The GoodThe Bose TriPort In-Ear headphones have strong bass and good overall detail, and they're not intrusive in your ear canal.
The BadThe Bose TriPort In-Ear headphones don't block out any noise, and the fit doesn't feel quite as secure as advertised. The silicone tips come off very easily, and pick up tons of dirt.
The Bottom LineThe Bose In-Ear Headphones are a hybrid set, falling right between regular earbuds and canalphones. They don't block out noise, but they do provide much more bass than stock earbuds--almost too much, in fact.
The sweatproof $99 iSport Immersion earphones offer a very secure fit and impressive sound....
If you're looking for noise-isolating earbuds, the Bose TriPort In-Ear Headphones ($99) are not for you. Although they have silicone tips that protrude slightly into your ear canal, they are not meant to protect your ears from screaming children on airplanes--nor from the drone of the engine. They provide far better bass than your MP3 player's stock headphones, but the overall sound isn't a match for similarly priced in-ear 'phones. If you have a tough time sticking things deep into your ear canal or are paranoid about walking around without hearing much of what's going on around you, these are worth a listen, despite some physical design flaws.
The Bose TriPort In-Ear Headphones have an unusual if not unique design. They resemble the earbuds that come with the Samsung Yepp YP-K5; they look like regular earbuds but with silicone tips that funnel the sound directly into your ear canals. The symmetrical cables have an antitangle slider and terminate in a 3.55mm gold-plated straight plug. The plastic plug housing is oddly bulky and rectangular--seemingly just so the company could fit its logo on it.
You'll want to keep the Bose TriPort In-Ear Headphones' included case on hand to avoid cable tangles and keep the eartips clean.
