The LG HBM-905 is a refinement of a previous LG Bluetooth headset, the. It has a similar design to its predecessor, but with updated features and slightly different controls. The long boom mic houses three microphones, which help the headset cancel out extraneous noise.
Long and skinny, the HBM-905 is a lot larger than the usual Bluetooth headset. Measuring 3.28 inches long by 0.63 inch wide by 0.4 inch thick, the HBM-905 starts out wide at the top and tapers down to a long boom mic that cradles the side of the face when worn. However, it is a touch smaller than its predecessor, and is now adorned with a faux wood finish and chrome details. Despite the style, we think some people might not like wearing such a large headset. On the front of the headset and near the top is an LED indicator that flashes white when the headset is powered up. Beneath that, the entire front piece can be pressed down to act as the multifunction call button. We much prefer this physical control over the touch-sensitive button of its predecessor. There is no real volume rocker, but there is a single volume button on the right side that you can press a few times to cycle through the different levels. The Micro-USB charging jack is on the left, while the power switch is on the back.
Also on the back is the earpiece, which is clad in a slightly oval rubberized earbud cover. It no longer plugs up the ear as the previous model did, and sits gently outside the ear canal. It's quite comfortable, but you do still need the optional flexible ear hook to wear the headset securely. However, it's just as flimsy as before, and we're afraid to do much adjusting in case it breaks.
