The RHA MA450i earphones are noise isolating earphones equipped with an inline remote and microphone for the Apple iPod, iPhone or iPad. The RHA MA450i’s housing is machined from aircraft grade aluminum while the copper cable is covered in braided fabric for minimal tangling and durability. RHA’s signature aerophonic chamber design used in the MA150 and MA350 is also used on the MA450i, producing natural sounds with much clarity compared to traditional earphone designs. Noise isolation in the MA450i is handled by 7-pairs of interchangeable silicone ear tips of varying sizes including a double flange pair. Each ear tip is made of two different kinds of high-quality silicone: a firmer piece for the inner chamber and a softer piece for the flange to comfortably fit inside the ear canal. The MA450i is available in a black or white version and is backed by RHA with a 3-year warranty.
