Let the hive mind of Engadget get that for you.
"I own an iPhone 3G and I'm looking for a decent speaker / alarm clock for it. I am going to listen music in a mid-sized room, so I want nice quality speakers with solid bass. I also want to use it as an alarm clock, so it would be great if there is such a feature. The price can be low-mid to mid-high range. I was looking at the Klipsch iGroove SXT; it's powerful, slick and the reviews are good, but it doesn't have an alarm clock feature. It's no deal breaker if I can set it up from the iPhone, but I'm not sure. Thanks!"
I bought the entire Jawbone w/ charger for about $100 on eBay. Just the earpiece itself from Jawbone was over $100. I thought I got a bargain but I really got ripped off and hence, I will NEVER buy Jawbone again and my own company will NOT pay for any Jawbone device!
Frankly, I didn't like the feel and it was very hard to put on and keep on when moving at all. The wind noise factor was also an issue. You must also keep the earpiece close to your face to work properly, which I see as a flaw. To have to pay over $140 for Jawbone, I will stay with my Motorola!!!
I would recommend a NO BUY on Jawbone, unless you like experimenting. But, there will be reasons you will eventually not like Jawbone and all the cognitive consonance in the world will not make it comfortable!!! And, you won't like their "customer service!" Actually quite arrogant!
