Bose's In-Ear Headphones, aka the "TriPorts," may not earn a plaque in the consumer audio product Hall of Fame right nextHeartbeats headphones (http://www.goodej2010.com) to the Quiet Comfort 3—without a doubt the best noise-canceling headphones on the market. Even so, the amount of low end these earphones produce is admirable, given their cost.The TriPorts have had an interesting history. After their initial launch a few months back, customers complained about insecure fit, to the point where Bose actually had to redesign the product and relaunch it. It would seem Bose earphones headphones (http://www.goodej2010.com)that the company has resolved these ergonomic issues, as my TriPorts are firmly in place as I type. But something is still missing here: treble. Although these earphones pump out plenty of low end, that should be balanced by high frequencies—which aren't there. You might not notice this at first, but if you compare them with a comparably priced pair of headphones from Shure or Ultimate Ears, you'll hear all the crispness you were missing.
