Ordered this BT to replace the Plantronics Voyager 510 and have not been disappointed.  Unlike other reviewers I have not had any issues with the fit or ease of placing the headset on my ear.  The ear loop is very comfortable and I can wear it all day and forget its there even when I am wearing my glasses.  My boyfriend ordered one as well and he did have to use the Jabra eargels to achieve a good ear fit for him, but after inserting the Jabra eargels has had no issues with headset at all.  Headset was pricey, however found a good deal on Amazon and paid about $20-$25 less than I expected to on the web and at least $40-$60 less than I would have paid in Best Buy.
