If you want wireless earbuds with active noise cancellation for big ears, choose EarFun Air Pro 3; if you need a USB-C Bluetooth transmitter to connect compatible headphones, choose eppfun Le Audio USB. These solve different problems, so the right pick comes down to whether you need the listening device itself or a way to send audio to one.
For someone shopping for with microphone bluetooth headphones for big ears, the EarFun is the direct option; the eppfun is a connection accessory, not a pair of headphones.
• EarFun Air Pro 3: wireless in-ear earbuds with noise cancellation, six microphones for calls, multipoint Bluetooth, and up to 40 hours of stated battery life; the trade-off is that the provided specifications do not give earbud dimensions or a fit guarantee for larger ears.
• eppfun Le Audio USB: a USB-C Bluetooth transmitter with Bluetooth 5.4, multiple supported audio codecs, and Auracast broadcast capability; the trade-off is that your headphones must support the same codec to use it, and it does not include headphones.
• Choose EarFun if you want a self-contained pair of wireless earbuds for listening and calls.
• Choose eppfun if you already have compatible Bluetooth headphones or earbuds and need a transmitter for a phone, game console, or other supported device.
• For gaming headphones for big ears: the EarFun has a stated 55-millisecond latency figure, while eppfun offers low-latency codec support when the connected headphones also support the matching standard.
The EarFun Air Pro 3 is the more straightforward choice if you need the earbuds themselves. Its 11-millimeter dynamic drivers are described as producing deep bass, clear mids, and crisp highs. The model also includes noise cancellation, while its six microphones and Qualcomm cVc 8.0 processing are designed to pick up speech and reduce background and wind noise during calls. That combination makes it a practical fit for someone moving between music, calls, and video without adding a separate transmitter.
Bluetooth 5.3 supports simultaneous connections to two devices, so you can keep two paired devices connected and switch between them. The stated 55-millisecond latency is relevant for games and video, where audio lag can be distracting. Its battery information gives up to 40 hours of playtime, though the provided details do not clarify how that figure is divided between the earbuds and charging case. The specs also list a 10-meter Bluetooth range.
For shoppers with larger ears, there is an important limit to what the listed information can tell you: these are in-ear earbuds with rounded tips, but no tip sizes, earbud dimensions, or large-ear fit details are provided. I would not treat the “for big ears” search as a fit guarantee. Skip the EarFun if you need an over-ear headset or a USB transmitter for headphones you already own.
The eppfun Le Audio USB is a transmitter, not a listening device. It is designed to send audio from a USB-C connection to wireless headphones or earbuds. Its Bluetooth 5.4 connection and Qualcomm 5181 chip are intended to provide a current wireless link, while the listed codecs include LDAC, aptX, aptX Adaptive, aptX Lossless, SBC, and LC3. LED indicators show the active working status.

Auracast is the distinctive feature here. In broadcast mode, the transmitter can send audio to multiple receiving devices at once, provided they are Auracast-compatible. That could suit shared listening to a movie or program when several people have compatible receivers. Skip the eppfun if you need a new pair of headphones, built-in microphones, or a product that works without checking codec compatibility.
• Need earbuds for everyday listening and calls → EarFun Air Pro 3. It is a complete pair of in-ear headphones with six microphones and call-focused noise reduction.
• Already own Bluetooth headphones and need a transmitter → eppfun Le Audio USB. It sends audio to a separate compatible listening device.
• Want to connect two devices at once → EarFun Air Pro 3. Its Bluetooth 5.3 multipoint feature supports simultaneous connection to two devices.
• Want to share a broadcast with multiple listeners → eppfun Le Audio USB. Auracast is designed for one-to-many transmission, but each receiver needs the appropriate compatibility.
• Care about a stated gaming or video latency figure → EarFun Air Pro 3. Its listed latency is 55 milliseconds; the eppfun supports low-latency codecs, subject to matching support in the headphones.
• Need microphone-equipped headphones → EarFun Air Pro 3. Its six microphones and cVc 8.0 processing are intended for clearer calls. The eppfun is a transmitter and does not supply a microphone or headphones.
• Want to use high-quality codecs → eppfun Le Audio USB, if your headphones support them. Its codec options include LDAC and several aptX formats; the actual connection depends on the receiving device’s supported standards.
• Shopping specifically for big ears → consider the type of product first. EarFun is the only one here that goes in the ear, but the provided specifications do not establish a fit for larger ears. The eppfun does not address ear fit at all.
I’d choose the EarFun Air Pro 3 if I wanted a complete wireless listening option, especially for calls, multipoint use, and the stated 55-millisecond latency. For big ears, I would still check whether its in-ear shape suits me rather than assume the fit from the product name or search term.
I’d choose the eppfun only if I already owned compatible headphones and specifically needed a USB-C transmitter or Auracast broadcasting. It adds connectivity options, but it cannot replace a headset.
For shoppers looking for with mic head phones for big ears, my recommendation is EarFun—with the clear caveat that the listed fit details do not confirm suitability for larger ears.
Buying Considerations
Compatibility deserves particular attention with the transmitter. A long codec list can be useful, but it does not mean every connected headphone will use every codec. The receiving headphones must support the same standard. If you are buying it for a console, laptop, phone, or handheld device, confirm that the connection and platform suit your setup before deciding. The listed compatible devices include gaming consoles, laptops, and smartphones, with platform support also described for Windows, Linux, Apple, Android, Switch, and PS5.
Think about the listening situation, too. EarFun’s multipoint feature is useful if you commonly move between two connected devices, and its microphones make it the more relevant choice for calls. The eppfun is more specialized: Auracast could help with shared listening, but only when the receivers are compatible. Neither product’s listed information establishes a particular fit for large ears, so fit should not be inferred from the “big ears” use case alone.

No. It is a USB-C Bluetooth transmitter that sends audio to wireless headphones or earbuds. You need a separate receiving device to listen.
Not necessarily. Its listed codecs include LDAC, aptX options, SBC, and LC3, but the headphones must support the same standard for the corresponding codec to work. Check compatibility before relying on a particular audio or latency feature.
The EarFun is the relevant choice for calls because it includes six microphones and Qualcomm cVc 8.0 processing intended to reduce background and wind noise. The eppfun transmitter does not include headphones or a microphone.
The provided EarFun information identifies an in-ear design with rounded tips but does not list dimensions or tip sizes. The eppfun is a transmitter, so it has no ear fit; your separate headphones determine that.
