• Corsair HS80's biggest strength: dual-purpose design — low-latency 2.4GHz wireless for gaming plus Bluetooth 5.2 for mobile, with up to 65 hours over 2.4GHz and up to 130 hours over Bluetooth.
• Corsair HS80's biggest trade-off: it's a full over-ear gaming headset, so it's bulkier and more involved than a set of earbuds you just slip in.
• Avantree HT4186-Q's biggest strength: a plug-and-play TV setup with a transmitter, aptX Adaptive and under 50ms latency, plus a 6dB optical volume boost.
• Avantree HT4186-Q's biggest trade-off: it only works with TVs that have Optical, AUX (3.5mm) or RCA output — not HDMI-only TVs, and it won't pass audio through to a soundbar.
• Pick Corsair HS80 if you game on PC, Mac, PS5, PS4 or mobile and want one headset for both competitive play and everyday Bluetooth listening.
• Pick Avantree HT4186-Q if you mainly want late-night TV audio that stays in sync without waking anyone, and your TV has the right output.
The HS80 is built around a simple idea: give you one headset that handles two very different jobs. On the gaming side, it uses low-latency 2.4GHz wireless with a range of up to 50 feet and 24bit/96kHz audio, which is double the resolution of many typical gaming headsets. On the everyday side, it connects over Bluetooth 5.2, so you can pair it with a phone or tablet and use it like any other wireless headset. The spec sheet lists audio latency around 20 milliseconds, which is part of why it feels responsive during play.
Battery is where it stands out. Corsair rates it at up to 65 hours over 2.4GHz and up to 130 hours over Bluetooth with RGB off (and up to 24 hours over 2.4GHz with RGB on). A 1.5-hour charge time means you're not babysitting a cable all evening. The build is aluminum and plastic with memory foam ear pads wrapped in breathable cloth, plus a floating headband, and it's over-ear, so it's designed to sit on your head for long sessions rather than disappear into a pocket.
Avantree HT4186-Q: Who It's For
The HT4186-Q is a different animal entirely — it's a TV-first audio kit. The package pairs in-ear neckband earbuds (NB16-Q) with an Audikast-3 transmitter, optical and USB-C cables, and a 3.5mm jack option. You plug the transmitter into a power outlet, connect it to your TV's Optical, AUX or RCA output, power both pieces on, and they connect automatically. If you're using optical, you switch your TV's audio settings to "Optical" and "PCM / Stereo." Avantree also notes that on Smart TVs with built-in Bluetooth, like a 2024 Samsung TV, the earbuds can connect straight to the TV, and there's an interactive setup guide you reach by scanning a QR code on the product.
The headline feature is sync. Avantree rates latency at under 50ms using aptX Adaptive, and the data sheet lists audio latency around 50 milliseconds, which is the whole point — no lip-sync lag. The Qualcomm chipset is there for clearer sound and stable connections, and there's a built-in 6dB optical volume boost, which addresses a real problem: optical connections often come through quiet and you can't adjust them at the TV.
A few honest limits. It won't work with HDMI-only TVs, and it doesn't pass audio through to a soundbar — so if your TV only has HDMI out, this isn't your product. Avantree also states it's not recommended for bass enthusiasts. The earbuds are rated at about 20 hours of battery life with a 2-hour charge (3 hours for the carrying case), and the Bluetooth range is listed at 10 meters.
Who should buy it: someone who wants private, synced TV audio — late-night viewing, a hard-of-hearing family member, or a household where the TV competes with everyone else. Who should skip it: gamers, bass lovers, and anyone whose TV lacks optical, AUX or RCA output.
Side-by-Side: Which Should You Choose?
• Best for low-latency gaming → Corsair HS80. 2.4GHz wireless with roughly 20ms latency is purpose-built for play.
• Best battery life → Corsair HS80. Up to 65 hours over 2.4GHz and up to 130 hours over Bluetooth, versus about 20 hours on the HT4186-Q.
• Best for a quiet living room → Avantree HT4186-Q. In-ear earbuds with sound isolation are made for private listening.
• Best for cross-platform gaming → Corsair HS80. PC, Mac, PS5, PS4 and mobile are all covered.
• Best for optical TVs with weak volume → Avantree HT4186-Q. The 6dB optical volume boost is a targeted fix for a common annoyance.
• Best for comfort over long sessions → Corsair HS80. Memory foam pads, cloth fabric and a floating headband are built for hours on end.
• Best simple setup for non-technical users → Avantree HT4186-Q. Plug in, power on, auto-connect — with the caveat that your TV needs the right port.
If I had to pick one, I'd buy the Corsair HS80. In my opinion it covers more ground: low-latency 2.4GHz for gaming, Bluetooth 5.2 for everything else, and battery figures that mean you rarely think about charging. The HT4186-Q is excellent at exactly one job — synced TV audio with a volume boost — and if that's your only need, it's the smarter, simpler choice. But as a single headset for gaming, media and daily Bluetooth use, the HS80 is the more versatile purchase. Check the current price on Amazon before you decide, since both sit in very different budget brackets.
how to make bluetooth headphones low latency
The most reliable route is to use a dedicated low-latency connection rather than standard Bluetooth audio. The Corsair HS80 does this with its 2.4GHz wireless receiver, rated at roughly 20ms latency, while the Avantree HT4186-Q uses its included transmitter with aptX Adaptive at under 50ms.
how to get low latency on bluetooth headphones windows 11
On Windows 11, pair the headset and then use a low-latency codec or a dedicated dongle where supported. The Corsair HS80 ships with a wireless USB receiver for its 2.4GHz mode, which sidesteps Bluetooth codec lag entirely — that's the cleanest option on a PC.
do bluetooth headphones have latency
Yes, standard Bluetooth audio always carries some delay, which is why lip-sync issues show up on TV and video. Both headsets here address it: the HS80 through 2.4GHz wireless, and the HT4186-Q through aptX Adaptive with a transmitter, rated under 50ms.
how to get low latency on bluetooth headphones
Use the lowest-latency path the hardware supports, not plain Bluetooth if you can avoid it. For the HS80 that means the 2.4GHz receiver; for the HT4186-Q it means plugging in the Audikast-3 transmitter and switching your TV to Optical with PCM/Stereo audio.
