Sony Quality Infrared Wireless Audio Headphone Set [1FP-10 HEADPHONES MDR-510]

Description

SONY INFRARED MODULATOR TMR-IF1O EMITTER and 1FP-10 HEADPHONES MDR-510
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This High Quality Vintage Sony Stereo Headphone and Transmitter/Emitter System  was purchased by us a number of years ago. It is still in good condition and works very well. (has minor scratches and blemishes, see photos) They are very sturdy and we found them to be a very comfortable fit for the ear.  The frequency response of the earphones is excellent, and they work well in any room anywhere up to about (20 feet x 20 feet) from the base unit, with no problem.  They interface well to most stereo systems via standard RCA type jacks and common audio cables. They have a heavy duty power supply unit, upon which you can mount the infrared transmitter unit. (The IR transmitter does not need to rest on top of this unit, but can be located up to about six feet away.) The IR transmit unit  (the standing tubular structure) has a number of IR elements, and this makes the unit work well at various angels in our experience. The unit is easily pointed to the area where you will be wearing the headphones most of the time.

In these days of Wi-Fi connected devices, Internet of Things, Google and Alexa devices listening to your conversations all the time.  Please be  assured that Audio content that you transmit with this device will be staying within the confines of your own household. This Sony IR system DOES NOT  use BlueTooth, Wi-Fi or any other wireless transmissions that can be easily picked up by nearby wireless receivers.  It uses  line of sight infrared rays that are confined to the area of a room in your home, and will not transmit your audio to other neighbors or out over the Internet for all to intercept.
This unit was an era when Internet, WI-Fi and Bluetooth were not available. So if you would like a little old fashioned privacy and and a sense of security, you might want to give this high quality Japanese manufactured system a try.

The units were cleaned with a very mild alcohol and soap solution (damp not wet), and are in very good condition. The headphone unit is powered by inserting 1ea AA battery in each side of the left and right ear supports below the red IR sensor. Unlatch the door at the end and insert each battery. See Photos. (Batteries are not included with this offer; a quality alkaline battery is recommended.)
Please see photos for condition. The units have been electrically tested and work well.
