If you want the longest battery life and a boom-mic headset built for marathon gaming sessions on PS5, Switch or PC, choose Avantree C519M; if you need compact in-ear buds with active noise cancelling and a 2.4GHz dongle for VR headsets like Meta Quest, choose KASOTT 2.4GHZ.
• Avantree C519M biggest strength: A pre-paired over-ear headset plus USB-C adapter that drops Bluetooth lag to under 40ms, with 16-bit stereo chat so voice and game audio never degrade each other.
• Avantree C519M biggest trade-off: It's over-ear and bulky, has no active noise cancelling, and it won't work with TVs, Xbox One or PS3.
• KASOTT 2.4GHZ biggest strength: Dual-mode 2.4GHz + Bluetooth 5.4 earbuds with ANC and a claimed 30ms latency, tiny enough to toss in a pocket.
• KASOTT 2.4GHZ biggest trade-off: In-ear buds mean shorter single-charge life (8 hours per bud), and the noise cancelling is only as good as the seal you get.
• Pick Avantree C519M if you want one headset for long PC or console sessions and you hate pairing menus.
• Pick KASOTT 2.4GHZ if you bounce between a Quest, Steam Deck, Switch and your phone and want noise cancelling on the go.
The C519M is a set, not just a headphone. You get an over-ear headset and an Avantree C51 USB-C transmitter that arrive already paired. Plug the dongle into a USB-C port on a PS5, Switch, Mac, PC, Chromebook or Linux machine, switch the headphones on, and you're playing. That's the whole setup. For anyone who has ever lost twenty minutes in a Bluetooth menu before a match, this is the appeal — no drivers, no pairing dance.
The headline number here is latency. Avantree rates the built-in low-latency link at under 40ms, versus roughly 220ms for standard Bluetooth audio. That gap is the difference between a gunshot that lands with the on-screen muzzle flash and one that trails behind it. The second number that matters is 16-bit stereo audio during chat. Avantree specifically calls out that this headset avoids the quality drop many Bluetooth adapters suffer when the microphone activates, so you can run Discord and game audio at the same time without your teammates sounding like they're on a phone call from 2004.
Who should buy it: console and PC gamers who want a mic, long sessions, and zero fuss. Who should skip it: anyone who needs TV audio (explicitly unsupported), Xbox One or PS3 owners, and people who need active noise cancelling — there is none here, only the passive isolation of the ear cups. Also note the built-in mic and control buttons won't function in wired mode.
KASOTT 2.4GHZ: Who It's For
The KASOTT GameMaster YX37 is the opposite philosophy: small, dual-mode, and built to move between devices. It carries both a 2.4GHz wireless link and Bluetooth 5.4, so you can use the included USB-C dongle for the lowest-latency path or plain Bluetooth for your phone. KASOTT rates the 2.4GHz latency at 30ms — a hair under the Avantree figure — and the plug-and-play dongle means platform switching is instant rather than a re-pairing ordeal.
The feature Avantree simply doesn't have is ANC. KASOTT uses a 13mm composite dynamic driver and active noise cancelling that adapts to your ear canal, which is genuinely useful on a train, in a dorm, or anywhere a fan or air conditioner is competing with your audio. In-ear buds with rounded silicone tips also seal naturally, and KASOTT ships multiple ear tip sizes plus an ergonomic shape designed to stay put during movement.
Battery tells a different story. Each bud runs about 8 hours, and the charging case takes that to roughly 40 hours total. There's a digital LED display on the case showing the remaining charge, and KASOTT claims 10 minutes of fast charging yields about 4 hours of playback. The dongle also passes power through so you can charge your gaming device while playing.
Who should buy it: Meta Quest 3/2, Steam Deck, PS4/PS5, Switch and PC players who want one tiny kit for everything, plus anyone who values noise cancelling and portability. Who should skip it: players who want a boom mic on a full-size headset, and anyone who dislikes in-ear fit — ANC performance depends heavily on getting a good seal. KASOTT also notes the dongle's passthrough charging wants a charger supporting USB power delivery at 9V/2A minimum.
• Best for battery life → Avantree C519M. Up to 40 hours on a single charge versus 8 hours per KASOTT bud.
• Best for lowest latency → KASOTT 2.4GHZ. Its 30ms rating edges the C519M's sub-40ms, though both are far below standard Bluetooth.
• Best for noise cancelling → KASOTT 2.4GHZ. Active noise cancellation is a feature the C519M does not offer at all.
• Best for VR and handhelds → KASOTT 2.4GHZ. It's explicitly built around Meta Quest 3/2, Steam Deck and Switch.
• Best for console + Discord at the same time → Avantree C519M. The 16-bit stereo chat guarantee is designed for exactly that.
• Best for comfort over long sessions → Avantree C519M. Over-ear cups at roughly 180g avoid in-ear pressure entirely.
• Best for travel and portability → KASOTT 2.4GHZ. Earbuds in a charging case versus a full over-ear headset.
• Best for TV audio → neither. Avantree states the C519M is not compatible with TVs, and the KASOTT kit is aimed at gaming devices.
In my opinion, the C519M is the better buy for anyone whose gaming happens at a desk or in front of a console. Forty hours of battery, a boom mic, stereo chat that doesn't collapse when you talk, and a pre-paired dongle solve the three things that annoy me most about Bluetooth gaming. The KASOTT buds win on portability and ANC, and I'd genuinely recommend them if you game on a Quest or Steam Deck and want noise cancelling in a pocket-sized kit. But for the classic "headphones plus dongle, low latency, all weekend" job, I'd take the Avantree set. Check the current price on Amazon before you commit — that's the one variable I can't compare for you here.
how to make bluetooth headphones low latency
The most reliable route is a dedicated low-latency link rather than standard Bluetooth audio. Both products here do it with a bundled USB-C dongle: Avantree rates its link under 40ms, KASOTT rates 2.4GHz at 30ms, versus roughly 220ms for ordinary Bluetooth.
do bluetooth headphones have latency
Yes — standard Bluetooth audio typically adds around 220ms of lag, which is enough to see on screen. Headsets and earbuds built around a low-latency adapter or 2.4GHz connection, like these two, cut that to 30–40ms, which is effectively imperceptible for gaming and video.
how to get low latency on bluetooth headphones windows 11
On Windows 11, plug the USB-C dongle into your PC and let the pre-paired set connect — the C519M works with Windows, Mac, Chromebook and Linux this way, and KASOTT's dongle is plug-and-play too. That bypasses the operating system's standard Bluetooth audio path, which is where most of the delay comes from.
how to get low latency on bluetooth headphones
Pick hardware designed for it. Avantree builds the low-latency link directly between its Type-C adapter and the headphone and auto-switches between music and talk modes; KASOTT pairs a 2.4GHz dongle with Bluetooth 5.4 so you can choose the fast path when latency matters and plain Bluetooth when it doesn't.
