When it comes to features and extras, Phiaton doesn't make much of an effort with the PS 320. The earphones fold flat and in for compact storage, and there's a thick leatherette pouch with two compartments included in the package. Beyond that, there's not much to speak of, which is a bit of a disappointment considering all the accoutrements offered by the Phiaton PS 300 NC headphones. For $100 more, you get noise-canceling functionality, a bass boost option, a removable cable with an inline mute button, a hard-shelled carrying case, an airplane adapter, a quarter-inch adapter, and an innovative battery charger with multiple international adapters. By comparison, the PS 320 doesn't seem like that good of a value.
However, the PS 320 headphones do provide very clear and detailed audio playback, and overall sound quality is on par with what we expect from models in this price range. The one potential drawback for some listeners is that these earphones err on the side of bright, crisp sound reproduction, meaning the low-end doesn't provide enough oomph in certain cases. For example, Ice Cube's "Good Day" sounds relatively deficient, though bass is not entirely absent. As such, hip-hop fans may want to steer clear of these 'phones. Surprisingly, electronica such as Skeewiff's "Coming Home Baby" perform better, perhaps because the bass is less forward in that track. Still, we tend to think the PS 320s aren't the optimal option for dance music either. Classical music lovers, however, will be infinitely pleased with the tinkling clarity.
In the final analysis, the Phiaton PS 320 headphones aren't an everyman's (or everywoman's) model; rather, they're suitable for users who prefer a super crisp and bright audio response. They're also plenty comfy for extended wear, but we'd like to see a few more extras offered for the $199 price tag.
