Equipped with the latest SoC "QCC5181" and compatible with high-quality sound codecs such as LDAC and aptX Lossless

Although it is palm-sized, it is equipped with the latest SoC "QCC5181" and supports various high-quality sound codecs.
Featuring a quad-core processor architecture and dual-core Qualcomm Kalimba DSP audio processor running at 240MHz, it has powerful computing power for advanced and complex audio algorithms and tasks. It also supports Snapdragon Sound, which provides an immersive and lossless audio experience.
BT11's LDAC transmission uses next-generation LE Audio technology and also supports aptX Lossless. Together, these features provide a high-quality Bluetooth audio experience that delivers exceptional wireless sound quality.
*To use Snapdragon Sound, pairing with Snapdragon Sound-compatible Bluetooth headphones is required.

Compatible with the latest smartphones and game consoles, providing lossless sound quality just by plugging it into your device.

BT11 supports LDAC, 96kHz/24bit aptX Adaptive, aptX Lossless on devices such as the iPhone 15 series, PlayStation 5, and Nintendo Switch. It also includes LE Audio, which reduces latency across the audio chain to as low as 50ms, delivering higher quality sound and a more stable audio connection. PC users can also enjoy high-resolution Bluetooth audio by simply plugging it into their device.
*LDAC transmission currently supports 48kHz/24bit, but a future upgrade will enable 96kHz/24bit transmission.
*If your computer has access to other audio devices, please manually select BT11 as the output device in the audio settings.

Long and clear communication range

To improve the BT11's Bluetooth communication capabilities, we adopted PDS (Passive Double Star) antenna technology, which is the most advanced optical access system. Despite BT11's small body, it greatly improves Bluetooth communication range and maintains a more stable and efficient connection.
PDS antenna technology:
Communication is possible over 50 meters when no one is present, and over 35 meters when there are people (when using LDAC)
Common antenna technologies:
Communication is possible up to 20 meters when no one is present, and 10 meters when there are people present.
