For some earphones are what they occasionally use when they need to and most likely those people are fine with the earphones that come with their device. Others are people who depend on their earphones to take them away from their surroundings or keep them motivated. These are people who are traveling, working out, or are working remotely. They not only want great sound, but also great comfort as well. RHA, a company out of Glasgow, UK has sent us their latest earphones, the MA450i. These earphones feature a solid aluminum design, 10mm Mylar drivers, seven interchangeable ear-tips and a fabric braided cable. The MA450i has also been certified for use with iPhone, iPod and iPad devices so you will be able to make and receive calls.
