I honestly just thought I'd be listening to some music at work with these, but boy was I wrong!!It's really simple to make adjustments, such as earbud length (and easily retract when done too!), volume control, play/pause, answer/end phone calls, as well as other phone features like rejecting calls and redial

Nice noise canceling feature

Also the folding arms are another welcome feature which you would only expect from a higher dollar headset

It tells you how much is left in the battery which is a nice feature

The retractable feature is both smart and well-designed as it protects the wires—the most fragile part

The wires to the headphone seem small, but so far they haven't broken (which is longer than some others have lasted in our house).One of my son's favorite features is that it doesn't constantly tell you the battery level.

Some of the coolest features, are the voice dial feature - hello hands free! - and also the vibration when an incoming call comes in

I'm thrilled!BONUS Feature!

The retractable and folding features are a nice addition but weren't a requirement for my purchase

The earbuds are also light, which is a nice feature of this style of headphone, not having such a heavy thing in the ears as with others that dangle with the battery built in to the part that goes in the ear

The BEST feature on this is the sound
