The Jabra BT150 updated design uses a rubber ear hook instead of a plastic one that is far more comfortable. No color plates like the BT130; the BT150 headset is solid black, save for its chrome action button on its side and volume controls (on the bottom when the headset is worn on the right ear). The action button also houses a multicolor LED that is blue under most circumstances and flashes red when low on power, which is a nice touch.
The Jabra BT150 uses the same kind of power connector as the Jabra JX10, though it doesn't come with a charging stand or USB cable like the JX10. Then again, the BT150 is also almost a third of the price of the JX10. The power adapter is designed to work well in a power strip and doesn't overtake other plugs.
To pair the Jabra BT150, make sure it is on and then hold in the action button and the volume up button until the LED is solid blue. Passcode is 0000.
Just like the BT130, you have to hold the action button for about 10 seconds to turn the Jabra BT150 on and off. That's way too long, especially compared to the JX10 which only requires you press the button for a second to power on and about 5 seconds to power off.
Once you finally power on the Jabra BT150, with a blue LED flashing every three seconds while in standby mode.
The Jabra BT150 quickly auto connects when making and receiving calls. When I used the headset with a Treo 650, I had to keep the Treo nearby otherwise both sides of the call would hear static. I couldn't even keep the Treo in my pocket without hearing some static. When I was outside, the other caller complained that traffic noise made it difficult to hear me.
On the other hand, the Jabra BT150 worked very well with a Sony Ericsson K750. I could keep the K750 in my pocket and not hear any static at all, while outside surrounding noises didn't drown me out.
When wearing the Jabra BT150, the headset feels loose; it stays on but doesn't pass the shake-your-head-violently test and bends away from the face when leaning over. The ear hook is far more comfortable than the one that comes with the BT130 and doesn't cut your ear like the older model. You can switch ears very easily, and I like how light the BT150 is.
