  • The most important 2012 headphone release for AKG Acoustics is the K550 sealed audiophile model. The K550 is a full-size closed-back design efficient enough to be driven from portables like iPads or laptop computers while delivering the accuracy of the famous AKG K701 (semi) open-back reference headphones, but with an audibly fuller bass presence. Finally, here's a well-priced circumaural 'closed' headphone that rivals the top cans in the category in sound quality and is also built to withstand the rigors of serious portable use. To be honest, we were planning to quickly check the K550 for a fast audio impression and then put them away for an expected long 'burn-in' process due to the typically laggard bass and edgy highs that top AKG headphones are renown for prior to burn-in. But even right out of the box, we liked the smoothness and detail of the midranges all the way into the upper high frequencies. But after 300 hrs of burn-in play-time, the K550 developed a fullness and heft of tone not initially heard. With certain audiophile recordings we did detect evidence of timbral sharpness or excessive grain at times, but it was fairly innocuous and not a deal-breaker for most of our testers. The K550 top-end forwardness is supported by a deep, balanced bass that sounds better-textured than any other AKG headphone we've heard. Indeed, the bass presentation sounds as typically tight as the K701 but with a welcome low-end texture perhaps only lacking extreme sub-bass extension. The AKG K550 mid-ranges stay focused and centered, and while the highs sing very crisply and articulate, they never hit the point of harshness even at loud listening levels. We found the soundstage imaging of the K550 also excellent with very well-delineated separation and simple definition, easily surpassing the spatial dimensionality of any other closed-back AKG headphone.

    The AKG K550 really feels exceedingly well built and durable with quite solid earcup-to-headband connections -- which are often the weak point of other closed-back headphones. Mobile or portable listeners should have no worries toting these around campus, taking them on airline flights or commuting from home to office. The K550 wearing comfort is also exceptional and the only quibble we had with the fit is it merely takes a bump of the earcup to break the flush 'seal' of the earpads against the earlobes. Fortunately, it's a quick thing to correctly re-adjust the fit and bring the proper bass response back to full fruition. We find the AKG K550 aesthetics appealing with an elemental but modern design and cool matte-black finish. As another minor quibble, we'd like to see a detachable cord in a top-level headphone at this price. The K550 will serve well in many varied applications and is a great upgrade in the studio or in the club for DJs and recordists seeking superior musical detail and tonal clarity. Audiophile listeners at home, office or on the move will delight hearing your old music made new again through the K550. Excitement is amazingly high for the AKG K550 amongst our jaded HeadRoom headphone freak all of us feel it is a great candidate for any listener seeking a tonally accurate sealed headphone with a tight bass response and accurate musical precision throughout all frequency ranges. So we think we have another massive winner from AKG Acoustics!
