working around machinery or traffic, that situational awareness is a safety feature, not a gimmick.
The frame is a black plastic ear-hook design weighing just 30 g, and QAZITV leans hard on comfort — open-ear ergonomics that, in their words, won't cause pain even after long wear. The controls are physical buttons (power, volume, multi-function), which is honestly a plus for sports use: you can find a button by feel with gloves on or with sweat in your eyes, no touch-surface guessing required.
For calls, there's an adjustable noise-canceling boom mic that swings toward your mouth, plus dual ENC microphones to suppress ambient noise. A boom mic positioned at your mouth is generally more reliable for voice pickup than a mic buried in the earcup, which is why this style shows up on work headsets. Connectivity is Bluetooth 5.2 with a 10-meter range, and it supports connecting to two devices at once — phone and Windows computer, for example — with seamless switching. Battery life is the compromise: 8 hours of playtime claimed in the features, 10 hours listed in the battery specs, from a 2-hour charge.
Buy it if you run, cycle, walk busy streets, or work a job where you need your ears open and your hands free, and you want a mic that actually picks up your voice. Skip it if you want deep bass and immersive isolation, you need all-day battery, or you mainly listen in loud environments where open-ear sound gets drowned out.
• Best for battery life → iKF R2. 60 hours claimed versus roughly 8–10 hours on the QAZITV.
• Best for sound quality and bass → iKF R2. A 40mm NdFeB dynamic driver at 32 ohm simply moves more air than a bone conduction driver at 8 ohm.
• Best for situational awareness and safety → QAZITV. The open-ear design never blocks traffic, voices or warning sounds.
• Best for sports and sweaty activity → QAZITV. At 30 g with an ear-hook fit, it's built to stay put; the iKF R2 is a 0.32 kg over-ear.
• Best for phone calls in noisy places → QAZITV. The adjustable boom mic sits at your mouth, backed by dual ENC mics.
• Best for gaming and low-latency audio → iKF R2. Its 35ms low-latency mode is designed for real-time sync.
• Best for wired backup and travel → iKF R2. The 3.5mm jack and included AUX cable mean it works even with a dead battery.
• Best for ear hygiene and long wear without pressure → QAZITV. Nothing enters or covers the ear canal.
Both support Bluetooth multipoint, so if connecting to two devices at once is your deciding factor, either one clears that bar — the question is what you're doing while you wear them.
If I had to buy one, I'd take the iKF R2. In my opinion, the combination of Bluetooth 5.4 multipoint, 60 hours of playtime, a 40mm driver, ENC calling, a 35ms game mode and a wired fallback makes it the more versatile headphone for the way most people actually use audio — commuting, working, calls and gaming in one pair. The QAZITV is the better tool for a narrower job: running, cycling and staying aware of your surroundings. If that's your daily reality, buy the QAZITV instead. Otherwise, the iKF R2 covers more ground.
what is multipoint bluetooth headphones
Multipoint Bluetooth is a feature that lets one headphone hold active connections to two devices at the same time — for example a phone and a laptop — and switch between them without pairing again. Both the iKF R2 (Bluetooth 5.4) and the QAZITV (Bluetooth 5.2) support this dual-device connection.
can bluetooth headphones connect to multiple devices
Yes, if they support multipoint. The iKF R2 connects to two devices simultaneously and lets you switch between music, calls and games, and the QAZITV can connect to two devices at once with seamless switching. Without multipoint, a headphone can usually only be paired to one device at a time.
which headphones have bluetooth multipoint
In this comparison, both do. The iKF R2 lists dual-device connection on Bluetooth 5.4, and the QAZITV lists multi-device connection on Bluetooth 5.2. If multipoint is a must-have for you, either one qualifies — the real difference is battery life, fit and sound style.
do bone conduction headphones sound as good as over-ear headphones
Not in the same way. Bone conduction sends sound through your temporal bone and leaves the ear canal open, so bass and isolation are limited by design. The iKF R2's 40mm dynamic driver produces fuller, more immersive sound, while the QAZITV's advantage is awareness, comfort and hygiene rather than audio depth. Choose based on which of those you value more.
