pod with a built in microphone is included and provides control over volume and music navigation (the control pod is only compatible with Apple products such as the iPhone and the iPod). Klipsch also handily provides a hard case for carrying the X11i as well as an airline adapter.
When it comes to audio performance the X11i impresses with its versatility and dedication to staying neutral. The trebles are drenched with Klipsch’s signature warmth when it comes to tracks such as Adele’s Melt My Heart to Stone. But the earphones are equally adept at rendering the clear, chiming guitar lines in Buckethead’s Sail On Soothsayer.
Underpinning the neutral tone of the X11i earphones are balanced mids. The mid-range frequencies do not bleed over or subdues the highs, but still have a weighty presence in the mix. Adding to the realism of the audio, the X11i also does a great job of preserving the unique timbre of the instruments on the track. It also has good imaging and a decent soundstage. Listening to orchestral tracks with the X11i was a joy.
Bass frequencies for the X11i are up to par. Good transient response makes the percussion instruments sound good. But the low frequencies lack impact for certain tracks. If you are a fan of bass heavy music genres, such as RnB for example, you may find the X11i to sound somewhat thin in the lower registers.
On the whole the X11i is a great pair of headphones that showcase balanced armature units to the full. Great balanced sound with a good soundstage and attention to detail should make extremely attractive to audiophiles who love classical or orchestral music. The $569 price-tag however may put off some buyers.
