I've always been a big fan of Sennheiser's HD-25 line, I've used a pair of the HD 25-1 II for a while now, and they've done well for me except for a few design issues. The cable not being coiled was always problematic, and since it was hardwired into the unit, there wasn't much I was going to do about it.
Recently I was sent a pair of the HD-25 Plus to take on a road test, and to my delight, they have added everything that I was missing. You now get an extra set of velour style ear pads and swappable cables that come in both straight and coiled.
The velour ear pads are quite comfortable and do make a big difference, but my true delight is the coiled cable which has been a game changer for me personally and after about 10 gigs rocking these my old HD-25s have been moved to the home studio permanently.
The line has also been refined, or maybe I should say simplified, into three models now. Before I kind of lost track, there were just all sorts of skews that weren't that easy to identify. So bravo, things are easier for the consumer now.
The New "Simpler" HD-25 Range:
The HD 25 LIGHT is a less expensive single band unit, a bit like the HD 25-SP II.
The HD 25 is the classic model - great, but you might as well get the plus.
The HD 25 PLUS (This is the one to get, worth every extra dollar) Comes with two cables (one coiled), a bag, and spare velour ear pads.
The official statement below. In case you want even more clarification.
Audio specialist Sennheiser has streamlined its classic HD 25 pro headphones portfolio to make product selection easier. “With seven variants to choose from, customers often asked ‘But which one is the HD 25?’,” said Jannik Schentek, portfolio manager Live Performance & Music. From March, there will be one classic HD 25 with two sister models – the HD 25 LIGHT, with has slightly different features and accessories, and the HD 25 PLUS, which adds additional accessories to further enhance the classic. The new versions can be easily recognised by the compact Sennheiser logo on the earpieces, with the version and impedance information now provided on the headband.
The classic HD 25 comes with its iconical split headband, 1.5m single-sided connection cable and a flip-away earcup for single-sided listening. Newly designed headband ends ensure that the earcups lock securely into place, while lightweight aluminium voice coils ensure an excellent transient response. With a frequency response of 16 to 22,000Hz, an impedance of 70 ohms and a maximum SPL of 120dB, the HD 25 lends itself to any monitoring task, whether broadcasting, live recording or in the DJ booth. The HD 25 comes complete with a screw-on jack adaptor to 1/4” inch (6.3mm) for its straight steel cable.
Its sister model, the HD 25 LIGHT, is the entry-level version for demanding consumers and cost-sensitive pro users who are looking for a good pair of mixing and monitoring headphones. The HD 25 LIGHT features a simpler headband design and slightly different drivers but brings a well-defined bass and detailed treble to any monitoring task. The headphones have an impedance of 60 ohms, a maximum SPL of 114dB and a frequency response of 30 to 16,000Hz. The straight, dual-sided steel cable (3m) comes complete with a 3.5 to 6.3mm (1/8” to 1/4”) adaptor.
The HD 25 PLUS is identical in design to the HD 25 but spoils its users with extra accessories and two included cables. Users can choose between a coiled steel cable (length: 3m/1m) and a straight, 1.5m steel cable. The PLUS version also comes with a handy storage pouch and a second set of ear pads in a soft velour version.
“The HD 25 is a true classic that enjoys an excellent reputation in fields as diverse as outside broadcasting and DJ-ing,” said Jannik Schentek. “The new portfolio is now more clearly defined with each model clearly differentiated, and ensures that both pro users and consumers will get just the right pair of headphones for their preferred applications.”
