IMO, any super-high-end headphones are going to be a waste when used on a Treo.
The original poster asked about the possibility of active noise-cancelling headphones - The only ones I've seen in earbud form are the Philips HN060 earbuds. They get very mixed reviews, some people say they're excellent, some hate them. The reviews were just as mixed for my new Philips HN100 circumaural NCs, and I can say this without a doubt - In the sort of environments they were designed for, the HN100s ROCK.
Note that in quiet environments or ones where the noise is higher-pitched (such as office chatter, voices, etc.), headphones with good isolation (such as big circumaurals or the high-end earbuds) will work better than ANC. In environments with lots of low-pitched noise (Airplanes, automotive road noise, sitting on a riding lawnmower), ANC is the only way to go. In such environments, any ANC headphone will eat a non-ANC headphone for lunch, no matter how expensive the non-ANC unit is. The highest-end Etymotics or Shures will be useless when sitting 20 feet from a turbofan engine, or 2 feet from a barely muffled 11HP one-cylinder lawnmower engine. Even the cheapest ANCs will make a huge difference in such environments.
At the price they're available for these days, you can't go wrong with a pair of ANC headphones. Philips HN100s go for $15 on eBay these days, and the HN060s can be bought for $30 at Target now. Get a pair for airplanes/trains/passenger seats of cars/lawnmowers, and then buy your choice of "quiet environment" headphones too. Note: I haven't tried the 060 earbuds yet but want to, I have the circumaural 100s and love them.
As to what's available in 2.5mm native - Pretty much nothing. The market for 2.5mm stereo headphones is currently too small, as it only consists of dual-function phone/music player units.
