With a Lightning a USB-C headphone you plug the headphone directly into the Lightning port (on Apple devices) or USB-C port (on Android devices). A standard headphone plug is an analog connection while this creates a direct digital connection. The headphones are powered by your phone (they use only a little bit of battery power) and have an integrated DAC (digital-to-analog converter) that's usually superior to the DAC in your phone.
We use a commercially-available Bluetooth high-def interface with an S/PDIF output to test the Bluetooth output of four flagship phones. This way, we’re able to record test signal output and compare the datasets with our in-house analysis software. We kicked the tires on a 96kHz/24-bit test file to see how Bluetooth handled high-bitrate music, as well as normal 44.1kHz/16-bit files to see how each codec treated CD-quality streaming audio. We then measured the recorded sample against the original file. We used both lograrithmic sine sweeps, and complex signals like square waves in order to provide a more realistic set of tests for how people actually use Bluetooth headphones.
While the data signal containing Bluetooth audio is compressed, headphone and earphone manufacturers have found ways to enhance the signal to compensate for its deficiencies in a way that even audiophiles can appreciate. We've included some wireless options here, but if you're really keen on cutting the cord, check out The Best Wireless Headphones. And if you want to go completely wireless (with no cord at all connecting the two earpieces), check out The Best True Wireless Headphones—just keep in mind these are about as far from over-ear headphones as you can get.
If you won’t compromise on sound quality—and you’re willing to pay for it—the Bang & Olufsen Beoplay E6 may be for you. It doesn’t come cheap, but the Beoplay E6 is one of the best portable wireless models we’ve ever tested. In addition to sound quality, it has design perks including magnets that clip the earpieces together (and automatically turn the headphones off) for easy transport, a braided cable for added durability, and water resistance, according to the manufacturer.
This type combines advantages of earbuds and in-ear headphones – depending on the environment and requirements of the user, they provide passive noise reduction for quality mode (conversation or active music listening) or they give control over the sound environment around user in comfort mode (stand by or background voice/music listening).
Over-ear and on-ear headphones effectively block out outside sounds, allowing you to hear your music or whatever else you're listening to crisply and without distraction. Over-ear headphones are sometimes known as full-size headphones because they completely envelop the wearer's ear. This results in what's known as passive noise reduction, which makes these some of the most-preferred headphones available. The only drawback is that your ears and the skin around your ears can get warm and sweaty. These are usually the heaviest type of headphones.
