An on/off switch, play/pause button, speaker/earbud switch, forward/back buttons and a very nice volume roller which has a nice click to it rather than just a smooth roll.

Like, really really crappy volume with earbuds and no bass at all with the external speakers.

neat idea, poor volume.

There is an added switch to select between earbuds and speakers; the convenient volume and previous/next sliding toggles of the 900 and 910 have been replaced by prev/next buttons and a push scroll wheel for volume and tone control

neat idea, poor volume.

Sound volume not good, have to be in silent area to hear well

I also feel like the volume doesn't go high enough sometimes, especially in speaker mode

Surround sound was good and the volume level appropriate

According to all of LG's hype about the Tone Studio, this was groundbreaking new technology that gave the listener "rich volume and theater-quality sound", "real 3D Surround" and the promise that, "the Wearable Bass speakers allow your body to feel the sound as if you are right there"
