Noble Audio Sceptre Transmitter

Wireless Audio Transmitter with USB-C Simplicity

The Sceptre is a plug-and-play Bluetooth audio transmitter designed to add wireless streaming capability to any device with a USB-C port. By connecting directly to the host's USB-C output, this transmitter delivers audio to Bluetooth headphones, earbuds, or speakers without replacing existing wired gear. Built around the latest Bluetooth 5.4 standard, it provides a stable connection with reduced power consumption compared to older revisions. The Sceptre is the right choice for listeners who want to upgrade their current setup to wireless without buying new source hardware.

High-Resolution Codec Support and Modern Bluetooth Stack

What sets this transmitter apart is its broad codec compatibility. Support for LDAC enables transmission of high-bitrate audio that preserves more detail than standard Bluetooth codecs, while aptX Adaptive dynamically adjusts bitrate and latency based on content type. AAC and SBC round out the format support, ensuring compatibility with virtually any Bluetooth receiver on the market. The inclusion of A2DP, AVRCP, and HFP profiles means the Sceptre handles stereo audio streaming, remote control commands, and hands-free voice communication through a single device.

Connectivity and Platform Support

Universal compatibility is a core design priority. The USB-C male connector plugs directly into modern laptops, tablets, and smartphones, while the unit draws operating power from the host — eliminating the need for separate batteries or charging cables.

• Input Connector: USB-C male — direct plug-in to host device, no adapter required
• Power Source: USB-C bus-powered — no internal battery, no external charger
