Built-in microphone/control module. If you’re not fond of pulling your phone out of your pocket, some headphones have control modules and mics on the wire or built into the headphones that let you do a number of things. You can answer phone calls, access Siri or Google Now, and control your music. Always check what the controls are and see if they match your preferences.
Not all earphones are workout-friendly, though; don't assume your earphones will handle what you throw at them unless they're fitness-oriented earphones, or at least are explicitly listed as water- and sweat-resistant. Really pricey earphones can be as fragile as really pricey headphones, and you don't want to accidentally ruin a $200 pair with ear sweat.
Unfortunately, there have been reports that the neckband build quality isn’t the best, as the rubber casing starts peeling off after a few months of usage. The Bose Connect app also doesn’t offer many customization options and doesn’t provide an EQ, unlike the highly customizable Sony WI-1000X Wireless. Nevertheless, these are versatile, comfortable earbuds that are likely to please, especially for commute and travel.
Premium audiophile company Master & Dynamic took a break from ear-melting home theater systems to drop a pair of true wireless earbuds. You’ll pay handsomely for them, but the Master & Dynamic MW07 Plus offer some of the best sound quality you’ll find in a pair of earbuds. You could mistake them for stones thanks to the unique designs on the acetate chassis, which are handmade. Because of that, no two sets of MW07 buds are ever alike.
The active noise cancellation is decent, but it’s not adjustable at all and may cause “eardrum suck” for some people (you can read more about this phenomenon in our best noise-cancelling headphones guide). Because of the vented earbud design, the Pro earbuds don’t provide much noise isolation without the ANC activated, but they still produce some mild occlusion effect. With battery life of four and a half hours, they won’t last a cross-country flight or a full workday without a charging break. The Pro earbuds are water resistant, but the design is far less secure for high-impact activities than that of the Powerbeats Pro and less durable than that of the IP55-rated Jabra Elite 75t. While we like that Apple did away with the tap-based controls, the squeeze controls are fiddly (we often play/paused when we wanted to skip tracks) and still lack volume controls (which both the Jabra Elite 75t and Powerbeats Pro have).
Besides the rugged factor, earphones are also much better for staying on your head while you're in motion. A good set of headphones will feel comfortable when you're sitting or walking around, but when you start running or biking they can easily shake free of your ears. Fitness-oriented earphones often have stabilizing fins built in to them to ensure that they'll stay in place no matter what you do at the gym.
