If you want a purpose-built transmitter that turns a Nintendo Switch into a dual-headphone, voice-chat-ready audio rig, choose HomeSpot Audio Adapter; if you need to liberate in-flight entertainment from a 3.5mm jack and pipe it to your own AirPods, choose Avantree Voyager Airplane. They both convert wired audio into Bluetooth, but they solve completely different problems for completely different people.
• HomeSpot Audio Adapter — biggest strength: Built-in digital mic plus in-game voice chat, and it's the one here that can stream to two headphones at once in aptX Low Latency.
• HomeSpot Audio Adapter — biggest trade-off: It's tailor-made for the Nintendo Switch family via USB-C, so it's a poor fit for anything without that port, and it won't work with a protective case installed.
• Avantree Voyager Airplane — biggest strength: Bluetooth 5.4 with aptX Adaptive, Auracast support, and an OLED display that shows your device, battery level and audio status instead of leaving you guessing.
• Avantree Voyager Airplane — biggest trade-off: Classic Bluetooth mode handles only one headset at a time, and it's explicitly not for hearing aids, phones, tablets or TVs without a 3.5mm AUX output.
• Who each pick is for: HomeSpot for Switch players who want wireless audio and party chat; Avantree for travelers who want their own headphones on a plane.
The HomeSpot Audio Adapter is a Bluetooth transmitter built specifically for the Nintendo Switch family — both the regular Switch and the Switch Lite. It plugs into the USB-C port and transmits digital audio directly, with a Qualcomm chipset driving aptX or aptX Low Latency for low-latency transmission. Latency is listed at under 70ms over HFP or aptX LL. If your headphones don't support aptX, it falls back to standard SBC, which is worth knowing before you buy.
What genuinely sets it apart is voice chat. It has a built-in digital mic, and the brand positions it as the only Bluetooth adapter for the Switch family with one. That means hassle-free in-game voice chat in titles like Fortnite, Smite, Paladins and Friday the 13th. You can also use the built-in mic in standalone mode without pairing any Bluetooth headphones at all. Headphones with their own mic are supported over HFP too, so Discord, Nintendo Online, WhatsApp and FaceTime all become viable on the console.
Then there's dual streaming. HomeSpot claims it's the only transmitter for the Switch family that can stream to two headphones simultaneously in aptX Low Latency. For couch co-op with a friend, or for a parent and kid sharing one screen quietly, that's a real, practical feature — not a spec-sheet flourish.
Avantree Voyager Airplane: Who It's For
The Avantree Voyager Airplane is a travel-first transmitter. You connect it to an airplane entertainment system, gym equipment, or any other 3.5mm AUX source, and it sends that audio wirelessly to your AirPods, Bose headphones, or any Bluetooth headphones. It supports both standard 3.5mm AUX and dual-prong jacks, so it's designed to work with the seat-back systems you actually encounter on flights.
The standout design choice is the OLED display. Instead of blind pairing and hoping, you see the connected device, battery level, and audio status right on the screen. Anyone who has fumbled with a tiny blinking LED mid-flight will understand why that matters. Under the hood it runs Bluetooth 5.4 with a Qualcomm chipset and aptX Adaptive, and it's Auracast-ready for next-generation audio sharing with compatible earbuds and headphones such as Galaxy Buds2 Pro or WF-1000XM5. It also takes firmware updates, so it isn't frozen at launch.
Two limitations are stated plainly and you should take them seriously. In classic Bluetooth mode it supports only one headset — no dual connection. Group listening requires Auracast mode and Auracast-compatible gear. And it's not compatible with hearing aids, phones, tablets, musical instruments, or TVs without a 3.5mm AUX output; if you use Auracast-enabled hearing aids, the brand points you to a different model, the Voyager HA.
Buy it if you fly often, want your own headphones on any seat-back screen, and value seeing your connection status at a glance. Skip it if you need two classic Bluetooth headphones at once, or you're shopping for a TV or phone transmitter.
Side-by-Side: Which Should You Choose?
• Best for Nintendo Switch gaming → HomeSpot Audio Adapter. It's designed for the Switch family specifically, with USB-C digital audio.
• Best for two listeners at once → HomeSpot Audio Adapter. Dual streaming in aptX Low Latency, versus the Voyager's single classic Bluetooth connection.
• Best for flights and travel → Avantree Voyager Airplane. 3.5mm AUX and dual-prong support are built for airplane systems.
• Best for pairing confidence → Avantree Voyager Airplane. The OLED display shows device, battery and audio status.
• Best for future-proof audio sharing → Avantree Voyager Airplane. Auracast support and firmware upgradability.
• Best for the latest Bluetooth → Avantree Voyager Airplane. Bluetooth 5.4 with aptX Adaptive, versus the HomeSpot's aptX/aptX LL.
• Best for low latency on paper → HomeSpot Audio Adapter. Under 70ms over HFP or aptX LL, a figure Avantree doesn't state for the Voyager.
In my opinion, the right pick comes down to one question: what are you plugging into? If it's a Nintendo Switch, I'd buy the HomeSpot Audio Adapter — the built-in mic, in-game voice chat and dual-headphone streaming are things the Voyager can't do, and they're the whole reason to own a Switch transmitter. If you're a traveler who wants your own headphones on a plane, I'd buy the Avantree Voyager Airplane instead. Its OLED display, Bluetooth 5.4, aptX Adaptive and Auracast support make it the more capable travel tool, even though it limits you to one classic Bluetooth headset at a time. Neither is universally "better" — they're aimed at different rooms of your life.
FAQ

The Avantree Voyager Airplane is designed around Bluetooth headphones including AirPods. The HomeSpot Audio Adapter can pair with Bluetooth headphones generally, but its headline features — the built-in mic, in-game chat and aptX Low Latency — are aimed at the Switch ecosystem.
Pricing changes, so check the current price on Amazon before deciding.
