If you want open-ear wireless earbuds with adaptive noise cancellation and a clip-on fit for webinars, choose EarFun Air Pro 4+; if you need a TV transmitter for private or shared listening with compatible receivers, choose 1Mii NightPair TX Auracast. These products solve different problems: one is a pair of earbuds, while the other sends audio from a TV or another compatible source to wireless listening devices.
• EarFun Air Pro 4+ strength: Clip-on, open-ear earbuds with hybrid drivers, Bluetooth 6.0 and adaptive noise cancellation; trade-off: they are personal earbuds, not a TV audio transmitter.
• 1Mii NightPair TX Auracast strength: HDMI ARC, optical and AUX inputs, plus Bluetooth and Auracast transmission; trade-off: it needs a powered audio source and compatible receiving headphones, earbuds, speakers or hearing aids.
• Choose EarFun for personal listening, calls and webinar use in a compact ear-worn format.
• Choose 1Mii to route TV audio to wireless devices, privately or as an Auracast broadcast for multiple compatible listeners.
The EarFun Air Pro 4+ is a set of wireless clip-on, open-ear earbuds. Its C-shaped bridge sits around the ear rather than inserting an earpiece into the ear canal. Each earbud weighs 5.5 grams, and the design combines a soft silicone bridge with nickel-titanium memory wire. That may appeal to someone who dislikes the sensation of in-ear tips or wants a fit that stays attached to the ear. The stated flex testing is a design detail, not a guarantee that any particular fit will suit every wearer.
For webinars, the useful distinction is that these are earbuds you wear, not a box that connects to your television. Bluetooth 6.0 provides wireless connectivity, while app, touch and voice controls offer several ways to manage them. Their adaptive hybrid noise cancellation is designed to respond to surrounding noise, with cancellation described as reaching up to 50 dB. That feature may help when you want to reduce environmental sound, though the open-ear form and noise control are separate design elements; the sheet does not establish how much outside sound a particular user will hear in every setting.
The audio system combines a 10 mm composite dynamic driver with a balanced-armature driver. Support listed for aptX Lossless, LDAC, LC3 and LE Audio gives the earbuds a broad set of audio-format options, although the available codec depends on the connected device and setup. The EarFun Audio App also supports translation across more than 100 languages, with real-time and face-to-face modes. Who should skip it: Skip the EarFun if your main need is to transmit TV audio to several listeners or connect through HDMI ARC, optical or AUX; it is an earbud set, not a transmitter.
The 1Mii NightPair TX Auracast is a corded TV audio transmitter. It connects to a compatible source using HDMI ARC, optical/TOSLINK or 3.5 mm AUX, then sends audio wirelessly through Bluetooth or Auracast. The choice of input gives it a practical role in different home entertainment setups: use the connection supported by the TV, projector or media player, rather than expecting the transmitter to work as a standalone listening device.

Its Auracast option is the main reason to consider it over ordinary personal earbuds. In broadcast mode, one transmitter can send the same audio to multiple compatible receivers. The receiving devices must support Auracast or LE Audio; an existing Bluetooth headset is not automatically an Auracast receiver. The product also lists a hearing aid mode for compatible Auracast hearing aids and a standard broadcast mode for compatible headphones, earbuds, speakers and receivers. That can suit a household, classroom or other shared-listening setting where people need their own receiving device.
For private listening, the transmitter can send TV sound to compatible Bluetooth headphones, earbuds, speakers or hearing aids. Its listed codec support includes LC3 and several aptX formats, including aptX Low Latency and aptX Adaptive. The stated aim is to keep audio closer to the on-screen action when the receiving device supports the corresponding codec; it is not a promise of identical performance with every device. An external antenna is specified for a range of up to approximately 100 feet in open, unobstructed conditions, with walls and interference potentially reducing that distance. A remote and buttons handle basic operation from a seat. Who should skip it: Skip the 1Mii if you want a pair of earbuds to wear directly for webinars or listening on the go; this transmitter needs a separate audio source and listening device.
• Best fit for personal earbuds → EarFun Air Pro 4+. Its clip-on, open-ear design is worn directly, with no TV transmitter involved.
• Best fit for connecting a TV to wireless audio → 1Mii NightPair TX Auracast. It accepts HDMI ARC, optical/TOSLINK and 3.5 mm AUX audio inputs.
• Best for Auracast group listening → 1Mii NightPair TX Auracast. It can broadcast to multiple compatible receivers, provided those devices support Auracast or LE Audio.
• Best for adaptive noise cancellation in earbuds → EarFun Air Pro 4+. Its hybrid ANC adjusts to external noise, with cancellation specified up to 50 dB.
• Best for a clip-on alternative to in-ear earbuds → EarFun Air Pro 4+. The C-shaped bridge holds the earbuds around the ear instead of placing them in the ear canal.
• Best for TV dialogue with compatible low-latency equipment → 1Mii NightPair TX Auracast. It supports relevant codecs, but the receiving device must support the matching option for that benefit.
• Best for webinar use in a personal listening setup → EarFun Air Pro 4+. It is the wearable option of these two, while the 1Mii is built to transmit audio from connected equipment.
• Best for translation features in the companion app → EarFun Air Pro 4+. The listed app features include real-time and face-to-face translation across 100+ languages.
Before choosing the EarFun, think about fit and your preferred listening style. Its clip-on design avoids an ear-canal earpiece, but that does not make it a universal fit. The bridge is intended to flex and rotate around the ear; people who specifically want traditional in-ear earbuds, or a device designed to transmit television sound, should look elsewhere. Also consider whether the listed codec support matters for your phone or computer. A codec can only be used when the source device supports it, so the feature list alone does not guarantee a particular connection or sound result.
The 1Mii’s listed range is an approximate maximum in an open, unobstructed environment. A larger room may be convenient, but walls, wireless interference and the receiving device can change the actual range. Likewise, low-latency support depends on compatible codecs at the receiving end. If your main concern is watching TV without disturbing someone nearby, the transmitter’s private-listening purpose is a close match; if the goal is to wear earbuds during a webinar, EarFun is the more direct fit.
My Verdict
I would choose the EarFun Air Pro 4+ for personal listening and webinars. Its clip-on form, open-ear placement, adaptive noise cancellation and app features make it the more relevant of these two products for someone seeking wearable earbuds. The 1Mii NightPair TX Auracast is my pick for routing TV audio to compatible devices, especially when private or shared Auracast listening is the goal. They are not substitutes, so I’d decide based on whether I need earbuds or a transmitter.
No. It is a corded audio transmitter that connects to a compatible TV, projector or media player and sends audio wirelessly. You need separate compatible headphones, earbuds, speakers or hearing aids to listen.
Yes, in Auracast mode it can broadcast the same audio to multiple compatible receivers. Those devices must support Auracast or LE Audio; ordinary Bluetooth compatibility alone does not establish that they can receive an Auracast broadcast.
For wearing earbuds during a webinar, I’d choose the EarFun Air Pro 4+, since it is the personal listening device in this comparison. The 1Mii is intended to transmit audio from connected equipment, and the supplied specifications do not describe it as a webinar headset.
Check that your audio source has an HDMI ARC, optical/TOSLINK or 3.5 mm AUX output, and that your receiving device supports the wireless mode and codec you intend to use. For multi-listener Auracast broadcasting, each receiver needs Auracast or LE Audio support.
