LDAC, aptX Lossless transmitter | Qualcomm QCC5181 flagship platform

The BT11 enables devices like the iPhone 15 series, PS5, and Nintendo Switch to support  LDAC, aptX Adaptive at 96kHz/24bit, and aptX Lossless - ushering in a new era of lossless audio transmission. LE Audio is present and also helps by reducing latency across the entire audio chain to as low as 50 milliseconds, providing higher-quality sound and a more stable audio connection experience. 

The savior of iPhone15 series/PS5/Switch is here

Plug and play, lossless audio at your fingertips

While the BT11 is only about the size of a button, it is equipped with Qualcomm’s flagship Bluetooth chip, the QCC5181. It features a quad-core processor architecture and two 240MHz Qualcomm Kalimba audio DSPs, providing powerful computational capabilities for advanced and complex audio algorithms and tasks. It also supports Snapdragon Sound*, which delivers an immersive lossless audio experience.

Tiny body Large core

Laptops and computers plug and play to catch up on TV shows and movies, and listen to music, which will impress you with higher-level sound quality.

*If the computer has access to other audio devices, please manually select the BT11 as the output device in audio settings.

Computers can also enjoy high-res Bluetooth audio

In order to enhance the Bluetooth transmission capability of the BT11, we spared no expense and adopted advanced PDS antenna technology. Despite the limited space of the BT11, we significantly improved the Bluetooth transmission range while ensuring a more stable and efficient connection.

Hear with better clarity Hear at further distances

Thanks to the QCC5181 platform, the BT11 supports the latest Bluetooth 5.4 version. It provides more stable connections, longer transmission ranges, and overall system performance improvements - all at lower power consumption.

Parts list

After four years of hard work LDAC is finally here

Since the release of the BTA30 Pro, we have been relentlessly trying to enable LDAC on more devices. Despite facing challenges like high costs and lack of original manufacturer support, our determination paid off and we have now achieved a breakthrough.

In contrast to the CSR8675, the LDAC transmission supported by the BT11 not only boasts higher computational power but also utilizes the next-generation LE Audio technology and even supports aptX Lossless. These features come together to create a high-end Bluetooth audio experience that delivers exceptional wireless sound quality.

Both of the available classic black and silver colors are elegant choices that easily match your style. The gold-plated Type-C port is both wear and oxidation-resistant, ensuring your connection is stable and reliable for years to come.
