If you want personal, noise-canceling earbuds for elderly listeners, choose EarFun Air Pro 4; if you need a TV adapter that sends audio to two headphones, choose 1Mii B3+.
For most everyday listening, I’d choose EarFun: it is the actual pair of wireless earbuds, with adaptive noise cancellation, call microphones, and app controls. The 1Mii B3+ is a different kind of product—a Bluetooth transmitter for a TV or other audio source—so it makes more sense when shared, private listening is the goal.
• EarFun Air Pro 4: Its biggest strength is the combination of adaptive noise cancellation, six microphones, and touch-and-app controls; its trade-off is that it is a personal pair of in-ear earbuds, not a TV transmitter for two listeners.
• 1Mii B3+: Its biggest strength is transmitting TV or computer audio to two Bluetooth headphones at once; its trade-off is that it is an adapter, not a set of earbuds, and must connect to an audio source.
• Choose EarFun for individual listening, calls, noise reduction, and Bluetooth use on the move.
• Choose 1Mii for home entertainment when two people want wireless audio from a compatible TV, computer, or console.
The EarFun Air Pro 4 is the more direct choice for someone shopping for earbuds to wear throughout the day. Its adaptive hybrid active noise cancellation is specified at up to 50 dB, and the system is designed to adjust to the shape of the wearer’s ear canal. That points to a useful everyday role: reducing surrounding sound during listening rather than simply sending audio from a television to another device. The exact result will depend on fit and surroundings, but the feature set is clearly focused on personal listening.
For an older listener, the six built-in microphones, AI processing, and Qualcomm cVc 8.0 call technology are relevant because calls are part of ordinary earbud use, not an afterthought. Bluetooth 5.3 supports connections to two devices at once, so a listener can keep a phone and another compatible device connected and switch between them. The stated 55 ms latency is also intended to keep video and game audio closer to sync. The EarFun app adds adjustable EQ, noise-control modes, touch-control assignments, and firmware updates; that gives users options, though it also means some customization involves an app.
Audio format support is broad, including aptX Lossless, LDAC, LE Audio, and LC3, alongside the product’s Snapdragon Sound and Hi-Res Audio claims. A 10-band EQ is available through the app. Those options may matter to listeners who want to tailor sound or use compatible high-fidelity sources, but a person seeking straightforward TV sharing may not need them. The listed design is in-ear with rounded tips and touch controls, so comfort and ease of handling will be personal considerations.
Who should skip it: Skip EarFun if your main requirement is sending one TV’s audio to two pairs of Bluetooth headphones; it is not the transmitter in this comparison.
The 1Mii B3+ is designed to add Bluetooth audio transmission to a TV, computer, game console, or other compatible source. It supports Optical (TOSLINK) and 3.5 mm AUX inputs, giving buyers two common ways to connect home equipment. Once connected, it can send audio to two Bluetooth headphones at the same time. That makes it the more relevant pick for a couple or family who want to watch together without relying on the room’s speakers.
Its aptX support includes aptX, aptX Adaptive, aptX HD, and Low Latency. Those formats are intended to provide quality and reduce delay, particularly for video and gaming, but the exact benefit depends on compatible source and listening devices. The built-in LCD displays connection status, audio mode, and device settings. For someone who would rather see what the transmitter is doing than guess from a sequence of indicator lights, that screen is a practical part of the design. Push-button controls and a volume control are also specified.
The B3+ can pass sound through to a soundbar while headphones are in use, which is useful when one person wants headphones and others prefer room audio. It also lists USB and TF-card media support, an integrated headphone stand, and USB-C power connection. Those extras make it more of a home audio accessory than a simple cable adapter. Its central limitation is just as important: it does not include a pair of earbuds. A buyer still needs compatible Bluetooth headphones or speakers, and the unit needs a wired audio connection to the source.
Who should skip it: Skip the B3+ if you want a standalone pair of earbuds for calls, outdoor listening, or everyday personal use.
• Best for personal listening on the go → EarFun Air Pro 4. It is the earbud option, with wireless Bluetooth connectivity and in-ear design; the B3+ is a home transmitter.
