These are great and I'm surprised by the sound these buds can produce! was skeptical of the inked series buds fitment but they do not fall out as easily as you expect. With the battery and controls on a neck piece, this allow the buds to feel lighter in the ear and less cumbersome than the BT headsets with battery/controls on the buds. This allows the user to easily use one headphone if they're in an environment that requires one ear to be free. Something to be mindful of, the neck piece has a relaxed fit, meaning if you're too active they will fall and yank the buds out you ear. Walking or just moving around a work space will sit just fine.
Controls are simple, to volume up/down, you just have to press plus or minus button. To change tracks you have to hold plus or minus. Play and pause, press the center, and to power on/off, you just have to hold the center. Though changing tracks seems to take a while when holding down the controlls than I'd like.
Sound quality is great for the price and nothing sounds muddy if you have good quality music streaming through. Bass is very present with the proper seal. I recommend inserting the earbuds like you would foam ear plugs, pulling the ear back and inserting the headphone. (FYI: it gets a little tougher to get a good seal if there's some ear wax present of if you're sweating (keep'em clean and dry'em out!).
MOTORCYCLE STUFF: These fit great under a full face helmet if you aim the wire from the buds as straight down as possible. Of course if one gets loose, you'll need to finagle a finger to set the ear bud back in place (as with any earbud) With large buttons and light textures for the three buttons, the controls are very easy to distinguish with (summer) gloves on. Wouldn't try to answering a call while riding, there is no wind noise reduction to help out especially since the microphone is integrated with the controls (which will be on your neck out in the elements)
