Three of the new models — the HD 559, HD 579, and HD 599 — are open-back designs, which offer a more expansive sound stage but aren’t great for wearing around the office. For those who would rather keep their tunes to themselves, the HD 569 is a closed-back design. The HD 4 and HD 2 series are meant more for those on the go, with Sennheiser head of portfolio management Ivan Kuan calling them “everyday audio heroes that can considerably enhance your mobile listening experience.”
The HD 559 and HD 569 are aimed at those who care about sound quality, but don’t want to spend too much money. In the case of the HD 569, it’s also meant more for mobile users than the rest of the line, being the only model to include an optional second cable that includes an inline mic and remote for use with a smartphone. Both the HD 579 and HD 599 offer even better performance, with the HD 599 being the top of the range.
The HD 4 series is comprised of the HD 4.20s HD 4.30i, and HD 4.30G, all of which are around-ear, closed-back designs that offer what Sennheiser calls “bass-driven sound.” All three models come with flat cables featuring an inline mic and remote, with the HD 4.20s using a single button remote and the HD 4.30i and 4.30G adding volume controls for iOS and Android, respectively. The latter two models also come with included carrying pouches.
The more affordable HD 2 series functions as the successor to Sennheiser’s PX 100, PX 200, and HD 200 series, and is comprised of the HD 2.10, HD 2.20s and HD 2.30i and HD 2.30G, all of which are on-ear designs. While the HD 2.10 is the most barebones, the HD 2.20s adds a single button remote and inline mic. Like the HD 4 series, the HD 2.30i and HD 2.30G add volume controls for iOS and Android, as denoted by the i and G in the names. Both also come with carrying pouches.
“Designed to offer great convenience and portability, the HD 2 headphones fit effortlessly into your everyday life, allowing you to enjoy music on the move without hassle or bulky storage,” Kuan said in a statement. “They are designed to be so lightweight and comfortable, you can nearly forget you are wearing them.”
All of the new models will be available for purchase starting in September. For more information, see the Sennheiser website.
