Sennheiser HD 400 Headphones Series Expanded At IFA 2015

Sennheiser has updated its HD 400 product lineup with new headphone models: the HD 451, HD 461, and HD 471. All three models isolate the listener from ambient noises, but retain a lightweight and closed-back design. Likewise, all three of the models are made with neodymium magnets; the two higher end headphones, the HD 461 and HD 471, offer superior sound quality, with the HD 461 being tailored toward the bass-lovers among us, while the HD 471 is more neutral and balanced.

Says Sennheiser, its HD 400 series of headphones are designed for on-the-go use (though, of course, you could use them anytime). As such, they have closed-back designs, which keeps the audio contained and will let you listen to audio in private. In addition, the ear cups have an over-the-ear design for both noise isolation and comfort.

These are not wireless models; they feature single-sided and tangle-free cables. The ear cups are made of leatherette (the HD 461 and HD 471 models only). Those two higher-end models also feature detachable cables with integrated inline remotes and mics for music control and taking calls. Models are available for both Android and iOS.

The HD 471 has the most features, and boasts a 3m cable, a plug that is gold plated, and a 6.3mm stereo adapter for use with an audio system. In addition, the highest-end model has its own carrying pouch.

The HD 451 model will not be launched in the US; pricing was not provided. The HD 461 and HD 471 will be available in the US, however, starting next month, with respective prices sitting at $89.95 and $109.95.
