How do you plan to use your wireless headphones? Each set of wireless headphones has its own strengths and weaknesses, so it's best to choose a set that fits your specific needs. Bluetooth headphones are a must for on-the-go listening, but they generally don't offer the sound quality of bulkier models designed for home use. For watching TV, headphones with a closed back are a good choice; they can block outside noise (as discussed below) and also keep the sound coming through the headphones from leaking out to disturb others.
Do you want to shut out other noises? If you want to listen to music in the office or in a crowded bus station, you may find it helpful to have headphones that block out ambient noise. Any headphones with a closed, over-the-ear design will somewhat muffle outside noise -- but to truly put the world on mute, you'll need noise-canceling wireless headphones. On the other hand, if you want to be able to hear the phone ring or keep track of your kids playing, then headphones with an open back will let you hear your music without shutting out the outside world.
What are your preferences for fit? Comfort in headphones is largely a matter of personal preference. Some people prefer smaller on-ear headphones, while others like the enveloping feeling of an over-the-ear model. Some like open-back headphones because they stay cooler, while others don't mind a little extra warmth. The size of your head also matters. While many sets of headphones are adjustable, users with large heads may still find some pairs tight enough to cause a headache, while those with small heads may have trouble keeping them in place. If you can, try the headphones on before you buy, or purchase them from an online retailer with a good return policy.
Is aptX a must for Bluetooth headphones? Several of our Best Reviewed Bluetooth headphones and some newer mobile devices use aptX audio compression technology to boost their sound quality. However, unless you have an aptX-enabled device, paying a premium for this technology won't improve your headphones' performance. Moreover, we found that many Bluetooth models -- including our Best Reviewed budget pick, Skullcandy Grind Wireless (Est. $85) -- sound very good (for Bluetooth) even without aptX.
