The headphones feature Klipsch's patented oval earbuds, which are supremely comfortable.
There's also an included cable clip, which you'll need to fight cable noise – I found I could hear my heartbeat and breathing while listening to music softly, but it's not an issue with music at normal volumes.
The controls can be used to play/pause, skip tracks, change volume and activate Siri on the iPhone, but Android users won't be able to skip back to a previous track with a triple-click, which is a minor annoyance.
Music sounds effortless with the X6i though, admittedly, it lacks the detail of more expensive headphones.
Most companies rely on cramming in two or more of these drivers in each earbud to get rich, balanced sound, so it's impressive that Klipsch managed the same feat with a single driver.
Audiophiles on a budget should check out the Shure SE215 $99 and bass lovers should look at the Sennheiser Momentum In-Ears.
