Pros: Stylish design, lightweight, compact, good sound, blocks outside noise.
Cons: Somewhat bright sounding high end.
Summary: I cannot collaborate reports of lacking bass; they have quite powerful bass output. If experiencing weak bass, I suggest trying the different silicone ear pads for best fit.After owning this product a while, I've concluded that, as the editorial review suggested, an adjustable head band would be an improvement, one that should be incorporated in future versions.
The treble is slightly aggressive and harsh, which may be a benefit for those with hearing loss. But the powerful bass helps Balance things out, and provides an overall pleasing sound quality. Vocals and sonic details are clear.
These are efficient headphones. I believe the rated 100 dB sensitivity is conservative. The Sony MDR-AS50G are much louder than my Philips SHN5500 noise canceling headphones (also rated 100 dB) with the power off, and slightly louder still with the Philips powered on. I'd rate them at least 110 dB. And the silicone ear pads provide good acoustic isolation, comparable to my noise canceling Philips, an added bonus.

Since they did not include an adjustable head band, and the fit was slightly loose, I pulled out my tool box and went to work. Attaching a two inch wire, cut from a clothes hanger, to the center point of the headband allows a more secure fit and consistent sound by bending the metal attachment to a smaller radius than the headband's. The physical connection is a challenge. I clamped the parts and coated in Goop household glue, then tightly wrapped in 3M electrical tape when dry. Sure, a hassle, but the end results are worth it.
