I have owned various headsets - Plantronics 520, 925, Sennheiser, Jabra, Motorola, Jawbone etc. By far this is the best for the money. Currently only being sold at At&t - online and in-store. Original Jawbone noise canceling appears again in this unit, but the improvements are:
* Size. MUCH Smaller, lighter. * Fit. MUCH better than the original. 4 leather (?) covered ear loops - way more comfortable. * Ear buds. speaker can be seen through the ear bud - plus the comfort level WAY better. * Design. Sleek.
Unit stays in place; wore it all day - no issues, NEVER moved while wearing it- unlike the original. Comfortable to wear ALL DAY. I work in various conditions - driving, A/C on, radio,wind - by far Jawbone is the best , outperforming all other units. Worth the $$. Picked one up at a B&M At&t -fast and easy - but they sell out quickly.Get it if you can find it!!
