Beyerdynamic DT 235 Headphone

A Great Sounding Brick
The DT 235 is a general utility, sealed ear-pad headphone, good for use in libraries, museums, point-of-purchase displays, and anywhere you want a reliable headphone that delivers a natural and pleasant listening experience. Their durability also makes them just the thing to give to a youngster who's hard on his/her gear.

Built to take a beating, these cans are a simple design with a fixed headband, swiveling cups, and self-adjustable head-pad. The cable is long at 2.5m (~8 feet), which can be very handy in business/institutional environments. Ear cushions are velour and replaceable.

Available in black or white, the DT 235 is not a pretty headphone --- that can be a good thing, though, as it's a bit less likely to get pilfered in business/institutional use. The headphones are light, and relatively comfortable and secure on the head. Isolation from outside noise is pretty poor, so these cans will probably not isolate enough for commuting applications.

The sound of the DT 235 is very good for this type/price headphone. Like virtually all sealed ear-pad cans, the bass does not have good extension into the lower octaves and sounds a bit muffled. The upper-bass through midrange is well balanced, however, and brings good heft to the tunes. A slightly withdrawn lower-treble causes voices and strings to lack presence a bit, but mid-treble remains at about the right level or a tad above, bringing just a bit of zing to the music, though definitely not overly bright. I would characterize these cans as very good sounding for this category.

Look, there's not a lot of glamour here; these headphones are about as plain as they come. But their low price, very good sound, and rugged durability make them a great utilitarian headphone for lots of high use-and-abuse applications. Strongly recommended.

...reportedly these cans aren't quite as rugged as they might seem, with the swivel joints being the weak point.

My DT231Pros (technically the same, I assume) had some foam fitted in the cavity behind the drivers for good measure. Can't hurt to suppress cavity resonance a bit. Easy to work on in general, swapping earpads is a breeze.

I'd call the sound "look at me, I'm hi-fi". Isolation is lousy indeed (which is not surprising if you look at earpad construction, the mounting hardly is airtight), sensitivity is only average, but output impedance is largely irrelevant. I was doing some testing lately and found them to handle pretty respectable levels.

Oh yeah, and they're super comfy, unlike a number of other mid-sized supraaural cans which seem to be constructed for people with circular ears (must be some extinct tribe).
