After my rather disastrous and mostly disappointingly purchase of a Motorola MOTOROKR S9 Bluetooth Headset, I felt a bit stung as well as buyers regret. But not quite enough, apparently, and despite the somewhat lukewarm reviews of the Motorola S805 "DJ" Headphones.SOUND: GOODFairly crisp and clean and strong enough to be head on a busy city street. Reproduces bass levels nicely and does a fairly good job at shutting out external noise (these are not noise canceling headphones by nay means, but the fact that they fully enclose the ear creates a fairly decent seal).And like the MOTOROCKR S9, loud enough to hurt at the highest level.CONNECTION: DECENTAnd now the bad news. Once the device is actually connected, it holds it quite well. I can have my phone in my pocket, or my MacBook in my bag, and not loose the signal once. I can even leave my Samsung Blackjack on my desk, walk a few steps down the hall to the kitchen, and not have the sound drop out. Very nice.Unfortunately, consistency at startup seems to be the issue here. Once I have paired the headphones to both devices, I seem to constantly need to reconnect them every time I turn the headphones on. And since that only seems to work half of the time, I need to erase the Bluetooth profile and reconnect it as a new device. I would have suspected my devices were causing issue were it not for the fact that the MOTOROCKR S9 had no issue connecting and reconnecting.Theses headphones do appear to be better shielded the the MOTOROCKR S9; I did nit notice any of the sound dropout when I passed other strong radio signals.EASE OF USE: GOODIgnoring the hugely annoying issue of keeping the headphones paired with your devices, once connected the controls on the device are simple and intuitive. You have controls for volume up/down and track forward/reverse as slide rings around each ear that are chunky and rubbery enough to provide flawless control. Oversized buttons over each ear also allow the user to play/pause a song, answer/disconnect calls and use voice activation (assuming the device they are connected to have voice activation, which my Samsung Blackjack does not)COMFORT: GOODAside from the unfortunate decision to make the headphone bar slightly narrow and pyramid shaped instead of a smooth rounded edge, resulting in a pinching for those of use with larger craniums, these are very comfortable headphones that I can wear for a few hours without discomfort. They are fully adjustable, and should fit just about anyone.CALLS: DECENTAgain, nothing spectacular here. Like most headphones, the headset part of this device was a secondary thing, and while calls coming is sound rather good, you will not. Only appropriate for quick conversations.BATTERY: GOODI am getting about 6-7 hours of battery life off each charge, which takes a little over 2 hours. And it can be juiced with a standard mini-USB plug. Nice.RECOMMENDED: YES
