How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single wireless earpiece for calls, driving and work, choose Callez Headset; if you need to send TV audio wirelessly to hearing aids, earbuds or a room full of listeners, choose 1Mii NightPair TX Auracast. These two share only one thing in common — the letters aptX appear on both spec sheets — and that overlap is exactly where buyers get confused. One is a headset you wear. The other is a transmitter that sits next to your TV. I'll break down which one actually fits your situation.
• Callez Headset — biggest strength: a complete, self-contained calling device. Bluetooth 5.0, CVC8.0 dual-mic noise cancelling, Qualcomm aptX HD, 8 hours of talk time, 16 hours of music playback, 1.5-hour charge, 33 ft range, and dual-device pairing.
• Callez Headset — biggest trade-off: it's a mono in-ear earpiece built for voice, not a stereo listening device, and its aptX HD only pays off if your phone or laptop actually supports aptX HD.
• 1Mii NightPair TX Auracast — biggest strength: Bluetooth 6.2 with Auracast broadcast plus LC3, aptX, aptX HD, aptX Adaptive and aptX Low Latency support, HDMI ARC / Optical / 3.5 mm AUX inputs, and up to 100 ft open-air range.
• 1Mii NightPair TX Auracast — biggest trade-off: it makes no sound at all. It's a corded transmitter with no battery, so it's useless without a TV or audio source and a compatible receiving device.
• Buy the Callez if you're a trucker, driver, office worker or anyone who lives on phone calls.
• Buy the 1Mii NightPair TX if you want private or shared TV audio for hearing aids, earbuds or a group of listeners.
The Callez Headset is a Bluetooth earpiece in the classic sense: a lightweight in-ear bud with an adjustable ear hook and a boom mic you can rotate to whatever angle suits your face. It fits either ear, ships with S/M/L ear tips plus ear foam covers, and weighs in at just 16.74 g — light enough that you stop noticing it after a while. That's the whole design philosophy here: stay on your head for a full workday and stay out of the way.
Battery is the quiet headline: 8 hours of continuous talking, 16 hours of music playback, 8 days of standby, all from a 1.5-hour charge over USB-C. For a trucker running a shift, a rep on back-to-back calls, or someone who takes meetings while pacing the office, that's a realistic day of use. In my opinion, this is the pick for anyone whose priority is one earpiece that handles calls all day without fuss.
Who should skip it? If you want stereo music, immersive movie sound, or anything resembling a TV audio solution, this isn't that product. It's a voice-first tool. And if your phone doesn't support aptX HD, you'll still get good call audio — just not the aptX HD benefit itself.
1Mii NightPair TX Auracast: Who It's For
The 1Mii NightPair TX is a completely different animal. It's a TV audio transmitter — a small black plastic box roughly 4.72" x 3.78" x 0.94", corded, with an external antenna and a bundled remote. You plug it into power, connect your TV over HDMI ARC, Optical/TOSLINK, or 3.5 mm AUX, then either pair it with Bluetooth headphones/earbuds/speakers or start an Auracast broadcast. There's no battery and no speaker, because it isn't meant to make sound on its own.
The connectivity list is where it gets interesting. Bluetooth 6.2, plus LC3 and the full Qualcomm stack: aptX, aptX HD, aptX Adaptive, aptX Low Latency, and even aptX Lossless on the supported-standards list. The practical payoff is latency — with a receiving device that supports the matching codec, dialogue and on-screen action stay closer together, which matters for movies and sports. HDMI ARC also means one cable instead of three, which keeps the back of your TV from turning into spaghetti.
The Auracast side is the genuinely differentiating feature. In Auracast mode, NightPair TX broadcasts the same TV audio to multiple compatible receivers at once. Hearing Aid Mode targets Auracast-compatible hearing aids; Standard Broadcast Mode targets compatible Auracast headphones, earbuds, speakers and receivers. Couples who watch together at different volumes, families, classrooms, churches — that's the use case. The trade-off is real though: receiving devices must support Auracast or LE Audio, and the advertised 100 ft range assumes an open, unobstructed space. Walls and interference will cut into it.
Who should skip it? Anyone who just wants a headset for phone calls. It has no mic, no earpiece, and no battery. It's also not a fix for a TV that lacks HDMI ARC, Optical, or AUX output.
• Best for all-day phone calls → Callez Headset. 8 hours of talk time, dual-mic CVC8.0 noise cancelling, boom mic, and hands-free controls.
• Best for TV audio, movies and late-night viewing → 1Mii NightPair TX Auracast. It's purpose-built to move TV sound to your ears without raising room volume.
• Best for multiple listeners at once → 1Mii NightPair TX Auracast. Auracast broadcast sends one stream to many compatible receivers.
• Best for portability → Callez Headset. 16.74 g, fits in a pocket, runs on its own battery for 8 days of standby.
• Best for range → 1Mii NightPair TX Auracast. Up to ~100 ft open air versus 33 ft on the Callez — though both shrink with obstacles.
• Best for low-latency video sync → 1Mii NightPair TX Auracast. aptX Low Latency and aptX Adaptive are on the spec sheet; the Callez lists aptX HD only.
• Best for connecting two devices at once → Callez Headset. Simultaneous pairing with two phones, tablets or computers.
• Best for hearing-aid users → 1Mii NightPair TX Auracast. Hearing Aid Mode is designed for Auracast-compatible aids.
• Best fit for truckers, drivers, office and field work → Callez Headset. It's the one you wear while doing something else.
• Warranty note: both carry a 2-year warranty, so neither is a short-term commitment.
These aren't competitors — they're two different jobs. If I had to pick one, I'd buy the Callez Headset, because it works standalone the moment you unbox it: charge it, pair it, and you're taking calls. The 1Mii NightPair TX Auracast is the better product for its specific mission, and if you're a hearing-aid user or you watch TV with a partner at different volumes, it solves a problem nothing else here touches. But it needs a TV, a cable, wall power, and a compatible receiver to do anything at all. Buy the Callez for your ears; buy the NightPair TX for your living room.
which earbuds support aptx hd
On these two data sheets, only the Callez Headset is an earbud-style device, and it lists Qualcomm aptX HD. The 1Mii NightPair TX Auracast supports aptX HD as a transmitter codec, but it isn't an earbud — it sends audio to earbuds, headphones or speakers that support the same codec.
Not really. It's built for calls and voice, with 8 hours of talk time and a boom mic, not for stereo movie audio. For TV audio, the 1Mii NightPair TX Auracast is the correct tool — it takes HDMI ARC, Optical or AUX from your TV and transmits it wirelessly.
Yes. It works as a traditional Bluetooth transmitter for headphones, earbuds, speakers and receivers, and it also runs in Auracast mode for compatible Auracast or LE Audio devices. Codec support like aptX Low Latency or aptX Adaptive depends on what your receiving device supports.
Yes — Bluetooth 5.0 pairs with iOS and Android phones, tablets, laptops, computers and PCs, and it can hold two connections at once. Range is up to 33 ft, and a 1.5-hour charge gives roughly 8 hours of talking or 16 hours of music playback.
