Our Verdict
Philips SHP9500
Superlux HD 681
The Philips SHP9500 are somewhat better for neutral sound than the Superlux HD 681. The Philips are more comfortable, more breathable open-back headphones with a considerably better build. Sound is perceived as much more open and spacious as well. They share a similar sound profile that features balanced and articulate mids at the expense of bass extension and an overly-bright treble range.
