Hi,
If you usually use the headphones to enjoy music and songs while doing work on the personal computer then you don't actually need wi-fi headphones. The wired ones definitely will do the job if you need to connect them to your own smart phone or tablet. In most cases wired headphones will be a cheaper selection in comparison to the wireless headphones.
For those physically active throughout the day wireless headphones will be a better option. The very bad thing in relation to wireless headphones is they may encounter interference from different wi-fi products around But it's good to know that Bluetooth headphones are safe from that.
If you're a bit suspicious regarding the quality of sound among those two [http://www.bestheadphonesunder100.net/|types of headphones], you've got nothing to worry about.
