How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a comfortable all-day on-ear headset with a detachable boom mic, a dedicated charging stand, and high-definition aptX audio for both music and calls, choose Avantree Alto Clair; if you need a work headset that ships with its own USB dongle for plug-and-play PC and softphone use, choose Gixxted Headset.
• Avantree Alto Clair biggest strength: aptX HD and aptX Low Latency support plus a detachable boom mic with a mute button — a rare combination that covers music, movies and calls in one headset, with a charging base to keep it topped up.
• Avantree Alto Clair biggest trade-off: No USB adapter in the box, and the mic and controls don't work in wired mode — so PC users with Bluetooth issues need to add a dongle separately.
• Gixxted Headset biggest strength: A bundled USB dongle and Bluetooth 5.4 make it the more direct plug-in-and-go option for computers, and the mic is tuned for voice with active noise cancellation.
• Gixxted Headset biggest trade-off: The stated frequency range (85 Hz – 255 Hz) points to a voice-first tuning, not a music-first one, and there's no wired jack as a fallback.
• Who each pick is for: Avantree Alto Clair for people who want one headset for calls and entertainment; Gixxted Headset for people whose day is mostly meetings on a computer.
The Alto Clair is a Bluetooth 5.0 on-ear headset built around flexibility. It pairs with basically anything Bluetooth — phone, laptop, tablet, transmitter — and it carries aptX HD for a "better-than-CD" listening experience, so music and shows don't sound thin. It also supports aptX Low Latency, which cuts Bluetooth delay down to roughly 32–40 ms, a range the human ear can't detect. That matters if you watch video or game, because lip-sync drift is the thing that ruins wireless audio for most people. Note the caveat from the spec sheet: with non-aptX-LL devices, you may get around 200 ms of delay, which is fine for calls but not ideal for TV and movies.
Who should buy it: Anyone who wants one wireless headset for both work calls and entertainment, especially if their source devices support aptX. Who should skip it: If your PC has flaky Bluetooth or you want a single-box solution for computer audio, look elsewhere — the Alto Clair doesn't include a USB adapter, and the boom mic and buttons go dead in wired mode, so the 3.5 mm cable is a listening-only fallback. Heavy bass fans should also look elsewhere; the tuning is deliberately balanced toward clarity.
Gixxted Headset: Who It's For
The Gixxted KH109 is positioned squarely as a work headset. It runs Bluetooth 5.4 — the newer of the two standards here — and it comes with a USB dongle in the box, which is the single most practical difference between these two products. If you've ever fought with a desktop PC that refuses to hold a stable Bluetooth connection, the dongle sidesteps that fight entirely: you plug it in, select it as both your output and input device, and you're on a call. The user guidance in the spec sheet even covers the classic troubleshooting cases — unplug the dongle and try another USB port, reset the connection records by holding the MFB and volume-up buttons, mute other system sounds to clean up call audio. That's a headset designed by people who expect you to be on Teams or a softphone all day.
The microphone gets active noise cancellation, and the frequency range is listed at 85 Hz – 255 Hz. Read that number carefully: it's a narrow band centered on the human voice, which is exactly what you want for speech intelligibility and exactly what you don't want if you plan to listen to music. It's also worth being clear that the "noise control: Active Noise Cancellation" field in the spec sheet refers to the design's noise-control feature; I'd treat the voice-focused tuning as the real signal here rather than assuming it silences a noisy office the way over-ear ANC headphones do.
Build-wise it's an on-ear design in black with fabric and silicone materials — plastics and soft goods rather than leather-like padding — and there's no headphone jack at all, so wireless is your only route. Charging takes about two hours. It carries a 1-year warranty, against Avantree's 24 months.
Who should buy it: Remote workers, call-center and office users who live in softphone apps and want a dongle that just works with a computer. Who should skip it: Music listeners, movie watchers, and anyone who wants a wired fallback or a longer warranty.
• Best for PC and softphone calls → Gixxted Headset. The bundled USB dongle and Bluetooth 5.4 make computer pairing far less fussy.
• Best for music, movies and games → Avantree Alto Clair. aptX HD and aptX Low Latency are the reason; the Gixxted's 85–255 Hz range is voice-first.
• Best for mic flexibility → Avantree Alto Clair. A detachable boom mic with a dedicated mute button, plus a separate assistant button.
• Best for voice clarity on a noisy line → Gixxted Headset. Its noise-cancelling mic design and voice-tuned range are aimed straight at intelligible speech.
• Best for keeping the headset charged and tidy → Avantree Alto Clair. The included charging base doubles as a desktop stand.
• Best for all-day comfort on a light head → Avantree Alto Clair. 155 g, protein-style earpads and an adjustable headband.
• Best warranty coverage → Avantree Alto Clair. 24 months versus 1 year.
• Best for someone who wants a wired option → Avantree Alto Clair. It has a 3.5 mm port (with the caveat that the mic and controls don't work in wired mode); the Gixxted has no jack at all.
In my opinion, Avantree Alto Clair is the better buy for most people, because it does more jobs well: aptX HD for music, aptX Low Latency for video, a detachable boom mic with quick mute for calls, a charging stand, and a two-year warranty. The one thing it can't do is guarantee smooth PC audio out of the box — that's the Gixxted's whole reason to exist, and if your workday is a wall of Teams calls on a stubborn desktop, I'd take the Gixxted instead. But if you want one headset that handles the meeting at 10 a.m. and the movie at 10 p.m., I'd choose the Alto Clair.
Yes, with a caveat. It works with any Bluetooth-enabled computer, but if your PC's built-in Bluetooth is unreliable or you want lag-free audio, Avantree recommends pairing it with one of their USB Bluetooth adapters — the adapter isn't included.
Yes. It's a standard Bluetooth 5.4 headset, so you can pair it directly with a phone or laptop. The dongle is there for computers where Bluetooth pairing is unreliable or where you want the headset recognized cleanly as both input and output.
Avantree Alto Clair, in my opinion. aptX HD and a 20 Hz – 20,000 Hz range are built for full-range audio. The Gixxted's 85 Hz – 255 Hz range is centered on speech, which is great for calls and poor for music.
Yes — I deliberately don't quote prices here, since they move around. Use the price button on this page to check the current cost of each on Amazon, then weigh that against what you actually need: dongle-based PC calling, or a do-everything headset.
