How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a featherweight pair of Bluetooth earbuds built around a genuinely low 45 ms game mode and a long-lived charging case, choose TOZO Earbuds; if you need to plug a 2.4GHz dongle into a console or VR headset and want active noise cancelling on top, choose KASOTT 2.4GHZ.
• TOZO Earbuds — biggest strength: A dedicated game/music mode with a claimed 45 ms latency, Bluetooth 5.3, and a 30-hour charging case, all in a compact in-ear design with a breathing light for gaming atmosphere.
• TOZO Earbuds — biggest trade-off: No active noise cancelling ("noise control: None"), touch controls only, and it is Bluetooth-only — there is no dongle, so it can't do true 2.4GHz for consoles.
• KASOTT 2.4GHZ — biggest strength: Dual-mode 2.4GHz + Bluetooth 5.4 with a USB-C dongle, 30 ms latency, ANC, a 13 mm dynamic driver, and a 40-hour total battery with a 10-minute fast charge giving 4 hours.
• KASOTT 2.4GHZ — biggest trade-off: It asks more of you — the dongle needs a charger that supports USB power transfer at a minimum 9V/2A output for the pass-through charging trick, and the VR compatibility excludes VR devices themselves from what ships in the box.
• Who each is for: TOZO for phone-first mobile gamers and everyday listeners who want a cheap, light, low-latency Bluetooth set; KASOTT for PC, PS5/4, Switch, Steam Deck and Meta Quest players who want plug-and-play 2.4GHz and noise cancelling.
The TOZO G1S is a phone-first gaming earbud. Everything in its spec sheet points one direction: Bluetooth 5.3 with HSP, HFP, A2DP and AVRCP support, a 16-metre wireless range, and a stated 45 ms latency that the brand frames as more than three times faster than standard Bluetooth headphones. There's a physical-feeling logic to it — a game mode tuned to catch footsteps, gunfire and cars, and a breathing light on the bud that exists purely to pull you into the scene. For a mobile player who wants that split-second audio sync without buying a dongle, that's the whole pitch.
On the audio side it's a 32-ohm dynamic driver covering 20 Hz to 20,000 Hz, tuned for punchy bass, a mellow midrange and clear treble. Touch controls handle media, and the buds pair automatically with each other out of the case — pull both out, pick "TOZO-G1S" in your phone's Bluetooth list, done. Battery is the quiet win here: over 6 hours per charge in game mode, up to 30 hours with the case, and a full case charge in under 2 hours via USB-C. The case indicator goes red slow-flash while charging and green slow-flash when full.
Who should buy it: mobile gamers on Android or iOS, commuters, and anyone who wants a light in-ear set with a proper low-latency mode and a case that lasts a week of short sessions. Who should skip it: anyone who needs active noise cancelling, anyone gaming mainly on a console or PC where Bluetooth latency is the bottleneck, and anyone who dislikes touch-only controls. The single-earbud weight and rounded silicone tips are built for stability during exercise or long sessions, but there's no ANC to block a noisy room.
The KASOTT GameMaster YX37 is the more ambitious product, and it's aimed at a different buyer entirely. Its headline trick is dual-mode connectivity: a 2.4GHz USB-C dongle for plug-and-play, plus Bluetooth 5.4 for everything else. That means you can jump between a PS5, a Switch, a Steam Deck, a PC or a Meta Quest without re-pairing — the dongle does the work. Latency is stated at 30 ms, which is the lowest figure between these two, and 2.4GHz is inherently more stable than Bluetooth for competitive play.
Then there's ANC. KASOTT pairs a 13 mm composite dynamic driver with active noise cancelling that adapts to your ear canal shape, boosting bass, mids and highs while cutting ambient noise. That's a real difference from the TOZO, which has no noise control at all. The brand also pitches clear communication during calls and team chat, so it's as much a headset for talking as for listening. Battery is 8 hours per bud and up to 40 hours with the case, and the charging case has a digital LED display so you can see the level instead of guessing from a blinking light.
The clever bit — and the catch — is the dongle's pass-through charging. You can charge your gaming device through the USB-C plug while you play, but only with a charger that supports USB power transfer at a minimum 9V/2A output. The box includes the dongle, replacement earplugs and a manual, and it's rated for teens and up with a 1-year manufacturer warranty. Fit is handled by multiple earbud sizes and a lightweight ergonomic shell.
Who should buy it: console, PC, handheld and VR players who want one set that works everywhere with the lowest latency, plus anyone who wants ANC and a battery display. Who should skip it: someone who just wants a simple pair for their phone and never touches a dongle, and anyone who wants the smallest possible carry case — the dongle is one more thing to keep track of.
Side-by-Side: Which Should You Choose?
• Best for lowest latency → KASOTT 2.4GHZ. 30 ms over 2.4GHz beats the TOZO's 45 ms Bluetooth figure, and the dongle connection is more stable under load.
• Best for console, PC, handheld or VR gaming → KASOTT 2.4GHZ. The USB-C dongle covers PS5/4, Switch, Steam Deck, PC and Meta Quest 3/2 without re-pairing.
• Best for a phone-only setup → TOZO Earbuds. Bluetooth 5.3, instant pairing out of the case, and no dongle to lose.
• Best for blocking noise → KASOTT 2.4GHZ. Active noise cancelling versus none on the TOZO.
• Best for a quick, low-fuss charge routine → TOZO Earbuds. Under 2 hours to a full case via USB-C, with simple red/green charging indicators.
• Best for sheer portability and light weight → TOZO Earbuds. A compact in-ear set with a small case and nothing extra in your pocket.
• Best for battery transparency → KASOTT 2.4GHZ. The digital LED display on the case shows the level directly.
If I were buying for myself and I play across consoles, a PC or a VR headset, I'd take the KASOTT 2.4GHZ. In my opinion the 2.4GHz dongle, the 30 ms latency, the ANC, the 13 mm driver and the 40-hour case simply do more, and the LED battery display is the kind of detail that matters daily. The TOZO G1S is the better call only if your gaming lives entirely on your phone and you want the lowest-friction, most portable option with a solid 30-hour case and a 45 ms game mode. Neither needs a price justification from me — check the current price on Amazon before you commit, since that's the one variable I can't weigh here.
do bluetooth headphones have latency
Yes — every Bluetooth connection introduces some delay, because audio has to be encoded, transmitted and decoded. Standard Bluetooth sets often sit well above 100 ms, which is why low-latency modes exist. The TOZO G1S states 45 ms in its game mode, and the KASOTT YX37 states 30 ms over 2.4GHz, so both are aimed at shrinking that gap.
how to get low latency on bluetooth headphones
The most reliable route is to use the manufacturer's dedicated low-latency or game mode, which is exactly what the TOZO G1S offers alongside Bluetooth 5.3. Pair the buds, then switch to game mode to trigger the 45 ms path. Keep the buds within the stated 16-metre range and avoid heavy interference for the cleanest result.
how to make bluetooth headphones low latency
Two practical levers: turn on the low-latency/game mode in the app or via the touch controls, and reduce distance and obstructions between the buds and your device. If your hardware supports a dongle instead, that's the bigger jump — the KASOTT YX37 drops to a stated 30 ms by using its 2.4GHz USB-C connection rather than Bluetooth.
how to get low latency on bluetooth headphones windows 11
On a Windows 11 PC, the cleanest path is a dedicated 2.4GHz dongle rather than Bluetooth, which is precisely what the KASOTT 2.4GHZ includes for PC use — plug the USB-C dongle in and it's plug-and-play. If you're using Bluetooth instead, enable the headset's game mode and keep the PC's Bluetooth adapter close and unobstructed.
