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-828D1 / SM-828D2 wireless TV hearing assistance and protecting earphone 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-828D1 / SM-828D2 is especially helpful for hearing-impaired people.

The magnetic charging stand allows you to place and charge the earphones conveniently.
