Sennheiser HD 650

ComfortIsolation
Open-backed design gives a nice audio quality. Doesn’t isolate well and leaks like crazy.
Isolation (1.26)
We have found, through scientifically rigorous testing, that open-backed headphones don’t isolate well. This may be shocking news to some, but we assure you it’s correct.
Since the HD 650s don’t have any physical barrier blocking out external noise, and they don’t have any active cancellation wizardry going on, they have very poor isolation.

Leakage (2.90)
Again, since these are open-backed headphones, there isn’t much of a barrier between your soundstage and the world around you. The HD 650s leak like crazy, thus fulfilling the purpose of their design.

Maximum Usable Volume (6.51)
The HD 650s were capable of outputting 105.33dB without accruing significant distortion. Given that these headphones have open backs, this is actually pretty impressive and should allow you to annoy everyone in the vicinity with your music.
We award maximum points for 120dB, which is the loudest you’d want your playback unless you’re determined to deafen yourself. Since the HD 650s are open-backed headphones meant to be used in a private listening environment, 105dB should be plenty loud.

The Sennheiser CX 680i in-ear headphones are a decent set of lower-mid-range headphones with a remote & mic.
