The TA003S/TA004S silent audio system is the desktop upgrade of the TA003/TA004 series, featuring a 6-channel transmitter with Bluetooth and XLR professional audio input. The upgraded headphones include built-in bass-boost speakers for better sound quality and a removable logo panel for easy custom branding.
Whether you’re leading a yoga flow, guiding meditation, running a breathwork session, hosting a fitness class, or creating a silent party experience, the right audio setup can make a noticeable difference. Quiet settings need focused, uninterrupted sound, while larger or more dynamic events often require more flexibility for different groups and listening preferences. The Retekess TA003S transmitter paired with TA004S silent disco headphones brings clear wireless audio, reliable transmission, and multi-channel flexibility together in one solution, making it well suited for wellness spaces, fitness sessions, silent parties, and a wide range of other real-world applications. Here are real customer photos showing how customers are using the system in everyday environments.
In a group setting, one soundtrack rarely fits everyone. Each transmitter supports one channel, and up to 6 independent channels can be created by using up to 6 transmitters together. This makes the system well suited for multi-group audio setups. Each TA004S headphone features a color-coded LED for fast channel identification, so switching stays simple and distraction-free.
Sound quality shapes the full breathwork and meditation experience. This system delivers enhanced bass with warm, full sound without being overpowering. By connecting your phone via Bluetooth, you can stream music or sound effects directly to the transmitter with minimal setup.
Every package includes a headset microphone for clear, real-time instruction. For added flexibility, you can also choose a bundle with a wireless microphone or purchase one separately. Simply connect the mic to the transmitter to mix your voice with background music, allowing clear instruction while background audio continues to play.
Use Bluetooth to play background music, and connect a professional microphone through the XLR input for live instruction. Two audio sources can be played simultaneously, so you can guide your class while background music continues smoothly.
Heavy headphones can become uncomfortable by the end of a 90-minute yoga flow. The TA004S headphones are ultralight, with a padded adjustable headband and breathable leather ear cups. They also truly fold, making them easy to pack between retreats. The over-ear design and noise isolation help block outside sound, turning almost any space into a calm listening zone. Each headphone has its own volume control, so every student can set a level that feels right.
The TA003S desktop transmitter runs for up to 10 hours in High Power mode or 20 hours in Low Power mode on a full charge, and the TA004S headphones also deliver 12 hours of continuous listening. Each headphone features a display showing both battery level and active channel at a glance, while the Type-C port keeps charging convenient.
One transmitter. Two power modes. Coverage that adapts to your space.Low Power (150 m / 492 ft): Ideal for small studios, quiet zones, and indoor sessions.High Power (300 m / 984 ft): Great for larger outdoor spaces such as beach yoga, forest retreats, and festival fields.A single transmitter can support a large number of headphones, making it easy to scale your class as needed.
With custom logo branding available, TA004S headphones help your studio, retreat, or wellness brand look more polished and professional. It’s a simple way to make your brand more visible, create a more memorable participant experience, and leave a stronger impression long after the session ends.
