How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wireless motorcycle helmet headset with a long-lasting battery, dual-rider intercom and hands-free calling for the office commute, choose BTQILEYOO Y10-2X; if you need a Bluetooth transmitter that sends your TV's audio to two pairs of headphones at once, choose Avantree Audikast 3.
• BTQILEYOO Y10-2X — biggest strength: a helmet-mounted Bluetooth 5.3 headset with a 1000mAh battery, up to 32 hours of music playback and a dual 300m intercom that pairs two riders.
• BTQILEYOO Y10-2X — biggest trade-off: it is a helmet speaker system, not a general-purpose audio device, so it only makes sense if you actually wear a helmet.
• Avantree Audikast 3 — biggest strength: it connects two Bluetooth headphones to one TV simultaneously, with aptX-Adaptive support and a 100ft / 30m range for private listening.
• Avantree Audikast 3 — biggest trade-off: it only works with TVs that have Optical (TOSLINK) or 3.5mm AUX outputs — HDMI-only TVs are out.
• Who each is for: the Y10-2X suits riders who want calls, music and intercom on the move; the Audikast 3 suits anyone who wants to watch TV without disturbing the room.
The Y10-2X is built around a simple idea: keep a rider connected without taking their hands off the bars. It's a Bluetooth 5.3 headset that mounts inside a helmet, with 40mm graphene dynamic drivers covering a 20Hz–20,000Hz range at 32 ohm impedance. In practice that means music, navigation prompts and phone calls all run through the same pair of helmet speakers, and the microphone uses dual noise cancellation plus a windproof sponge to fight wind roar — the single biggest enemy of helmet audio.
The features that matter most day to day are the ones you'd otherwise have to stop for. Calls can auto-answer in 10 seconds, so you never fumble for a phone mid-ride. A voice-control button summons Siri or Google Assistant for hands-free tasks. And it connects two phones to one unit at once, which is genuinely useful if you carry a work phone and a personal one — you toggle between music, navigation and calls on whichever device you need.
Who should buy it: riders who commute, tour, or ride in pairs and want intercom plus calls without stopping. Who should skip it: anyone who doesn't wear a helmet, and anyone hoping for a plug-and-play TV audio solution — that's not what this is. The dual 300m intercom also only shines if you ride with a second headset.
Avantree Audikast 3: Who It's For
The Audikast 3 solves a completely different problem: getting TV audio into headphones instead of into the room. It's a Bluetooth 5.3 transmitter that takes audio from a TV's Optical (TOSLINK) or 3.5mm AUX output and sends it wirelessly to Bluetooth headphones or speakers. Two people can pair two sets of headphones at once and watch the same show together — the classic "one person wants it loud, the other doesn't" fix.
The spec sheet reads like a purpose-built TV accessory. aptX-Adaptive support keeps audio quality high and delay low with compatible headphones, which matters for lip-sync. Range is rated up to 100ft / 30m, so you can move around the room or into the kitchen without losing the connection. There's built-in volume control right on the transmitter — genuinely helpful when your TV outputs fixed-level audio and the remote's volume buttons do nothing. Status LEDs make pairing, connection and codec states easy to read.
Two limitations are worth repeating because they're the whole buying decision. First, it does not work with HDMI-only TVs — you need an Optical or AUX port, full stop. Second, when using Optical, the TV's audio setting must be switched to PCM. Neither is hard, but both catch people out. This is a corded device, so it lives near the TV rather than in your pocket.
Who should buy it: anyone with Optical or AUX audio out who wants private TV listening, especially couples or households with mixed hearing needs. Who should skip it: HDMI-only TV owners, and anyone expecting a portable or helmet-based solution.
Side-by-Side: Which Should You Choose?
• Best for TV audio → Avantree Audikast 3. It's designed to move TV sound to headphones, nothing else.
• Best battery life → BTQILEYOO Y10-2X. Up to 32 hours of playback and 18 months standby versus a corded transmitter.
• Best for two-headphone sharing → Avantree Audikast 3. Two Bluetooth headphones paired to one transmitter simultaneously.
• Best for hands-free calls → BTQILEYOO Y10-2X. Auto-answer, voice control and dual noise cancellation.
• Best for weather resistance → BTQILEYOO Y10-2X. IPX6 waterproofing down to -20°F.
• Best for long-range freedom → Avantree Audikast 3. Up to 100ft / 30m, versus 10m Bluetooth range on the headset.
• Best if your TV only has HDMI → neither. The Audikast 3 needs Optical or AUX, and the Y10-2X isn't a TV transmitter.
For most people reading this, the honest answer is that these two products don't compete — they solve different problems, so the right pick depends on what you're actually trying to fix. If I were shopping for a helmet headset for the office commute, riding with music, navigation and calls, I'd buy the BTQILEYOO Y10-2X: the 32-hour battery, dual 300m intercom and IPX6 build are the features that would actually get used every day. If I needed to watch TV without waking the house, I'd buy the Avantree Audikast 3 without hesitation — as long as my TV has Optical or AUX. In my opinion, the Y10-2X is the stronger all-rounder for anyone who rides.
They do different jobs, so "worth it" depends on your need. The Y10-2X is a helmet headset for music, calls and intercom; the Audikast 3 is a TV transmitter for headphones. Neither replaces the other.
No. It needs a TV with an Optical (TOSLINK) or 3.5mm AUX audio output. HDMI-only and HDMI ARC/eARC-only TVs aren't supported, and Optical audio must be set to PCM.
Yes — it connects two mobile phones to one unit, so you can switch between listening to music, navigation and answering calls on either device. Bluetooth range is around 10 meters.
