Those are capabilities, not guaranteed improvements: devices need matching hardware and software, and manufacturers choose which features to implement.
What is Bluetooth LE Audio?
LE Audio is an audio architecture that operates over Bluetooth Low Energy radio. Traditional Bluetooth audio, often called Classic Audio, uses Bluetooth Classic radio. LE Audio depends on LE Isochronous Channels, introduced in Bluetooth Core Specification 5.2. The Bluetooth SIG completed the LE Audio specification set in July 2022, allowing products seeking LE Audio support to be qualified. Bluetooth SIG’s LE Audio overview explains the feature set.

“Regular Bluetooth” is therefore not a single interchangeable mode. A phone and headphones must both implement compatible audio features. LE Audio is also not another name for Auracast: LE Audio is the broader architecture, while Auracast is a defined broadcast-audio configuration built on it.

1. LC3 gives manufacturers more sound-quality and power choices
LE Audio includes LC3, or Low Complexity Communications Codec. The Bluetooth SIG says listening tests found LC3 could provide better audio quality than SBC, the codec included with Classic Audio, even at a 50% lower bit rate. The comparison is the SIG’s account of those tests, not a guarantee that every LE Audio product will sound better than every Classic Audio product.
#1 Best Overall
- 2-in-1 Charging Case and Phone Stand: Enjoy hands-free viewing without the hassle. Simply open the back panel of the case, place your phone on the stand, and catch up on your favorite shows—watching while traveling has never been easier!
- Strong and Smart Noise Cancelling: Reduce noise by up to 42dB with an advanced active noise cancelling system. With adaptive technology, soundocre P30i detects external sound and automatically selects a level of noise cancelling optimized for your ears.

- Powerful Bass: Unleash deep, punchy bass with soundcore P30i noise cancelling earbuds' 10mm drivers, amplified by the soundcore exclusive BassUp technology for an immersive, robust audio experience.
- Long-Lasting Convenience: Enjoy up to 10 hours of playtime (6 hours with ANC) on a single charge, and up to 45 hours with the case (25 hours with ANC). A quick 10-minute charge provides 2 hours of use, perfect for your on-the-go lifestyle.
LC3 lets manufacturers make tradeoffs between audio quality and power use. The chosen settings, implementation, and product design affect the result; LE Audio does not promise that a particular headset will use less battery or sound better in every situation. Manufacturers may add optional or custom codecs alongside the required LC3 support.
2. Multi-Stream Audio can improve how wireless earbuds work together
Multi-Stream Audio supports multiple independent, synchronized audio streams between a source—such as a phone—and one or more audio devices. That gives true wireless earbud designers a way to send separate synchronized streams to the left and right earbuds, rather than relying on one earbud to relay audio to the other.
The Bluetooth SIG identifies improved stereo imaging and better voice-assistant use as potential benefits. They depend on the product’s implementation; the feature does not ensure that every pair of LE Audio earbuds will deliver the same experience.
Rank #2
- Powerful Bass: soundcore P20i true wireless earbuds have oversized 10mm drivers that deliver powerful sound with boosted bass so you can lose yourself in your favorite songs.
- Personalized Listening Experience: Use the soundcore app to customize the controls and choose from 22 EQ presets. With "Find My Earbuds", a lost earbud can emit noise to help you locate it.

- Portable On-the-Go Design: soundcore P20i true wireless earbuds and the charging case are compact and lightweight with a lanyard attached. It's small enough to slip in your pocket, or clip on your bag or keys–so you never worry about space.
- AI-Enhanced Clear Calls: 2 built-in mics and an AI algorithm work together to pick up your voice so that you never have to shout over the phone.
3. Auracast enables one source to serve many listeners
Auracast broadcast audio allows a compatible source to send audio streams that many compatible receivers can join. That creates options for sharing audio with several people or listening to audio from a public display or venue system. A broadcast can be open or closed with a passkey, according to the Bluetooth SIG’s Auracast webinar FAQ.
Auracast is optional, even on LE Audio devices. A product may support LE Audio without transmitting or receiving Auracast broadcasts, so check the specific function in each device’s specifications.
4. LE Audio adds a standards-based route for hearing aids
LE Audio includes hearing-aid support, and Android’s developer documentation describes Hearing Aid Profile support for calls and VoIP. That can give compatible hearing aids and other audio devices a defined way to work with supported phones.

Compatibility still depends on the particular hearing aid, phone hardware, operating-system build, and supported profile. Google documents built-in LE Audio support at Android 13 (API level 33), but that version-specific platform statement does not establish support on every Android device or accessory. Check the documentation for both products. Android’s LE Audio documentation describes its platform support.

5. Broadcasts can make accessibility and language choice more flexible
A venue or broadcaster can offer separate Auracast streams, such as different language tracks, for listeners with compatible receivers. This can support more flexible listening than a single shared audio feed. Broadcasts may be public or access-controlled, and a listener needs a compatible receiver and the information or setup needed to select the intended stream.
The benefit depends on deployment: the transmitter must provide the relevant streams, receivers must support Auracast, and the venue or service must configure the system appropriately. The capability alone does not mean a particular location already offers it.

How LE Audio and Classic Audio differ
| Aspect | Classic Audio | LE Audio |
|---|---|---|
| Radio and architecture | Bluetooth Classic radio | Bluetooth Low Energy radio; uses LE Isochronous Channels |
| Codec | Includes SBC; other codec support depends on product | Includes LC3; optional or custom codecs may also be supported |
| Multiple synchronized streams | Does not provide LE Audio’s Multi-Stream Audio feature | Supports independent, synchronized streams when implemented |
| Broadcast listening | Does not provide Auracast broadcast audio | Can support Auracast, but the feature is optional |
| Hearing-aid support | Not the hearing-aid capability introduced with LE Audio | Includes a hearing-aid support path; device and profile compatibility still matter |
| Compatibility | Works with compatible Classic Audio devices | Requires compatible LE Audio implementations; Classic Audio support on an LE Audio product is optional |
Classic Audio remains useful, and a product may support both modes. But a Classic Audio headset is not automatically compatible with an LE Audio source, and an LE Audio label by itself does not tell you which optional features are present. The Bluetooth SIG addresses backward compatibility in its LE Audio FAQs.
What to check before buying or connecting devices
- Confirm LE Audio on both ends. Check the phone or other source and the headphones, hearing aids, or receiver; support in one does not establish compatibility with the other.
- Look for the exact feature. Verify LC3, Multi-Stream Audio, Auracast transmit or receive, or Hearing Aid Profile support as relevant to your use.
- Do not rely on “Bluetooth 5.2” alone for Auracast. Auracast needs specific Core 5.2 features as well as the Public Broadcast Profile. The SIG recommends checking the manufacturer’s explicit feature claims.
- Check software and device-specific details. An operating-system version can include platform support without guaranteeing that every device, build, or accessory exposes the feature.
