The Pioneer DJ HDJ-S7 is an on-ear headphone that’s more compact compared to the full-size HDJ-X series. The design is slimmer, lighter and feels less obtrusive when you’ve got it hanging around your neck. That comfort comes at a cost though: while the sound is rich and the bass plentiful, it lacks the power of the flagship HDJ-X10 because this has smaller speaker drivers and ear cup pads. The noise isolation also isn’t as good because the cups sit on your ears, as opposed to completely enveloping them. They are an improvement over its predecessor the HDJ-C70, though, and if you prefer smaller cans these should be on your shortlist.
