These Monoprice Premium Bluetooth™ Hi-Fi Over-the-Ear Headphones use a single 50mm woofer and three 13mm tweeters in each earpiece to deliver superb sound quality across the entire musical spectrum. They feature a frequency response range of 20Hz to 20KHz and a 120dB sensitivity, so you will hear every note with clarity and as much volume as you can handle. As amazing and convenient as Bluetooth connectivity is, you still have to have a phone or music player with you or within Bluetooth range. However, with these Monoprice Headphones, you don't even need a phone or music player. Just plug a micro SD card into the card slot in the right earpiece and listen to your favorite music directly off the card. The headphones have a built-in Lithum-polymer battery with capacity for up to 20 hours of playback/talk time and a whopping 325 hours of standby time.
