This product is absolutely wonderful. The sound quality is great. especially with the noise reduction. It looks much better than most of the earphones available and I actually prefer it more than the newer versions which only come in gold, silver and black. The only reason I give it 4 stars is because of the design of the rubber cap. Everyone I know who owns this lost the rubber cap within 2 days. I haven't lost mine, but that's because I have it in a small compartment in my purse. I don't even bother putting it on because it won't stay on with regular use. Besides that, everything is wonderful about this jawbone.
