Not sure how many of you will be interested in this but I thought it was worth a mention. Two weeks ago I reviewed the Aliph Jawbone II Bluetooth headset and docked its rating for having a lousy ear hoop connecting it to your ear. This made it fall off easily and lose connection with your jawbone causing it to cancel out your voice as background noise. This was a shame since the original Jawbone had a great ear hoop and is still my headset of choice.
Ivan let me know in the comments that he found a great but pricey solution for fixing this issue. AverySound sells custom molded earpieces for the Jawbone and Jawbone II that completely eliminate the need for the Jawbones ear hoop. The earpiece holds your headset to your ear by using a custom mold of your inner ear. This makes a perfect seal of your ear allowing you to lower the volume since it blocks out background noises.
The earpiece is pricey at $69 per earpiece especially on top of the cost of a Jawbone but it makes sense once you understand the work they put into it. Once they receive your order you will be sent an impression kit that lets you make an impression of your ear. You then mail them back the impression using their prepaid mailing box and they will send you back a custom made earpiece that they guarantee. A friend of mine had something similar done for his headphones a bit back and he cannot stop raving about it.
You can order the Jawbone II earpiece at this link or a earpiece for the original Jawbone at this link. I am going to try and pick one up and do a review. Let me know if you get one! I can definitely see this being useful for people who are constantly on their Bluetooth headset.
