If you want studio-grade wired flexibility with marathon battery life, choose OneOdio A70; if you need a low-latency gaming headset that juggles console, PC and Bluetooth at once, choose RK ROYAL KLUDGE HG101. These two over-ear headphones look similar on paper — both run 40mm dynamic drivers at 32 ohm — but they are built for completely different desks. One is a hybrid wired/wireless studio tool. The other is a triple-mode gaming headset. Here's how to tell which one belongs on your head.
• OneOdio A70 — biggest strength: hybrid wired and wireless design with both 3.5mm and 6.35mm jacks, 72-hour battery life, Bluetooth 5.3, and a foldable, rotatable over-ear frame.
• OneOdio A70 — biggest trade-off: it relies on passive sound isolation rather than active noise cancellation, and its Bluetooth spec is a generation behind the HG101's.
• RK ROYAL KLUDGE HG101 — biggest strength: three connection modes in one headset (2.4G USB adapter, Bluetooth 6.0, and wired 3.5mm/USB-C), plus 7.1 surround sound, RGB side strips and a retractable mic.
• RK ROYAL KLUDGE HG101 — biggest trade-off: its listed battery charge time is just 2 hours with no rated playtime figure, and it leans hard into gaming aesthetics rather than neutral studio looks.
• Who each pick is for: the A70 suits musicians, producers and anyone who needs wired monitoring plus wireless freedom; the HG101 suits gamers juggling a console, a PC and a phone.
The A70 is, in my read of the spec sheet, a studio headphone that happens to be wireless. That hybrid identity is the whole point. You get Bluetooth 5.3 with a 10-meter range for everyday listening, but you also get a 3.5mm jack and a 6.35mm jack — the larger one being the standard plug for amps, mixers and audio interfaces. If you play guitar, monitor a mix, or plug into a PC's headphone port, that dual-jack arrangement is the feature you'll actually feel every day.
The battery story is the standout number: a rated 72 hours of average life on a 72-hour charge time. Whether that's a full week of commuting or several long studio sessions, it means charging becomes an afterthought rather than a ritual. The 40mm neodymium drivers, 32 ohm impedance and 20 Hz–40 kHz frequency range suggest a tuning aimed at full-range detail rather than a boosted gaming curve, and the 110 dB sensitivity means it should get loud from modest sources.
Comfort and portability are clearly designed in. The over-ear frame rotates and folds, the cushions use memory cotton with protein leather, and the whole thing weighs 8.96 ounces — light enough for long wear. There's also a genuinely unusual feature: audio sharing. Pair the main headphones, then run a cable out to a second pair so two people can watch or play together. The built-in mic with noise reduction handles calls.
Buy the A70 if you want one headphone for wired studio work and wireless listening, you value battery life above almost everything, or you need the 6.35mm amp connection. Skip it if you want active noise cancellation, a boom mic for competitive voice chat, or surround-sound processing for gaming.
The HG101 is the opposite philosophy: one headset, every gaming platform. Its defining trait is triple-mode connectivity. A 2-in-1 2.4G USB adapter delivers low-latency, lossless audio to PS4, PS5 and Switch — the kind of near-instant response that matters when you're reacting to footsteps. Bluetooth 6.0 covers the 10-meter wireless case for phones and laptops, and there's a wired path too, via 3.5mm or USB-C. That's three ways to connect without swapping hardware.
The audio side is tuned for games. The 40mm drivers are paired with 7.1 surround sound processing so directional cues — footsteps, callouts, reloads — come through with spatial placement. The 120 dB sensitivity is notably higher than the A70's 110 dB, which in practice means it should reach loud volumes easily from weaker sources like a controller's headphone jack. RGB strips on the sides round out the aesthetic; this is a headset that wants to be seen.
For voice, the HG101 uses an omnidirectional mic that retracts into the housing when you're not talking. That's a small design decision with real payoff — no boom arm dangling in your peripheral vision during solo play. The mic also reduces background noise for chats. Comfort is handled with a padded adjustable headband and memory foam cushions, and the box includes the 2-in-1 wireless receiver, a USB-A to USB-C charging cable, a USB-C to 3.5mm audio cable and a manual.
The trade-offs are worth naming honestly. The listed charge time is 2 hours with no rated playtime figure, so I can't tell you how long a session lasts — that's a real unknown compared to the A70's explicit 72 hours. Noise control is environmental noise cancellation rather than full active ANC. And the styling is unapologetically gamer-forward.
Buy the HG101 if you game across console and PC, want 2.4G low-latency audio, and like surround processing and RGB. Skip it if you need amp-ready 6.35mm monitoring, guaranteed long battery life, or a neutral look for an office.
• Best for battery confidence → OneOdio A70. A rated 72 hours of average life versus an unspecified playtime on the HG101.
• Best for gaming latency → RK ROYAL KLUDGE HG101. The 2.4G USB adapter exists specifically to cut wireless delay on PS4, PS5 and Switch.
• Best for studio and instrument work → OneOdio A70. The 6.35mm jack is the deciding detail; the HG101 only offers 3.5mm.
• Best for platform coverage → RK ROYAL KLUDGE HG101. 2.4G, Bluetooth 6.0 and wired in one unit.
• Best for voice chat while gaming → RK ROYAL KLUDGE HG101. Retractable omni mic with noise reduction beats a general-purpose built-in mic for team comms.
• Best for Bluetooth headphones on a PC → it depends on your PC's setup. If your desktop lacks Bluetooth, the HG101's USB adapter sidesteps the problem entirely.
• Best for shared listening → OneOdio A70. The audio-sharing cable feature has no equivalent on the HG101.
• Best for newer Bluetooth → RK ROYAL KLUDGE HG101. Bluetooth 6.0 outranks the A70's 5.3.
If I were buying for myself, I'd take the OneOdio A70. The 72-hour battery rating, the 6.35mm jack and the foldable hybrid design cover more of what I actually do — listen wirelessly, then plug into an amp or interface without hunting for an adapter. The HG101 is the better pick only if gaming is your primary job and you want that 2.4G low-latency link with a retractable mic. Different tools, different desks. In my opinion, the A70 is the more versatile headphone for the average buyer.
how to connect bluetooth headphones for pc
On Windows, open Settings, go to Bluetooth & devices, turn Bluetooth on, then choose "Add device" and select your headphones from the list. The A70 uses Bluetooth 5.3 and the HG101 uses Bluetooth 6.0, both with a 10-meter range. If your PC has no Bluetooth radio at all, the HG101's 2.4G USB adapter is the simpler route.

Once paired, set the headphones as the default output in your sound settings. For calls, pick them as both output and input device so the mic is active. The A70's built-in mic handles calls, while the HG101's retractable omni mic is better suited to game chat.

Put the headphones in pairing mode, then add them through your operating system's Bluetooth menu — Windows, macOS and most Linux desktops all follow the same pattern. Keep the headphones within 10 meters during pairing, which is the rated wireless range for both models. Reconnecting later is usually automatic.

If pairing fails, remove the old entry from your device list, restart the headphones, and try again. Both headsets support wired fallback — 3.5mm on both, plus 6.35mm on the A70 — so you can keep listening while you troubleshoot. For consoles like PS5 or Switch, the HG101's 2.4G adapter is often the more reliable connection than Bluetooth.
