Key Features

• Multi-Channel Reception: Receives 4 dedicated, color-coded FM frequencies (72.500 MHz, 72.100 MHz, 72.900 MHz, 74.700 MHz), allowing easy switching between multiple audio channels.
• Wireless Freedom: No antenna on the headphone, providing a clean and comfortable listening experience.
• Long Battery Life: Approximately 18-19 hours of listening time with about 5 to 5.5 hours of charging time.
• Superior Sound Quality: Frequency response of 20-20,000 Hz and sensitivity of 100dB ±3dB for clear and rich audio.
• Classroom-Friendly Design: Powered by an internal NiMH battery, making it safe and easy to use in educational settings.

Important Notes

• Compatibility: The W901-Multi headphone must be used with the W900-Multi transmitter. If adding to an existing 6-person Listening Center, ensure you have an additional AC power adapter (W980) and a 6-way charging cable, as one AC power adapter can charge only up to 6 headphones.
• Shipping Restrictions: Due to the inclusion of a Lithium-Ion Battery, when shipping outside of the continental U.S., such as Alaska, Hawaii, Puerto Rico, or any destination on an island (e.g., Avalon, CA), it must ship via 2nd Day Air ONLY.
