LATEST ADDITIONS

A classic in the world of professional and enthusiast headphones, and probably the world's most popular DJ headphone, the HD 25 has remained in the Sennheiser line-up in a small variety of incarnations since 1987 ... and deservedly so.

When I first heard them about 15 years ago there were very few expensive headphones available, so they seemed pricy at the time. They sounded great though and were a solid recommendation. In today's world of high-priced fashion headphones, and even higher priced high-end headphones, these very good sounding and highly functional cans seem like a real bargain for professional and audio enthusiast alike.

Let's take a look at the latest incarnation, the Sennheiser/adidas HD 25 Original.

It pours from your loudspeakers and into the room.

First up is Winging It: Piano Music of John Corigliano. Performed by Ursula Oppens, who has achieved legendary status as a new music virtuoso, the CD includes the world premiere recording of Winging It (2008), which the Pulitzer Prize-winning Corigliano wrote for Oppens.

Even newer are Capricho Latino, a disc from violinist Rachel Barton Pine of rare Spanish and Latin American music written solely for the unaccompanied violin; and The Pulitzer Project, performed by the Grant Park Orchestra and Chorus under Carlos Kalmar and Chorus Director Christopher Bell. Pine's disc includes Alan Ridout's Ferdinand the Bull with narrator Héctor Elizondo, and 13 other works by composers familiar and obscure. You can sample a few of the tracks before purchasing.

Instead, most speakers work this way: Complicated electronics split the audio signal into pieces, adding various colorations and phase shifts along the way. The pieces are distributed to different drivers, each of which adds another unique set of characteristics. We then expect these fragments of electronic signal to be brought together again in a continuous, coherent reproduction of music. We agonize over different cable routings or which contact cleaner to use, and yet we calmly accept this grotesque sausage-making way of building speakers. It's ludicrous.
