I bought the Bose Triports as a longtime Bose fan, I had read about the headband failure, and figured out if you bend the headband wider (grabbing only the cloth covered portion at top while doing so) then you will relieve the stress on the headband and avoid the headband problem.
 
The bang for buck for the Triports is quite poor, If any of you have purchased some Koss Portapros, and when you first held them said "I paid $50 for these!?" Same thing here except they kill themselves if you do not widen the headband as described in the intro, cost three times as much, and for the money don't sound as good as the PP's that and the PP's have a lifetime warranty. If the Triports had cost $70 and didn't kill themselves, I would've given them 4-5 stars.
Since I consider these headphones "suicidal" I give them the moniker "EMOPHONES"
 
Tested on a Sony Walkman S639 W/A PA2V2 Amp
IMO, AQ is #1 (provided the phones don't kill themselves) when purchasing a set of phones.
Bass; The bass is adequate, but lacks definition, and comes off as "boomy" on curtain tracks, I would just stop short of calling it "monotone". There is NO tightness, and very little control to the bass on the Triports, they're all over the place.
Mids; The upper mids (female vocals) are present, not recessed or anything, Male vocals are slightly recessed, they are muddied in the lower end but not severely. They are also slightly veiled.  They have a slight warmth to them, but that might be the PA2V2.
Highs; The highs are slightly exaggerated, not as exaggerated as Sony's (generally) but they are a little more pronounced then they should be. The highs have a little more detail to them than the mids or the bass. I would go as far as to say they are on the bright side. The highs are actually acceptable on the Triports IMO.
Soundstage; The sound stage has very little depth, so it stays "in your head" but it has a little width to it, but most $50-$30 earbuds will whip them in the soundstage dept. Overall the sound stage is "canned" sounding until you wear them for a few minutes, A Cowon player with SRS might remedy this.
Dynamics; They don't have quite the punch I was expecting from them, but running through my mind, I don't think ANY Bose product I've owned has ever been very dynamic, They do have some punch, but my sub $100 buds are more dynamic.
The Triports are famous for their failure rate, but other then the self-terminating headband, the fit and finish is quite nice, they have a good silver finish, no paint bubbles, no cast marks of remark, no rough edges, they are decently polished. When you look inside the earcups you can see unpainted gray plastic I felt this should have been covered with felt or some other covering considering the price. They feel light and cheap considering the price, for what Triports cost you can pick up some Pioneer SE-A1000's and they are ten times the cans, and have the bass you were expecting the Triports to have.  A word of warning, take care of the pleather earpads, they will deteriorate over time if you don't (I use STP "Son of a Gun!") and Bose charges a considerable amount for new ones.
 
Comfort is one area where the Triports excel, due to the fact they are so light, the headband (once bent as described in the intro) doesn't cause any discomfort (IME) during any prolonged use. The earcups can get hot and sweaty if you are in a warm environment or working out. My ears are on the larger side so I sort of have to shoehorn them in, but once on they are pretty comfortable, nothing bad here.
 
Due to the fact they kill themselves, I would avoid ANY physical activity while using them. I would suggest a Computer/ home only role, even when you have bent the headband. They just scare me, so I baby them, and one shouldn't be afraid of using their headphones.
 
Overall, I wouldn't buy them again, the $130 would have better been spent on M50's or a pair of Sennheisers. If these were $70 and they didn't have the headband problem's as I said above, they would be worth it, but for the price, considering they break, I'd stay away unless you can get them cheap, REAL cheap, and bend the headband before any white stress marks appear on the band.
