Sennheiser took the wraps off a handful of new headphones during IFA 2016 in Berlin. The company introduced two new lineups dubbed the HD 4 and HD 2, and in addition, Sennheiser brought new updates to the ongoing HD 500 series of on-ear headphones, with the addition of the HD 559, HD 569, HD 579 and HD 599.
Starting off with the Sennheiser HD 4 series, it includes two headphone models, namely the HD 4.20S and HD 4.30. They both have an over-ear folding design with noise cancelling, and they both offer in-line remote controls. However, while the Sennheiser HD 4.20S is equipped with a 1-button smart remote on the cable, the Sennheiser HD 4.30 features a 3-button remote. According to the manufacturer’s website, the Sennheiser HD 4.20S headphones have an 18 ohm impedance, a frequency response of 18Hz-20,000Hz, and <0.5% (1kHz/100dB) total harmonic distortion. Unfortunately, these technical details are missing from the HD 4.30’s description, which only makes mention of compatibility with iOS and Android devices including the Samsung Galaxy series, LG, Sony, HTC smartphones and more. Moving on to the second series of headphones meant to replace the Sennheiser PX 100, 200, and HD 200 lineups, the Sennheiser HD 2 consists of three headphone models, specifically the HD 2.10, HD 2.20S and HD 2.30. Once again, the Sennheiser HD 2 adopts an over-year folding design and two models – save for the HD 2.10 – have in-line remote controls featuring 1 and 3 buttons respectively, as well as a microphone. The spec sheet for the Sennheiser HD 2.20S mentions a frequency response of 18Hz-18,000Hz, 26 ohm impedance, and <0.5% (1kHz/100dB) total harmonic distortion.
As for the HD 500, Sennheiser has announced a range of updated over-ear headphones dubbed the HD 559, HD 569, HD 579 and HD 599. All the other models have replaceable pads and large earcups, and with the exception of the Sennheiser HD 569, they all have an open-back design, which means that they are generally meant for home entertainment. Sennheiser confirmed that all the new headphones will begin hitting the shelves by the end of the month; however, as yet pricing details are missing. Nevertheless, we expect the Sennheiser HD 2 lineup to have a lower price tag than the HD 4, and the Sennheiser HD 4 to fit somewhere in-between the HD 2 and HD 500 series.
