The NEXUM VOCE+ is the world’s first dedicated Auracast™ transmitter — a compact device that transforms how we broadcast and share wireless audio. Whether you’re a content creator, educator, business professional, or someone who wants to share audio with a room full of listeners, VOCE+ makes it effortless.

This guide covers everything you need to know about VOCE+: what it does, how it works, and why it matters.

What Makes VOCE+ Different?

Traditional Bluetooth can only connect to one or two devices at a time. VOCE+ changes that entirely. Using Bluetooth LE Audio and Auracast™ broadcast technology, VOCE+ can transmit audio to an unlimited number of receivers simultaneously — with crystal-clear quality and ultra-low latency.

Think of it as your personal radio station that broadcasts directly to Bluetooth headphones, hearing aids, and earbuds — all without pairing.

Key Features at a Glance

• Dedicated Auracast™ Transmitter: Purpose-built for broadcasting audio to unlimited listeners within a 30-meter range
• Dual Gain Modes: Switch between Normal Mode (0dB) and Boost Mode (+3dB) to match your environment
• Built-in High-Performance Microphone: Ideal for podcasting, vlogging, live streaming, and guided tours
• Universal Connectivity: USB-C and 3.5mm aux connections work with virtually any audio source
• Bluetooth 5.2 LE Audio: Next-generation codec support for lossless wireless audio quality
• Ultra-Low Latency: Minimal delay for real-time audio applications
• Compact and Portable: Take it anywhere — from classrooms to conference halls

Normal Mode vs. Boost Mode

VOCE+ features a convenient switch that lets you toggle between two gain modes depending on your environment:

• Normal Mode (0dB gain): Standard output for close-range scenarios like one-on-one conversations, small meetings, or recording in quiet environments
• Boost Mode (+3dB gain): Enhanced amplification designed for larger spaces, noisy environments, or listeners with hearing needs. The extra gain ensures your audio comes through clearly even at distance

Simply flip the switch to match your situation — no app or software configuration required.

How VOCE+ Works

Plug VOCE+ into any device with USB-C or 3.5mm output — your laptop, TV, phone, tablet, or gaming console. VOCE+ instantly begins broadcasting via Auracast™, allowing any compatible receiver, earbuds, or hearing aids within range to tune in.

There’s no complicated pairing process. Listeners simply scan for the broadcast and connect — just like tuning into a radio station, but with Bluetooth-quality audio delivered straight to their personal device.

Real-World Applications

For Content Creators

Use VOCE+ as a wireless broadcast microphone for recording podcasts, vlogging, or live streaming. The built-in mic captures clear audio, while the optional 3.5mm extension mic input allows professional-grade recording.

For Educators and Tour Guides

Broadcast your voice to an entire classroom or tour group. Every participant wearing Auracast™-compatible earbuds receives your audio in real-time — no complicated setup, no interference from ambient noise. Switch to Boost Mode for larger venues.

For Hearing Accessibility

With Boost Mode (+3dB), VOCE+ amplifies and clarifies audio for individuals with hearing needs. As hearing aids increasingly support Auracast™, VOCE+ serves as the bridge between any audio source and next-generation hearing devices.

For Home Entertainment

Connect VOCE+ to your TV and broadcast audio wirelessly to multiple headphones. Watch movies late at night without disturbing others, or let the whole family listen with their own preferred earbuds.

For Business Events and Conferences

Set up VOCE+ at your podium or presentation station and broadcast to every attendee’s phone or earbuds. Ideal for multilingual events, silent presentations, or any scenario where traditional speakers fall short.

Pair VOCE+ with AERO Earbuds

For the ultimate Auracast™ experience, pair your VOCE+ transmitter with NEXUM AERO earbuds. AERO is purpose-built for Auracast™ reception, delivering seamless connectivity at distances up to 30 meters with exceptional sound quality. Together, VOCE+ and AERO create a complete wireless audio ecosystem.
