Summary: The Denon AH-D400 bass headphones do produce bass like other best bass headphones, but in exchange they compromise precise sound quality. They fit snuggly on your head, keeping them in place without wobbling, but also tend to clamp more than secure. The AH-D400s bass reproduction is far superior to bass headphones with in-ear designs but can't quite compete with other over-ear bass headphone models.
Pros: Crisp highs boost vocal sound quality and low impedance keeps the battery full on your music devices.
Cons: The bass is disappointing. Even though there's plenty of it, it's not good bass.
Summary: The $239 Denon Urban Raver headset is definitely for those who like a bassy kick and a flashy design. The midtones are faded on the edges, but the overall listening experience really pops. And, unlike the SMS Audio Sync by 50 Wireless headphones ($243.99), the low end isn't overpowering because the Ravers up the bass in proportion to the rest of the levels. We just wish the knobs on the sides of these headphones didn't stick out so far.
Pros: Amplified mode makes music more clear, Comfortable memory foam earpieces, Cool app for tweaking settings and Internet radio
Cons: Knobs on the earpiece are too big, Midtones fade along the edges
