How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a self-contained low-latency gaming audio solution, choose KASOTT 2.4GHZ; if you need to turn an existing wired 3.5mm device into something Bluetooth-capable, choose Wodgreat Audio Adapter. These two products get lumped together in search results, but they solve completely different problems. One is a pair of earbuds with its own dongle and its own radio link. The other is a tiny bridge that adds Bluetooth to hardware that never had it. If low-latency Bluetooth is what you're chasing, the KASOTT pair is the one built for it out of the box, while the Wodgreat adapter is the fix for the airplane seat, the gym machine and the older TV.
• KASOTT 2.4GHZ — biggest strength: a 30ms low-latency 2.4GHz link via its own USB-C dongle, plus Bluetooth 5.4, ANC and up to 40 hours of total playback with the case.
• KASOTT 2.4GHZ — biggest trade-off: it's earbuds, not an adapter, so it only helps you if you actually want to wear in-ear buds, and the 2.4GHz mode needs a USB-C port or dongle host nearby.
• Wodgreat Audio Adapter — biggest strength: TX/RX flexibility with 3.5mm aux jacks, an LCD status screen, an integrated mic and roughly 15–16 hours of runtime.
• Wodgreat Audio Adapter — biggest trade-off: it doesn't make your headphones low-latency by magic — it adds Bluetooth to wired gear, and its latency is bounded by Bluetooth 5.3 itself.
• Who each pick is for: KASOTT for gamers and VR users who want the fastest possible wireless path; Wodgreat for travelers, drivers and anyone with a wired device that needs a wireless upgrade.
The KASOTT GameMaster Buds YX37 (model KST-GameMaster-YX37) are built around one idea: cut the delay. Instead of relying on Bluetooth alone, they ship with a USB-C dongle that carries a 2.4GHz signal rated at 30ms latency. That's the number that matters here. Bluetooth audio has an inherent buffering delay, and 2.4GHz dongle audio sidesteps most of it by using a dedicated radio link — the same trick wireless gaming headsets have used for years. On top of that you get Bluetooth 5.4 as a second mode, so you can jump between a console and a phone without repairing. The pitch is dual-mode connectivity: plug the dongle into a PC, PS4, PS5, Switch or a Meta Quest headset, and you're in low-latency mode; go Bluetooth when you're out and about.
The rest of the package is aimed at long sessions. There's active noise cancellation with a 13mm dynamic driver covering 20Hz–20,000Hz, which helps both in-game comms and calls. Battery is quoted at 8 hours per charge and up to 40 hours with the case, with a fast-charge claim of 10 minutes for 4 hours of play. The case has a digital LED readout so you can see the level without guessing. There's also a USB-C pass-through so you can charge a VR headset or handheld while you play. Fit-wise, they're in-ear with rounded tips and multiple earbud sizes, plastic housing, white finish, touch and push-button controls.
Buy KASOTT 2.4GHZ if you game or use VR and want the shortest possible path between what happens on screen and what you hear — especially if you're on a Quest, Steam Deck, Switch or PlayStation. Skip it if you don't want in-ear buds at all, or if your main problem is a wired TV, a car stereo or a gym machine with a 3.5mm jack. Those aren't earbud problems; they're adapter problems.
The Wodgreat Audio Adapter is a different animal entirely. It's a small transmitter/receiver that plugs into anything with a 3.5mm aux jack and either sends audio out (TX) or receives it (RX). Bluetooth 5.3 gives it a rated 10-meter range, fast pairing and stable reconnection to the last device it talked to. There's an LCD screen showing battery level and pairing status, which sounds minor until you've fumbled with a blinking LED on a plane tray table. It has an integrated microphone for hands-free calls through a car's speakers, and it runs about 15–16 hours per charge with USB-C fast charging that fills it in roughly two hours.
Where it shines is the long tail of hardware that never got Bluetooth. In-flight entertainment systems with a headphone jack. A TV that doesn't expose Bluetooth. Gym equipment with an audio out. An older car stereo. A wired speaker or projector. The TX/RX switch is the key feature — flip it one way and you're feeding audio into your Bluetooth headphones, flip it the other and you're turning a wired speaker into a Bluetooth target. The package includes a 3.5mm audio cable, a USB-C power cable and a manual, and Wodgreat backs it with a warranty and support channel.
Buy Wodgreat Audio Adapter if you own wired gear you want to keep using wirelessly, or you travel and want your own headphones on the plane. Skip it if you expect it to eliminate the latency of your Bluetooth headphones — it can't. It adds Bluetooth; it doesn't replace it with something faster.
• Best for true low-latency gaming → KASOTT 2.4GHZ. The 30ms 2.4GHz dongle mode is the entire point of the product.
• Best for making an old TV, car or gym machine wireless → Wodgreat Audio Adapter. 3.5mm in, Bluetooth out.
• Best for VR and handhelds → KASOTT 2.4GHZ. It explicitly lists Meta Quest 3/2, Steam Deck and Switch compatibility, and even offers USB-C charging pass-through.
• Best for travel and flights → Wodgreat Audio Adapter. Compact, LCD screen, 15–16 hours, and it pairs with your own headphones.
• Best battery story → it depends on how you count. KASOTT gives 8 hours per charge and up to 40 hours with the case; Wodgreat gives a longer single-charge window at roughly 15–16 hours.
• Best for taking calls → either, differently. KASOTT uses its ANC and dual-link setup for in-game and call audio; Wodgreat uses its built-in mic to push calls through car speakers.
• Best if you already own good wired headphones → Wodgreat Audio Adapter. You keep the headphones you like and just cut the cable.
• Best if you want one box with everything → KASOTT 2.4GHZ. Buds, dongle, case and ANC, no extra parts required.
If low latency is the actual goal, I'd buy the KASOTT 2.4GHZ. In my opinion, the 2.4GHz dongle is the only thing in this comparison that directly attacks the delay problem, and the Bluetooth 5.4 fallback plus ANC and 40-hour total battery make it a genuinely complete kit. The Wodgreat Audio Adapter is excellent at what it does — I'd recommend it without hesitation to anyone with a wired TV, car or plane seat — but it's a bridge, not a latency fix. Buy the Wodgreat only if your problem is "my device has no Bluetooth," not "my Bluetooth is too slow."
FAQ
how to make bluetooth headphones low latency
how to get low latency on bluetooth headphones windows 11
On Windows, use a dongle-based connection rather than the built-in Bluetooth radio. The KASOTT 2.4GHZ ships with a USB-C dongle designed for exactly this, and it lists PC compatibility. Its Bluetooth 5.4 mode is a fallback for when you're away from the dongle.
how to get low latency on bluetooth headphones
You have two levers: the codec/link and the source. A dedicated 2.4GHz transmitter is the biggest single improvement, which is why the KASOTT kit includes one. A 3.5mm transmitter like the Wodgreat Audio Adapter improves convenience and sync for movies, but it still passes audio over Bluetooth 5.3, so it can't beat a 2.4GHz link.
do bluetooth headphones have latency
Yes. Bluetooth audio is buffered, so a delay exists between the source and your ears — that's inherent to the standard, not a defect in one product. It's usually tolerable for music and noticeable in games or lip-sync-heavy video. The Wodgreat adapter's low-latency claim helps with sync, while the KASOTT 2.4GHZ avoids the issue by using a separate 2.4GHz radio.