• Best for noise reduction → EarFun Air Pro 4. Its adaptive hybrid ANC is specified up to 50 dB, while the 1Mii’s role is transmitting audio rather than canceling sound around the wearer.
• Best for calls → EarFun Air Pro 4. Its six microphones, AI algorithms, and cVc 8.0 processing are specifically directed at improving vocal clarity during calls.
• Best for two people watching one TV → 1Mii B3+. Dual-link transmission supports two Bluetooth headphones simultaneously, provided the headphones and connection setup are compatible.
• Best for visible connection information → 1Mii B3+. Its LCD shows connection status, audio mode, and device settings.
• Best for a phone and a second device → EarFun Air Pro 4. Bluetooth 5.3 multipoint allows two devices to be connected and switched between.
• Best for flexible wired TV connections → 1Mii B3+. It accepts Optical and 3.5 mm AUX inputs, rather than serving as a Bluetooth earbud pair.
• Best for tuning personal sound and controls → EarFun Air Pro 4. The app provides EQ adjustment, noise-mode selection, and touch-control customization.
The first question is not which name sounds more appealing; it is what device you are actually trying to buy. EarFun Air Pro 4 is a pair of Bluetooth earbuds. The 1Mii B3+ is a Bluetooth transmitter that connects to an audio source and sends its sound to headphones or speakers. They solve different problems, so choosing by feature list alone can lead to the wrong setup.
For an older person who wants an everyday listening device, think about the difference between wearing earbuds and operating a TV accessory. EarFun combines touch controls with an app for adjustments. That can be useful for someone who wants to set noise modes or personalize sound, but app-based options may be unnecessary if simple listening is the only goal. The product sheet does not establish that one control style is easier for every elderly user; comfort with touch controls and apps varies from person to person.

Call needs point more clearly toward EarFun. Its microphone array and call-processing features are listed for vocal clarity, while the B3+ has no earbud microphone feature specified. Conversely, if the priority is shared listening, the B3+ has a distinct advantage that a single pair of earbuds cannot match. For someone searching for “ipx7 waterproof wireless earbuds for elderly,” there is an important limit: neither data sheet supplies an IPX7 rating, so I would not treat either product as confirmed to meet that specific waterproof requirement.
If you are comparing the best with microphone on ear headphones for elderly, note that EarFun is in-ear, not an on-ear headphone, but it does list six microphones and call-focused processing. The B3+ is not a headphone at all. And if the search is simply for Bluetooth earbuds for elderly, EarFun is the relevant product type here; the 1Mii only adds Bluetooth transmission to a compatible audio source.
I would choose the EarFun Air Pro 4 for an elderly listener who wants one personal pair for calls, everyday Bluetooth listening, and noise reduction. Its microphone system and adaptive ANC make it the more complete standalone listening option in this comparison. I’d choose the 1Mii B3+ instead when the real need is shared, private TV listening at home. For the primary use case—earbuds for elderly listeners—I recommend EarFun.
For personal listening and calls, I’d choose the EarFun Air Pro 4 because it is a pair of earbuds and includes ANC and six microphones. The B3+ is better suited to transmitting TV or computer audio to headphones.
Yes. Its dual-link feature is designed to transmit audio to two Bluetooth headphones at the same time. The headphones are separate devices, and the B3+ also needs a compatible wired audio connection to the source.
The 1Mii B3+ is the more suitable choice for that setup. It can send audio to two Bluetooth headphones and supports soundbar passthrough, so headphone listening and room audio can be used together.
No IPX7 rating is provided for either product in the specifications here. EarFun is the only pair of earbuds in this comparison, but the supplied information does not confirm that it is waterproof to that rating.

For home television listening, check which audio output the TV or other source provides before choosing the B3+. Its specified inputs are Optical and 3.5 mm AUX. Also consider whether one or two people need headphones, whether a soundbar should continue playing, and whether the headphones support a compatible Bluetooth audio format. The adapter enables dual listening, but it does not remove the need to supply the headphones separately.
