First of all, this isn't that kind of review the author writes usually.
The Beyerdynamic DT 302, also known as DT302 or DT-302, are high quality
open style dynamic stereo headphones which have been available on the market
since the middle of 1970's. They competed very well against other high end
headphones such as the Sennheiser HD 414. By the way, those HD 414
were the world's 1st open style dynamic headphones patented in 1967 and
released in 1968. In a matter of fact, they met a fantastic success on
the market. The DT 302 were introduced in 1974. Although well worth
the money asked for, their success on the market was rather limited.
The original 2000 ohm Sennheiser HD 414 were replaced in production by
the 600 ohm model of the same name in 1983 and by the 52 ohm 50th Anniversary
Edition in 1995. There were over 10 million units sold making this model one
of the most popular headphones of all time. The Beyerdynamic DT 302 didn't
survive for so long in production and were phased out somewhere in the 1980's
in favour of more advanced models. Anyway, the DT 302 are the 1st open style
headphones by Beyerdynamic and deserve their place in history. Frankly
speaking, there is nothing new to say about these headphones. The whole idea
of this review is to gather information on this nice audio gear and keep it
in one place. So, here we start.
Beyerdynamic DT 302 Headphones in Box|
(click to enlarge, 1.0Mb)|
The Beyerdynamic DT 302 are 600 ohm open style dynamic headphones with
30mm drivers. Note what's written on the top of the box — Beyer Dynamic.
Hören in seiner schönsten Form. — which is German for "Listening at its
best." You see, Beyerdynamic was spelled Beyer Dynamic back in those days. The
box also says in English "a quality product made in W.-Germany" — that
was West Germany. No manual included and you're not supposed to need any. This
version of DT 302 comes with a 6.3mm (1/4") TRS jack, though there are
versions with other kinds of connectors such as 5-pin DIN. Frequency response
reported is pretty much standard, 20Hz to 20kHz. The headband is made of black
plastic entirely. The whole construction is very light in weight. The cord's
length is about 2.5 metres.
Beyerdynamic DT 301 Headphones in Boxes|

The Beyerdynamic DT 301 is a single ear dynamic headphone. The
internals are exactly the same to the DT 302, though the boxes pictured
above and official advertisements report frequency response of 30Hz to 18kHz
for some reason. The rated power is about 7mW at 2.1V applied. All three
DT 301 units on the photo above come with 3.5mm (1/8") TS mini-jacks
which are mono capable, though there are modifications with DIN connectors
as well. The 50 ohm version of DT 301 was also manufactured.
Frequency response of the Beyerdynamic DT 302 and DT 301 hasn't
been evaluated due to lack of appropriate equipment. In general, the author
considers bass performance to be somewhat weak, though middle frequencies are
excellent and treble is very good. These headphones are definitely not the best
find for bass intensive music genres such as rock and metal. On the other hand,
classic music sounds really good with them. Although a particular experience
may vary, you probably won't regret listening to your old favourite vinyl
recordings with these high quality Beyerdynamic products.
Here is a scanned copy of the official booklet on these headphones released
in 1974 for the United States.

In 1937 we were the first with a headphone that has not only become a legend,
but is still considered to be the finest dynamic headphone in the world. We
have even kept the original designation to this day - the Beyer headphone
Chosen to judge others by, the DT 48 is a DIN standard 45620 and has
revolutionized the recording and film industry.
In 1953 record store customers first enjoyed our telephone type DT 49
headsets and so the music bar was born.
In 1955 we created the first miniature dynamic earphone and with it typists
could transcribe dictation more easily.
In 1969 we pioneered the technique of modular headphone construction with
our models DT 100 and DT 480. These headphones, with their total
field serviceability, have been of immeasurable assistance to education and the
broadcasting and recording industries.
In 1973 we brought to you the first European quadraphonic headphone - the
BEYERDYNAMIC DT 204.
In a few words, we hope that we have shown you that we understand something
about headphones. "Open High-Velocity" headphones are nothing new to us, only
Headphones from BEYERDYNAMIC belong to the ranks of the world's best and
now with the advent of the "Open High-Velocity" DT 302, we can offer you
the optimum headphone for every conceivable application.
The result of BEYERDYNAMIC "Open High-Velocity" transducer research is two
fold - the stereo headphone DT 302 and the single earphone DT 301.
With wide frequency response from 20 - 20 000 Hz (in fact beyond the range
of audibility, but all important for the reproduction of the harmonics which
make up the complete musical character of the piece) plus the ability to
withstand, without distortion, high levels, and a weight that you can simply
forget, our DT 302 and 301 phones are the best lightweight headphones
"Open High-Velocity" headphones from BEYERDYNAMIC fit every head and match
every system. Convince yourself - try them at your audio dealer. Ask for the
headphones from BEYERDYNAMIC, the people with over 37 years experience in
pioneering, developing and manufacturing the finest headphones.

A light (in fact the lightest) stereo headphone available, working on the
"Open High-Velocity" principle.
The DT 302 can be worn for many hours without fatigue because it
presses on the ears only with a quarter of the pressure of conventional
headphones. The result of which is that the wearer is completely unaware of the
presence of the DT 302 and concentrates only on the music which he hears
in a most natural way.
Its unbreakable headband with ultra-soft foam cushions adjusts to suit any
The balanced, startlingly realistic sound reproduction of the DT 302
is the new formula for full musical enjoyment.

Finally, here is a U.S. retail price list on Beyerdynamic headphones as
of the 1st of December, 1976. You can see the DT 302 carried a price tag
of 24.95 USD and the the DT 301 was priced at 16.95 USD. Although may not
seem expensive especially compared to the legendary DT 48, that's still
about 110 USD and 75 USD respectively by purchasing power in year 2019.
The price list was issued by Meteor Light and Sound Company, a division of UK
based Hammond Industries Inc.
