The Shure SE315 in-ear earphones work well for both personal and professional use. Concentrate on your workout at the gym, or mix professional music, with a noise isolating system that easily blocks up to 37dB of outside noise. With Shure's MicroDrivers, you also have the benefit of exceptional sound quality as well as noise isolation. For comfort, these earphones fit completely inside of the ear, with no tear-shaped overhang like you often see with other earphones or earbuds. With these Shure earphones, the cable fits right around the ear for a perfect fit every time. These also come with the benefit of a 64-inch cable, giving you plenty of room to work with, whether you're jogging, working, or simply want to listen to your favorite tunes in bed. The cord is also very durable, reinforced with Kevlar, so you worry less about tangling or damaging your cord. With an MMCX connector, you are also able to replace ear wiring pieces individually should you require a replacement. This ensures you never have to replace the entire unit itself should the worst occur. In addition to being interchangeable, these Shure earphones also come complete with a myriad of accessories, such as: universal fit foam sleeves, three sizes of the sleeves to ensure a comfortable fit, and an earwax cleaning tool so your music never sounds cloudy to your ear. An instruction manual is also included, should you need help changing out the earpieces or selecting the right size to fit your needs. Easily turn on the noise isolation feature to block out unwanted sounds. Whether you're walking down the street, don't want to hear conversation or chatter around you, or want to block out simple ambient noise, the noise-canceling feature on these headphones do the trick. Along with Shure's patented MicroDrivers, not only are these in-ear earphones comfortable to wear and aesthetically pleasing, you're guaranteed that you have the best sound quality all of the time as well. These earphones are expressly designed for all-day wear and are always comfortable, especially with the included different ear sleeve sizes.
