LDAC is finally here Since the release of the BTA30 Pro, FiiO has been relentlessly trying to enable LDAC on more devices. Despite facing challenges like high costs and lack of original manufacturer support, FiiOs determination paid off and they 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. 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, when used with headphones that also support this. 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 the audio settings. Hear with better clarity and longer distances In order to enhance the Bluetooth transmission capability of the BT11, FiiO spared no expense and adopted advanced PDS antenna technology. Despite the limited space of the BT11, they 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. Full Bluetooth codec support Not only are the LDAC and SBC codecs supported, but the BT11 also supports all Qualcomm aptX codecs including: aptX Adaptive, aptX Lossless, aptX, aptX HD, aptX Low Latency. So you can fully enjoy having access to a wide variety of audio codecs. *AAC transmission not supported yet 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.
