OVERVIEW

Would you like to watch television with crystal-clear sound that won’t disturb others in your family? Do you want to avoid hearing damage that could be caused by wearing normal wireless headphones for a long time? SIMOLIO SM-8245 wireless TV hearing assistance and protecting headphone are just made for you.
Apply with the latest 2.4GHz Digital Automatic Frequency-Hopping Spread Spectrum (FHSS) technology, it gives you crystal-clear sound with the freedom of a wireless connection – up to 100 feet without obstacles. You can customize your listening at a most comfortable volume level, via balance and tone controls.
Our voice highlighting and noise cancelling technology dynamically reduce TV background sounds and make TV dialogues stand out. At last you can easily understand the TV dialogues at a healthy volume without worrying about your hearing being damaged.

The SIMOLIO SM-8245 is especially helpful for hearing-impaired people. It overcomes the weakness of regular hearing aids, which amplify both speech and environmental background at the same time. Normal wireless headphones for TV watching don’t help either, they also amplify everything together. Also, over time you’ll keep turning the volume up and up, and that can make your hearing worse and worse. Our hearing protecting headphone solves these problems.

The unique “one-button push” sound amplifier function allows you to hear clearly what people are talking nearby without taking off the headphones.

It’s compatible with both digital and analog audio output ports and suitable for almost all TVs and the set-top boxes on the market.

• Three different audio cables included: digital optical cable, RCA cable and 3.5mm cable. In the end, only one of these cables is needed to complete the installation.
• If your audio source device has an optical audio out port, please connect SIMOLIO to this port preferentially. If not, you can also connect SIMOLIO to the RCA or AUX/3.5mm or other audio out port of the audio source device.

Turn on the Transmitter and Headphones

1. Power the Transmitter (Ref. Fig 2-1)
   Plug the supplied AC adapter into a standard electrical outlet, plug the other end of the AC adapter into the port labeled “DC 5V” on the back of the transmitter.
