An open design leaks the room in and the music out, which is why it belongs in a quiet studio and nowhere else. This pair solves the problem the other way, with sealed earcups and a topology diaphragm inside.\u003c\/p\u003e\n\u003cp\u003eThe specification is unusually honest about what it is. The vocalism principle is dynamic, there are two drivers, and the frequency response runs from 15 Hz to 35,000 Hz, which is the sort of extended upper range that usually costs a serious amount more. Impedance sits inside a 33 to 100 ohm band with the rated figure at 60 ohms and a sensitivity of 100 decibels, so a portable player will drive it without a separate amplifier, and a desktop amp will not overpower it. The material is ABS, the cable runs 1.5 metres, and the plug is an L-bend at 3.5 millimetres, which is the shape that survives a phone in a pocket.\u003c\/p\u003e\n\u003cp\u003eThere is no active noise cancellation and no control buttons on the cups, which some buyers will read as a missing feature and others as the point. ANC circuitry adds a noise floor and a battery to a wired headphone, and buttons add a circuit between the driver and the ear. What is left is a sealed, wired, over-ear design at 60 ohms that asks nothing of a battery and gives nothing to the room.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eOne listener, one signal path, nothing in between.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\u003chr style=\"margin: 20px 0;

Podcast editors working through a two hour interview prefer a passive headphone without ANC circuitry for the same reason a photographer prefers a mechanical shutter: one less thing adding to the signal. Buyers running a budget desktop amplifier get a 60 ohm load that sits in the easy range for almost any amp, and the 100 dB sensitivity means a phone or a laptop drives it directly without an external device. The extended frequency response to 35,000 Hz appeals to listeners working with high resolution files, where the upper harmonics are present in the recording but lost in playback. Travellers who dislike charging a battery before a flight will find the wired design a feature rather than a limitation, and the 1.5 metre cable with an L-bend plug is sized for a laptop on a tray table.\u003c\/p\u003e\n\u003c\/div\u003e\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #eee;\"\u003e\u003cdiv class=\"product-promise\" style=\"background: #fafafa; padding: 18px 20px; border-left: 3px solid #1a1a2e;\"\u003e\n\u003ch3 style=\"margin-top: 0;\"\u003eThe EastSupplier Promise\u003c\/h3\u003e\n\u003cp\u003eEvery unit is inspected before it leaves the warehouse.
