As for sound quality, in our tests the Sesh outperformed the vast majority of true wireless earbuds in its price range. The bass was more intense and, especially with hip-hop, could sound a bit louder in the mix than you might expect, but it didn’t blur or muffle male voices like a lot of the competition did. The higher frequencies were a little rolled-off, so “s” sounds were a bit softer and had an airier “sh” quality rather than a sharp “s” quality. But overall, for a pair that typically costs $60, the Sesh sounded fantastic.
You don’t need to worry about being caught in the rain, either, because these earbuds are IP55 rated, which means they can take dust, rain, and some light sweat without breaking. You can tote the Elite 75t to the gym if you are doing a mild workout; however, if you sweat heavily, you may want to consider our workout headphones pick, Jabra’s Elite Active 65t, which has an IP56 rating. Although Jabra backs the Elite 75t with a two-year warranty against water and dust damage, this wireless earbud model isn’t covered for intense sweating. The Active edition is more sweat and dust resistant, but those earbuds are a little bigger and have a shorter battery life per charge.

A number of wireless models have rechargeable batteries. And if they run out of charge, the headphones don't work at all, though some models can also function without power using a detachable audio cable. There are also a few headphones on the market that can be powered with replaceable alkaline batteries, but we recommend the rechargeable option instead of tossing batteries out again and again.
The best earbuds for noise cancellation that we’ve tested so far are the Bose QuietControl 30. If you usually find in-ears a bit uncomfortable, then their earbud fit may be the solution you've been hoping for. They have a well-balanced, bass-rich sound, and their neckband design ensures your music is always at arm’s reach. They have very good noise cancelling and also hardly leak any sound, which makes them a good choice for use while commuting or at the office.
Total harmonic distortion: True, headphones with lower actual total harmonic distortion (THD) will sound better than those with higher THD. But the quoted THD numbers -- "less than 1 percent" -- aren't helpful in predicting sound quality. Listen to recordings of simply recorded acoustic guitar to assess the distortion of one set of headphones versus another. Some will sound appreciably cleaner than others.
Technically speaking, earbuds are not earphones, as they don't enter your ear canal. Instead they sit just outside of it, where it's easy to become loose and cause problems when it comes to accurate stereo imaging (in which both ears get the same amount of audio) and bass response. Earphones, meanwhile, fit in the ear canal and form a seal inside your ear, blocking outside noise while piping sound directly into your ears. They're much smaller and lighter than headphones, since they don't need to fit on or over your ears and don't require any outside support (though some have stiff wire sections or flexible fins to keep them in place without getting in the way). Plus they won't mess up your hair.
