Creative has evolved into a value audio brand that delivers a lot of bang for your buck, so it's no surprise that its $79 WP-350 on-ear Bluetooth headphones sound very good given the price.
On the other hand, on-ear headphones aren't for everyone due to the way they sit flush against your ear -- some may find them more comfortable than others. In the case of the WP-350s, I found them fairly comfortable and experienced no problems wearing them on a 30-minute commute every day to and from work.
Still, they're not quite as comfortable as competing on-ear wired headphones like the Bose OE2i or the models, and my ears did get a little steamy on warmer days.
More importantly, I was able to achieve a fairly tight seal on my ears, and these headphones do a decent job of shutting out the outside world. I can't say I felt incredibly cool wearing them, but their design is attractive enough, with a subtle design punctuated with a glossy finish on the outer portion of the earcups.
Again, there's nothing terribly fancy about these headphones, but they seem well designed and should hold up fairly well to being carried around daily. No case is included, unfortunately, and while the cups do fold flat, the headband can't fold up like the band on the more expensive.
One thing I appreciate the most in travel is the large buttons, particularly the volume buttons that the designers conveniently placed on the inner lip of the right earcup, so they're easily found by touch. You shouldn't have to fumble around or remove the headphones to raise and lower volume or answer and end calls, and yes, there's a built-in microphone. Of course, if you're using a smartphone to stream audio, you'll most likely use the virtual buttons on the device rather than the hard buttons on the headphone to control audio playback.
