I bought this radio to take out running and for it's small size for overseas trips. It didn't say, but it also receives FM stereo. The sound quality is fair, but becomes excellent when used with high quality headphones or connected to a good stereo amp. The AM section is also very good and has excellent selectivity and sensitivity. I damaged the headphone socket when I forced the removal of the headphone plug. I recommend twisting the plug as you remove it if doesn't come out easily. As a retired electrical engineer, I took it apart and fixed the socket and was also pleasantly surprised at the circuit design.
I bought this armband radio as I wanted to start exercising; and music helps me to get the most out of my exercise routine. The radio stations have great reception. The radio is very easy to use and a quality product. I would highly recommend this to anyone who enjoys exercising to music.
