The drawbacks to our HeadRoom ears are it's a rather ruthless, unforgiving presentation not well-suited for compressed digital recordings since the SRH1840 tone is penetratingly precise and even slightly prickly at times. But feed the SRH1840 from an LP turntable source + headphone amp and you'll hear vast definition and a clear, unblunted musical space that sounds excellent with most genres and styles. Bass response is audibly fuller and better extended than the lower-tier Shure SRH1440 edition but still remains extremely controlled without much sub-stratic mass, so hip-hop, reggae and electronic music people may wish to add low-end EQ depending on tastes. For producers and audio professionals performing final soundtrack or mastering edits, the Shure SRH1840's faithfulness comes as a revelation of fresh insight into your work. Low sensitivity specs favors using the Shure SRH1840 with headphone amps for maximized acoustic definition, improved dynamics and clearest possible transparency.
The Shure SRH1840 headphone comes in a modern metal-flake grey/black color and has a totally open-back circumaural ['around the ear'] earcup construction that will completely cover the earlobes on most wearers. As with all open-back cans, the design provides no isolation or noise-blocking ability and will also 'leak' audio out of the headphones as well, so the SRH1840 are not recommended in situations where listening privacy is needed or for close-mic recording work wher you may be trying to avoid mic bleed. Two detachable headphone cords allow easy replacement if ever needed, a great thing to extend product lifespan and durability. The quality OFC headphone cabling attaches in a 'Y-type' design with discrete 'snap-in' connections into the left / right earcups. A extra cable is provided in the SRH1840 box along with an extra set of earpad cushions -- a nice plus from Shure.
