I don't know about you, but I don't especially care what my headphones look like—I can't see them while I'm wearing them, and I'm not counting on headphones to enhance my admittedly low social status. But I do want them to sound good, and in this area the 325is 'phones excel, providing excellent overall sound, with a neutral to cool character. Like the SR80i model, these headphones are fairly open sounding, with good dynamics. Bass has good impact, is well defined, and goes fairly deep, and midrange is very clean and has exceptional detail. Treble is similarly detailed and extended. Compared to the SR80i, the SR325is has sound that is more detailed and dimensional. In short, it sounded good enough that many listeners will find it to be the benchmark for sound in this price range.
While the 325is has high sensitivity—meaning the headphones can be used with all but the lowest-powered portable devices—the headphones are fairly large, which could matter if you want an easily portable model. Also, they have an open-air design, so they don't block out external noise the way many in-ear and over-ear models do. And a decent amount of sound can escape from the earcups, which might be a concern if you don't want to bother others while you get your groove on. As such, they're probably best suited for use in quieter environments, or in situations where you might want to be able to hear what's going on around you while wearing the headphones.
The Prestige 325is model is still widely available, but the company just introduced a new Prestige "e" series that will replace all the "i" and "is" models, including the SR60, SR80, SR125, SR225, and SR325. We hope to get some of these newer headphones into our labs for testing soon, so keep checking our headphones Ratings for all the latest updates.
