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-825D Pro wireless TV hearing assistance and protecting headphone is 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-825D Pro 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.
FEATURES

The unique voice highlighting tech and customized tone adjustment allow people to enjoy TV programs in safe sounds, protecting people’s hearing from the progressive hearing damage caused by watching TV with normal headphones for a long time.
(2) Personal Sound Amplifier A MIC button is designed as an additional & unique feature to help you to temporarily hear what people are talking to you when watching TV without taking off the headphone.

9. Quick Guide

QUICK GUIDE for SM-823D, SM-824D & SM-825D IMPORTANT:

1. The unit will not work with the optical audio if the optical cable is carrying a

Dolby Digital or DTS signal.

In this case, set the Audio Out Format of your TV and TV related AV devices (e.g., cable box/DVD etc) to

PCM to get the unit to work.

2. Three different audio cords: digital optical cord, RCA cord and 3.5mm cord. In the end, only one of these cords is needed to complete the installation.

3. This device is a wireless TV headset as well as a personal sound amplifier. You can find a

MIC ON/OFF

button at the rear of headset. It is designed for hearing impaired people to clearly hear what people’s

talking to him/her nearby when watching TV. Just press MIC ON/OFF button , you can turn this headset to

a personal sound amplifier which could amplify the people’s voice around. When you want to back to

watching TV, just press the MIC button again. When use it as a wireless TV headset, the green working

indicator is on. As a personal sound amplifier, the red MIC indicator is on.

4. We suggest to hook up the transmitter base to the Optical Audio Out port of your TV/Smart TV box/ Cable TV box/Set-top box/DVD/other audio device in priority, for enjoying the super sound quality.

For streaming media watching (Netflix, Amazon Prime Video, etc.), place the transmitter base at least 4 feet away from your smart WiFi TV/WiFi TV box/TV sticks to avoid interference.

SEVEN FREQUENCY ASKED QUESTIONS (FAQ) from marketing statistical analysis:

1.Outside noise overpowers the TV voice.

It is possible that the MIC ON/OFF button at the rear of headset is pressed on inadvertently, in this case the

MIC

indicator is solid red . To back to watching TV, just press the MIC ON/OFF button again or switch off the headset

and then restart with the red MIC indicator off and the green TV receiving indicator on.

2.The connections are correct and in place, but no TV sound is heard or sound cuts in and out.

  1. It is possible that the volume of the audio source is set too low. If you connect

STB/Cable box/DVD etc to the

TV to watch programs, then the audio source is the STB/Cable box/DVD etc. Please use the audio source’s

remote control to set its volume to a sufficient level to ensure a steady sound signal. If you want to mute the TV

sound and only hear from this headset, please use your TV remote control to click

MUTE menu. (For most TVs,

the TV’s speakers are separately controlled from the TV’s audio out).

  1. When do connection with the optical cable, set the Audio Out Format of your TV and TV related AV devices

(e.g., cable box/DVD etc ) to PCM to get the unit to work. ( Settings > Sound
