Description
C1 USB-C to 3.5mm TRRS Audio Adapter: Keep Your Headphones in Service
The SchoolPHONES® C1 adapter turns the 3.5mm plug on any SchoolPHONES® headphone or headset into a USB-C plug. It was made for schools that own K6s, BKs and first-generation LPJ and LPJm headphones with a 3.5mm cable and are moving to Chromebooks, tablets and laptops that only have USB-C. Plug the headphone into the C1, plug the C1 into the device, and the headphones keep working. No new headphones, nothing goes to the landfill.
Key Features:
- USB-C to 3.5mm TRRS: straight USB-C plug on one end, 3.5mm (1/8in) TRRS socket on the other. Stereo sound and the microphone both pass through.
- CTIA* wiring: the same standard every SchoolPHONES® headset uses, so it works with all of our headphones and media headsets, and with most other CTIA/ASH headsets.
- Soft TPE body, 3.5in long: the flexible thermoplastic-elastomer body bends instead of cracking, and the short length keeps the strain off the device’s USB-C port.
- Light blue with the SchoolPHONES® logo: easy to spot in a classroom cart and easy to match to the headphones.
- Bundle price: $5.00 when added to a K6s or BKs headphone order. Pick it on the headphone’s page.
- Pack sizes: 1 pack $5.00, 10 pack $45.00, 50 pack $200.00.
Why Choose the C1 Adapter?
- Upgrade instead of replace: K6s, BKs and first-generation LPJ and LPJm headphones with a 3.5mm cable work on USB-C devices for a fraction of the price of new headphones.
- Protects the device: the adapter takes the plugging and unplugging, not the computer’s port.
- One adapter, every SchoolPHONES® product: compatible with the whole range, including the K6, BK, LP and LPJ series.
