If you want a console-and-PC-style low latency earbud with active noise cancelling and a dongle that lives in the case, choose Amazon Renewed JBL Quantum TWS; if you need a plug-and-play PC headset with a clear call mic and a longer warranty, choose Avantree Reverb.
• Amazon Renewed JBL Quantum TWS — biggest strength: a 2.4GHz low latency connection via the included USB-C dongle, plus JBL Dual Source so a Bluetooth call can interrupt your game and hand you back to the wireless connection afterwards.
• Amazon Renewed JBL Quantum TWS — biggest trade-off: it is a Renewed unit with a 90-day limited warranty, and one of its headline features (JBL QuantumSURROUND) only works on PC with the JBL QuantumENGINE software.
• Avantree Reverb — biggest strength: plug-and-play USB-A/USB-C dongle with no pairing step, a stated 80ms low latency figure, and a 10mm graphene driver pushing aptX Adaptive up to 24-bit/96kHz.
• Avantree Reverb — biggest trade-off: it isolates sound passively rather than cancelling it actively, and its Bluetooth path is the fallback rather than the main event.
• Pick the JBL if you want adaptive ANC, Ambient Aware and a gaming-first feature set.
• Pick the Avantree Reverb if you want the simplest possible PC setup and the longer warranty.
This is a gaming earbud first and a music earbud second. The centrepiece is the 2.4GHz low latency wireless connection to compatible devices through the USB-C dongle — and the dongle stores inside the charging case, which matters more than it sounds, because a dongle you can't lose is a dongle you'll actually take with you. The earbuds also work as ordinary Bluetooth 5.2 earbuds with phones and tablets, with a stated 10-metre range.
The second thing that stands out is JBL Dual Source. Once you're connected over 2.4GHz, an incoming call can come in over Bluetooth, and when you hang up you drop back to the lossless wireless connection. If you've ever missed a call because your gaming audio had your phone locked out, that handoff is the whole point. Add True Adaptive Noise Cancelling that self-calibrates, Ambient Aware for hearing your surroundings, and six beamforming microphones for voice pickup, and you have a fairly complete package.
Who should buy it? Someone who games on PC or a compatible device, wants the lowest-latency path the earbud offers, and values active noise cancelling for commutes and noisy rooms. The dynamic drivers cover 20Hz–20kHz, the case is rated 24 hours of battery, and controls are touch-based on the earbuds themselves.
Avantree Reverb: Who It's For
The Reverb is built around a different idea: make the PC connection brainless. Plug the C81 USB dongle into a USB-C port, or use the included USB-C to USB-A adapter for an older port, and you're running — no pairing, no menu diving. Bluetooth 5.2 is there as a second path for phones and other sources, with the same 10-metre class 2 range, but the dongle is clearly the intended route.
The audio hardware is the interesting part. A 10mm graphene dynamic driver with aptX Adaptive is rated for 24-bit/96kHz, and the frequency range runs 20Hz–48kHz — noticeably wider on the top end than the JBL's 20kHz ceiling, which is the kind of spec that shows up as detail and airiness rather than a dramatic difference. Low frequency enhancement is called out for bass, and impedance is 32 ohm.
Calls are the other focus. Four built-in microphones with cVc 8.0 noise filtering and aptX Voice are there to keep your voice clean, and the earbuds support A2DP, AVRCP, HFP and HSP profiles — the standard set that makes them behave properly as a headset for virtual meetings, not just as music earbuds. Avantree states 80ms of latency, which is a concrete number and the kind of figure that matters when you're watching for whether a footstep lands with the animation.
Battery is 7 hours in the buds and 30 hours with the case, with a 1.5-hour charge time. Noise control is sound isolation only — no active cancellation, so you're relying on the seal from the included tips.
Who should buy it? PC and laptop users who want a dongle they plug in once, people who spend their day on video calls and want the mic to actually work, and anyone who wants the comfort of a 24-month warranty (with registration covering the first 12 months of return shipping) plus chat, email, phone, video and FAQ support. Who should skip it? Anyone who needs active noise cancelling for flights or loud offices, and anyone who wants their dongle to live inside the charging case — here it's a separate piece to keep track of.
• Best for active noise cancelling → Amazon Renewed JBL Quantum TWS (True Adaptive Noise Cancelling plus Ambient Aware; the Reverb is sound isolation only).
• Best for the simplest PC setup → Avantree Reverb (plug the dongle in, no pairing step; the JBL expects you to manage a 2.4GHz path and a Bluetooth path).
• Best for calls and meetings → Avantree Reverb (4 mics, cVc 8.0 noise filtering, aptX Voice, and the standard HFP/HSP headset profiles).
• Best for gaming immersion on PC → Amazon Renewed JBL Quantum TWS (JBL QuantumSURROUND via QuantumENGINE, plus 6 beamforming mics for voice chat).
• Best for battery life → Amazon Renewed JBL Quantum TWS (24 hours with the case versus 7 hours in the buds and 30 with the case on the Reverb — close, but the JBL spreads it more evenly).
• Best for high-resolution audio specs → Avantree Reverb (aptX Adaptive at 24-bit/96kHz and a 20Hz–48kHz range, versus 20Hz–20kHz on the JBL).
• Best for warranty peace of mind → Avantree Reverb (24-month warranty versus 90 days limited on the Renewed JBL).
• Best for switching between game audio and phone calls → Amazon Renewed JBL Quantum TWS (JBL Dual Source hands you back to 2.4GHz after a Bluetooth call).
In my opinion, the JBL Quantum TWS is the better pick if gaming is genuinely the job — the 2.4GHz dongle, Dual Source call handoff and adaptive ANC are features built specifically for that, and you're accepting a short warranty in exchange. But I'd buy the Avantree Reverb for most people reading this, because the plug-and-play dongle, the stronger call hardware and the 24-month warranty make it the earbud you'll stop thinking about. If you're on PC all day and game on the side, that's the one.
FAQ
what is low latency gaming in earbuds
which low latency is best for gaming earbuds
A dedicated 2.4GHz dongle connection is generally the faster, more stable route for gaming than Bluetooth, because it skips the codec and pairing overhead. The JBL Quantum TWS is built around exactly that, while the Avantree Reverb also ships a dongle and quotes 80ms. Either way, plugging the dongle in beats relying on the Bluetooth path.
what is low latency gaming mode in earbuds
It's a mode or connection type that shortens the audio processing delay so sound tracks the picture. On the JBL Quantum TWS that's the 2.4GHz low latency wireless connection through the included USB-C dongle, which stores in the charging case. On the Reverb it's the dongle-based connection rated at 80ms.
does the renewed JBL come with the same accessories as a new one
This listing includes the headphones, the wireless dongle, the charging case, three sizes of ear tips, a charging cable, a warranty sheet and a safety sheet as one item. What differs is the coverage: it carries a 90-day limited warranty rather than a full-length one, which is worth weighing before you buy.
