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.

*LDAC supports 96kHz/24bit. More features will be updated later.

Tiny body Large core

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.

*Snapdragon Sound requires pairing with Bluetooth headphones that also support Snapdragon Sound.

The savior of iPhone15 series/PS5/Switch is here

Plug and play, lossless audio at your fingertips

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. 

Computers can also enjoy high-res Bluetooth audio

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.

Hear with better clarity Hear at further distances

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.

Next-gen Bluetooth 5.4

The next step in connection

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.

Two simultaneous connections One shared sound

The BT11 supports simultaneously connecting to two receiving devices, allowing you to easily enjoy high-quality Bluetooth audio together with your friends and family. Create more beautiful moments by immersing yourselves in binge-watching movies or TV dramas.

*The BT11 has no physical button. After connecting to one device, you can enter the pairing states again through the FIIO Control APP to connect to the second device simultaneously.

*The BT11 will not affect the Bluetooth function of the device itself. 

Expanded functionality through app Continuously upgraded

Connect to the FIIO Control App and easily control the device and access functions such as simultaneous pairing to two devices. The BT11 will also be continuously upgraded via over-the-air (OTA) updates, including: LC3, volume adjustment, indicator light control, channel balance adjustment, and pairing lists – stay tuned!

*When connecting to the FIIO Control APP for the first time, please make sure the BT11 is in pairing mode (i.e., red and blue lights flash alternately), and Bluetooth is turned on.

Functional and beautiful Having it all

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.

BT11 supported devices

Supports iPhone15 series and other USB Type-C iOS/iPadOS devices, Window/macOS computers, PS5, and Switch.

*Due to too many customized versions of Android devices and non-standard interface protocols, the above table is not comprehensive. We will continue to update compatible devices in the future. If your device is not on the table, but it supports outputting through the BT11 after testing, please contact us. We will timely update the support list on the sales page.
