OpenAudio's Full Line of Streaming Audio Products Support LE AUDIO

China, 5th Aug 2024 - OpenAudio's streaming audio products are primarily characterized by their WIFI AUDIO capabilities. The current lineup includes three products: the HOLO-WHAS, which supports up to 8 zones, the single-zone HoloHome Streamer+, and the single-zone HoloHome Streamer.

At first glance, they may seem to be in a different league from Bluetooth audio, but in reality, they are not. OpenAudio's products support both Bluetooth and WIFI audio, combining the strengths of both.

Moreover, OpenAudio's Bluetooth functionality always supports the latest technology. While most similar products only support classic Bluetooth audio, OpenAudio has already embraced LE AUDIO.

Differences and Integrations Between WIFI and Bluetooth Audio

	Distance	Frequency	Speed	Security
Bluetooth 4.0	Typically 30 Feet (DependsOn Device, Maximum 200Feet)	2.4 Ghz	25 Mbps	128-bit encryption
Wireless B	Max. 150 Feet	2.4 Ghz	11 Mbps
Wireless G	Max. 170 Feet	2.4 Ghz	54 Mbps
Wireless N	Max. 230 Feet	2.4 Ghz AND 5 Ghz Can operate on MultipeSignals (MIMO)	130 Mbps (in theory up to 450Mbps with 3 antennas)
Wireless AC (Gigabit wi-Fi)	Max. 230 Feet (but with greater throughput at simila!distance to Wireless N)	2.4 Ghz AND 5 Ghz Can operate on MultipeSignals (MIMO)	In theory up to 1.3 Gbps (eachdata stream can run up to 433Mbps)	WPA2 security (AES 256-bitkey-based encryption)
WiFi Direct (Competing withBluetooth for communication from devices to PCs backwardscompatible with legacy Wi-Fi devices)	Max 656 Feet		Up to 250 Mbps	WPA2 security (AES 256-bitkey-based encryption)

The advantage of WIFI is its high available bandwidth, which can transmit higher bitrates, meaning better sound quality. For example, with Gigabit Wi-Fi, the bitrate can be as much as 52 times that of Bluetooth.

Another aspect is the transmission range. For instance, WIFI can reach up to 230 feet, while Bluetooth typically only reaches 30 feet, giving WIFI AUDIO a 7.67-fold gain over Bluetooth audio in this regard.

Q: So, what are the advantages of Bluetooth?

A: It is relatively easy to set up, and it has a memory function for the second connection.

Now, let's take a look at what LE AUDIO is and what experiences and improvements it brings to consumers.

LE Audio is the new generation of Bluetooth audio technology standards. The "LE" stands for Low Energy. LE Audio operates on low-energy Bluetooth radio, not only enhancing the performance of standard Bluetooth audio but also enabling many new use cases, offering consumers innovative ways to enjoy and share wireless audio.

In fact, there are many advantages of LE AUDIO over classic Bluetooth audio, such as ultra-low power consumption, support for broadcasting, multi-stream audio, audio sharing, and hearing assistance features, applied in real life:

1. Smaller Bluetooth products in size;

2. Longer standby time for Bluetooth products;

3. Lower Bluetooth transmission latency;

4. Better sound quality, better stereo experience;

5. Lower resource requirements;

6. LE Sync Channel: BLE transmits audio streams;

7. New transmission architecture for TWS earphones;

8. Music sharing with one phone and multiple earphones;

9. Quick switching between multiple Bluetooth devices;

10. Making the use of voice assistant services more seamless;

11. Audio sharing based on personal or location-based;

12. A new generation of hearing assistance systems;

13. A 50% lower bitrate;

14. Hearing aid function, helping users with limited hearing to hear clearly.

LC3 is a new generation of efficient Bluetooth audio codec that can be used in the LE Audio profile, capable of achieving lower Bluetooth transmission latency and providing a better wireless experience for users.

Main technical features of LC3:

1. Modular audio conversion codec;

2. Offers a wide range of available bit rates;

3. Supports frame intervals of 10 ms and 7.5 ms;

4. Supports various bit depths: 16, 24, and 32 bits per audio sample;

5. Supports an unlimited number of audio channels;

6. Supports various sampling rates: 8kHz, 16kHz, 24kHz, 32kHz, 44.1kHz, and 48kHz.

1. Under the same conditions, the bitrate can be halved; LC3 can achieve the effect of the SBS 345K white paper bitrate with an output bitrate of 192Kbps.

2. Naturally, the latency is lower; the size of a frame of data is only 55% of the previous, reducing the latency by 45%.

From the chart provided by Force Technology/SenseLab, it can be seen that the SBS 345Kbps bitrate actually does not reach the effect of LC3 at 160Kbps.

We can see that while JUKE AUDIO is still celebrating the addition of Bluetooth functionality, OpenAudio has already implemented LE AUDIO. Let's also take a look at how OpenAudio's HOLO-WHAS outperforms JUKE AUDIO's JUKE-8.

It can be seen that OpenAudio's HOLO-WHAS completely outperforms JUKE AUDIO's JUKE-8 in 16 aspects. Its price also has a significant advantage (JUKE-8 is priced at $1688, while HOLO-WHAS is only priced at $1200), making HOLO-WHAS extremely cost-effective.

HoloHome Streamer+ also supports LE AUDIO, while similar products like WIIM AMP do not. Let's also take a look at how OpenAudio's HoloHome Streamer+ completely outperforms WIIM AMP.

Taking the signal-to-noise ratio (SNR) as an example, HoloHome Streamer+ is 32dB higher than WIIM AMP. In the audio field, a 3dB difference is worth a lot, so what does a 32dB difference mean? Therefore, choosing HoloHome Streamer+ also means choosing quality.

HoloHome Streamer also supports LE AUDIO, while similar products like WIIM PRO PLUS do not. Let's also take a look at how OpenAudio's HoloHome Streamer completely outperforms WIIM PRO PLUS.

In many cases, bass is the soul of an audio playback system. It's unclear why WIIM Pro Plus only supports the outdated 2.0 system. Although it has narrowed the gap with OpenAudio's HoloHome Streamer in SNR and THD+N, it exposes a major problem in the lack of bass output.
