Philips SHP9500 vs Sennheiser HD 560S

The SHP9500 is the headphone people keep pushing on anyone curious about hi-fi who does not want to spend real money, and the reason is specific: 32 ohms at 101 dB is easy enough that a phone or laptop output drives it properly, so the headphone is the whole purchase. That is not true of anything else in this guide.

Its character is a wide, open stage with sharp left-to-right placement, which is why it has a long tail as a competitive-gaming headphone and why detail-hunters use it to pull a mix apart. The 50mm drivers sit angled in a large, shallow cup, and the cloth pads breathe well enough that summer sessions do not get sticky.

The deviation from neutral is at the bottom. Sub-bass rolls off audibly below about 60 Hz, so kick drums land as a tap rather than a thump, and electronic music loses its floor. Treble sits forward enough that a poorly mastered recording can turn edgy. The cable detaches, which matters more than it sounds: the stock cable is long, thin and the part owners replace first.

The HD 560S is what the SHP9500 owner buys next. Sennheiser tuned it close to a diffuse-field reference rather than to a shop demo, so vocals sit where the engineer put them and a bad mix sounds bad. That is the point of it.

The practical argument is the drive spec. At 120 ohms and 110 dB it plays loudly and stays controlled from a phone dongle or a PC jack, which is unusual for a headphone tuned this honestly. A small amp tightens the bass and adds headroom, but the headphone is not waiting on one to be usable.

Bass extends flatter than the Philips does, but it is deliberately unexaggerated, so anyone coming from a consumer tuning will read it as thin for the first week. Treble is lifted slightly around the presence region, which reads as clarity on good recordings and as glare on harsh ones. The build is almost entirely plastic and the headband creaks when you adjust it, though the velour pads and the low clamp make it the most wearable of the three over a full workday.
