The cord with the clip seems to be positioned in not quite the right place, it pulls down on the headset a little. Its not that big of a deal. I prefer the wired headset over bluetooth as the bluetooth quality of sound deteriorates too quickly. So far this headset is very reliable. The carry case allows me to fold it up and keep it in my purse. It Doesn't Fit In The Case (Without Bending It) Rating: 4 I started using this headset two days ago. Sound is good. You can speak at a normal volume level and you will be heard. I don't use it outside though. The earplug does give you a sense of being underwater, the way it blocks your whole ear canal. But that's how it blocks out noise. I do think for the money there should be some sort of volume/mute control on the cable. But, I knew there wasn't when I bought it. My only complaint is that it comes with a case, yet the headset doesn't fit in it without bending the microphone stalk and I'm not comfortable doing that. It's sensitive equipment, with a filter in the earpiece that I know I'll have to change eventually hence the included tool for same, then it shouldn't be left in the open to collect dust. Why not give a case that accomodates it and its accessories? Best earbud I have owned. Rating: 5 I have used wired and wireless earbuds. Most of the units I have used have been inadequate in overcoming road noise and providing clarity. The Etymotic ER22C fits snugly in your ear canal. Be sure to try the different molded earplug inserts supplied. I started using it with the one installed by the manufacturer and then tried another only to find the second gave me more volume and clarity. Unit is supplied with 2.5mm plug and I had to find adapter for my Blackberry Curve. You won't be disappointed.
