The MPR-AF1 is a pocket portable radio with headphones. It includes a long-life rechargeable battery, that does not require you to inconveniently replace batteries while out on the go. The MPR-AF1 is your personal radio it is a great for receiving your local sports radio, NPR, and your favorite music. The MPR-AF1 has an internal ferrite bar antenna that in-itself has extreme sensitivity, but our engineers went a step beyond the internal ferrite antenna, intelligently designing the headphone jack to also act as an external antenna jack as well. This allows your headphones to be used as a long external antenna (while still providing crisp stereo audio). A true feat of engineering. More than just a mini am fm radio walkman, the MPR-AF1 includes a built-in clock, and includes features such as storing your favorite channel presets or allowing you to lock the keypad (to ensure your channel is locked in, while you are out moving on the go). The MPR-AF1 includes two different styles of headphones, allowing you to pick the most comfortable way to use your pocket radio. The convenient LCD display shows the exact am or fm stereo station that you are listening to. This allows you to easily see and tune to your favorite radio station. Fully charge your battery before the first use. BTECH is proud to be in the USA, which allows you to have the best available local support for any issue that may arise.
