The SIMOLIO Digital 2.4GHz Dual Wireless TV Headphones are designed to provide hearing protection and assistance for seniors and the hearing impaired. Unlike normal wireless TV headphones, these headphones use voice highlighting and noise cancelling technology to dynamically reduce the TV background sound, making the TV dialogue stand out and allowing you to easily understand the TV dialogue at a safe volume level.
The headphones also feature customizable sound settings, including balance and tone controls and a mono/stereo option, allowing you to adjust the sound to your most comfortable volume level. Additionally, the built-in microphone lets you separately amplify people’s voices nearby, so you don't have to take off your headphones to hear what people are saying to you.
These headphones do not require pairing or experience any sound delay, making them very convenient to use. However, it is important to check the audio output of your TV or related audio source before purchasing to ensure compatibility. The headphones require a Digital Optical (Toslink/SPDIF), RCA, or 3.5mm AUX audio out port.
The under-chin headset weighs 2.04 oz, but for those with sensitive ear canals, SIMOLIO also offers an over-ear design wireless TV headphone SM-825D Pro or wireless TV speaker SM-621D as an alternative. These RF products are not available for pacemaker carrier as well as people with severe hearing loss.
The headphones come with a spare battery and an extra battery charging compartment for convenient charging. They also feature intelligent power saving to conserve battery life. Additionally, the headphones include a personal sound amplifier function designed as an additional and unique feature to help hearing impaired people temporarily hear what people are saying to them when watching TV.
