If you want a clip-on receiver for wired headphones and access to Auracast broadcasts for exercise, choose Avantree AuraGo; if you need to send audio to two Bluetooth headphones or speakers, choose Yunseity LE502.
I’d choose AuraGo for the more flexible listening setup: it can receive audio from a phone or compatible Auracast source and feed wired headphones. LE502 is the more focused pick when dual-device transmission is the priority. Neither is itself a pair of headphones, so your existing listening gear matters.

Avantree AuraGo vs Yunseity LE502 at a Glance
• Avantree AuraGo’s biggest strength: It works as a Bluetooth receiver for wired headphones and can also join compatible Auracast broadcasts. Trade-off: It requires headphones with a 3.5 mm input and does not connect to hearing aids.
• Yunseity LE502’s biggest strength: It can transmit audio to two Bluetooth headphones or speakers at once. Trade-off: aptX Adaptive is preferentially supported with a single connection, and the connected device must support that codec too.
• Choose AuraGo if you want a portable receiver for wired headphones or want to listen to compatible Auracast broadcasts.
• Choose LE502 if your main goal is transmitting audio to two Bluetooth listening devices from a source it can connect to.
AuraGo is a receiver, not a set of headphones. Plug wired headphones or earbuds with a 3.5 mm AUX connector into it, then pair the receiver with a compatible phone, tablet, laptop, or Bluetooth-enabled TV. That makes existing wired headphones usable for wireless listening, including music, calls, and videos. It also supports Auracast broadcasts, which can be useful in places such as gyms, classrooms, or other venues that provide a compatible broadcast.
Its clip-on design suits someone who wants to carry a small receiver while moving around, rather than replace their headphones. AuraGo supports Bluetooth 5.4, LE Audio, LC3, aptX Adaptive, and other listed audio standards. Its Auracast discovery can use auto-scan or the Avantree app, and firmware upgrades are supported. For exercise, those features make it a reasonable option if you already have wired headphones you like and want a receiver-based setup. It is not itself a pair of lightweight over-ear headphones.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Skip AuraGo if your headphones lack a 3.5 mm input, or if you need a transmitter that connects directly to two Bluetooth headphones at once. It also does not pair with or connect to hearing aids. Its usefulness for Auracast depends on having a compatible broadcast nearby; the receiver cannot create one.
Yunseity LE502: Who It's For
LE502 is a Bluetooth transmitter. Its standout feature is dual-stream transmission: it can connect to two Bluetooth speakers or headphones at the same time, using the same codec. That makes it the more natural match for shared listening, such as two people using separate headphones with a source device. It supports aptX Adaptive for a single connection when both the transmitter and the receiving headphones or speakers support it.
The LE502 also identifies audio-coding status with indicator lights. Its listed codecs include aptX Adaptive and aptX HD, among others. The product information describes it as driver-free for certain computer operating systems, but the operating-system details are incomplete, so I would not assume support for every computer. It is a transmitter, not a receiver for wired headphones and not a pair of headphones.
For exercise, LE502 makes sense only if your intended setup is to transmit audio from a source to compatible Bluetooth listening devices. It does not offer the same stated wired-headphone receiver and Auracast-broadcast functions as AuraGo. If your priority is a compact receiver for your own wired headphones, or joining a venue’s Auracast broadcast, I would look at AuraGo instead.
• Best for using wired headphones with a Bluetooth phone or tablet → Avantree AuraGo. It accepts headphones or earbuds with a 3.5 mm AUX plug and receives Bluetooth audio.
• Best for joining compatible Auracast broadcasts → Avantree AuraGo. It can scan for nearby broadcasts or use the app to find and select a channel.
• Best for sending audio to two Bluetooth headphones or speakers → Yunseity LE502. Dual-stream transmission is its clearest advantage.
• Best for exercise with wired headphones you already own → Avantree AuraGo. Its clip-on receiver design and 3.5 mm output offer a way to keep using those headphones without a wired connection back to the phone.
• Best low latency on-ear headphones for exercise → Neither product on its own. These are adapters, not headphones. AuraGo supports low-latency wireless listening in its stated use cases, but your headphone choice and compatible devices still matter.
• Best sleep headphones for exercise → Neither. Neither product is a sleep-headphone design, and neither includes headphones. Choose between them based on the audio connection you need, not on an unlisted fit or comfort feature.
• Best for a single aptX Adaptive link → Yunseity LE502, with a condition. The receiving device must also support aptX Adaptive; its documentation says that codec is preferentially supported in single-connection use.
• Best for people who need hearing-aid connectivity → Neither. AuraGo explicitly does not support hearing aids, and no such feature is listed for LE502.
I’d buy the Avantree AuraGo for exercise if I already had wired headphones with a 3.5 mm plug and wanted a portable receiver that also supports Auracast listening. Its two roles make it the more adaptable fit for that setup. I’d choose the Yunseity LE502 instead if sharing audio with two Bluetooth headphones or speakers were the deciding need. That is a real advantage, but it is a narrower one.
FAQ
Can I use Avantree AuraGo with wireless headphones?
AuraGo is designed to connect to wired headphones or earbuds with a 3.5 mm AUX plug. Its listed use is receiving audio from a phone, PC, transmitter, or Auracast source and sending it to connected wired headphones.
Yes. LE502 supports transmission to two Bluetooth headphones or speakers at the same time, using the same codec. Its documentation says aptX Adaptive is preferentially supported for a single connection when the receiving device also supports that codec.
AuraGo is described as supporting low-latency wireless streaming for music, calls, and videos. LE502 lists aptX Adaptive and provides coding-status indicators, but codec support depends on the connected device; the available details do not establish that either setup will have less delay in every pairing.
There is no single answer based on these features alone. Check the current price on Amazon using the page’s button, then compare it with your actual need: AuraGo for wired-headphone receiving and Auracast, or LE502 for transmitting to two Bluetooth listening devices.
