OVERVIEW

FEATURES

(1) Wireless TV Hearing Assistance and Hearing Protecting Function

Soften the background sound, make the TV conversation stand out, help the

hearing impaired people to understand the TV clearly, solve the problem that

regular hearing aid cannot do. 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.

The unique “one-button push” sound amplifier function allows you to hear clearly

what people are talking nearby without taking off the headphones.

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.

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.

(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.

SM-825D Pro

(12) Headphone Designed with Auto Power Off Function for Power

Saving

automatically.

(13) Audio Sharing Function

SIMOLIO headphone to share audio with your buddy .

SEVEN F REQUE NCY ASKE D QUEST IONS (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).

2) 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 > Digital Audio Out Format >
