Phiaton’s new MS 100 BA ($99) is a pair of in-ear monitor headphones that use balanced armature drivers. While this technology might not be ideal for large headphones, they are an excellent choice for this sort of application. Bundled with the MS 100 BA are a carrying pouch and four sets of eartips. The red cable includes a mic and track control button but, unfortunately, iOS-friendly volume controls are absent.{/exp:char_limit}
