Tired of yoga room noise bleeding into your meditation session? Wish you could give each student their perfect soundtrack without anyone else hearing it? Overwhelmed by tangled gear at yoga?

Meet the Retekess TA003S & TA004S desktop silent audio system. Built for yoga instructors, meditation guides, breathwork coaches, and wellness event organizers, it pairs a desktop transmitter with lightweight headphones to create a private sound environment for every participant.
In a group setting, one soundtrack never fits everyone. The TA003S transmitter supports 6 independent channels(use with 6 transmitters) — more than enough for multi-group audio. Each TA004S headphone features a color-coded LED for instant channel identification. Switch seamlessly. No dropouts. No distractions.
Sound quality shapes the entire breathwork and meditation experience. The system delivers enhanced bass audio through speakers — warm and rich without being overpowering. By wirelessly connecting your phone via Bluetooth, you can directly transmit music or sound effects to the transmitter. Prefer a wired connection? The RCA input works too.
Simply plug your microphone (sold separately) into the transmitter. Your voice and music will blend automatically. You can move around the classroom, weaving among students—your voice will always be clear and uninterrupted.
Heavy headphones become unbearable by the end of a 90-minute yoga flow. The TA004S headphones are ultralight, featuring a padded adjustable headband and breathable leather ear cups. They truly fold — compact enough to toss in a backpack between retreats. The over-ear design and noise isolation seal out external sound, turning any space into a sanctuary. Each headphone has its own volume control, so every student dials in exactly what works for them.
Our desktop silent audio system ta003s transmitter runs 12 hours on a full charge. The TA004S headphones also deliver 12 hours of continuous listening. The headphones feature a digital display showing both battery level and active channel at a glance. The Type-C port supports charging anytime.

One transmitter. Two power modes. Every space covered.
Low Power (100m / 328ft): Perfect for small studios, quiet zones, or indoor sessions
High Power (300m / 984ft): Covers expansive outdoor spaces — beach yoga, forest retreats, festival fields
Plus, a single transmitter supports unlimited headphones, making it effortless to scale your class.
The TA004S headphones feature a removable logo panel for easy customization. Add your studio logo, and your students become walking ambassadors for your community.
