LDAC Hi-Res Wireless Audio

LDAC support enables higher-resolution wireless playback, with sampling up to 24-bit/96 kHz and a data rate up to 990 kbps. This setup aims to preserve more detail from your digital tracks compared with standard Bluetooth, delivering a spacious, open soundstage that can feel more faithful to the recording.

• Supports 24-bit/96 kHz sampling for detailed highs and balanced mids
• Up to 990 kbps transfer rate preserves more audio data
• Compatible with LDAC, aptX HD, LL, and other codecs for flexible playback

Audiophile DAC & Decoding

The B06Ultra uses an ES9018K2M DAC to decode audio with low noise and wide dynamic range, helping to reproduce subtle textures and instrument separation. This approach appeals to listeners who value a natural, immersive listening experience from lossless files.

• High-quality DAC supports faithful stereo reproduction
• Wide dynamic range enhances instrument imaging and tonal balance

Bluetooth 5.3 with aptX HD & LL

Powered by a Qualcomm Bluetooth 5.3 platform, the unit supports LDAC, aptX HD, aptX LL, aptX, SBC and AAC for versatile wireless listening. The result is a smoother connection with broad device compatibility across modern and older players.

Versatile Connection Options

Connect to powered speakers, A/V receivers, or traditional stereo systems via 3.5 mm, coaxial, or optical outputs. This is a receiver-only device, designed to take Bluetooth audio and deliver it to your existing hardware. Note: This product is a receiver ONLY, NOT a transmitter.

Volume Control & 3D Audio

Adjust listening levels directly on the adapter with the built-in volume control. A 3D audio option can be toggled on or off to broaden the perceived listening space from a standard source.

Dual Antennas & Long Range

Dual antennas and Class 1 Bluetooth technology help sustain a reliable signal, with an indoor range of up to 50 ft and up to 100 ft outdoors in clear line-of-sight conditions.

Real-World Use Scenarios

Turn a bookshelf or floor-standing setup into a flexible wireless hub. Enjoy convenient streaming from phones, tablets, or laptops while preserving your existing speaker investments and room layout.
