Stax headphones are rarely changed, but every time there is a significant improvement in the redesign, just like the SR-507 sent this time, the shape retains the square housing design of the Stax headset, and the head has a 10-segment height adjustment device. I believe that anyone can find the most suitable wearing height. This headband uses soft fabric and feels very soft to the top of the head. The earmuffs are made of lambskin, which is soft and does not have artificial leather. a stuffy and airy feeling.

In terms of diaphragm, the new version uses an elliptical diaphragm and still uses a static principle to drive the diaphragm in a push-pull manner. The new diaphragm is very thin and is not susceptible to temperature and humidity, providing a finer high frequency. In addition, the SR-507's headphone cable has also improved, in addition to the use of annealed high-purity 6N copper, but also added silver-plated wire, this should be for tuning considerations.

The original factory recommended SR-507 with SRM-600 LIMITED expansion machine, the two look similar in appearance and price, the price is close. SRM-600 LIMITED also has more input and output terminals, it is also very convenient to use. It promotes SR-507 The performance is even more remarkable, no effort.

In the actual audition, I first put in the CD that I usually listen to. I found that the sound of SR-507 is slightly different from the impression of the Stax earphone. The thickness of the sound has obviously increased a lot. The SR-507's intermediate frequency is enough to follow. The thickness of the dynamic headphones can not be described as full and thick, but it is already acceptable to most audio fans! Will the high frequency lose the unique charm of Stax? This is SR- 507 is awesome. I played Stax's own "Dummy Head Recording" CD. The details of the sound are still rich. The degree of sound field is not shrinking compared with the past. Many people appear in the first track. The voice of the conversation is the same as the situation that can cause people to misjudge the "someone" around.

If you change to the general pop music? In fact, it is also very good, the singer's voice is more charming than the dynamic headphones, but also more lively. If it is the previous Stax headphones, the drum sound will be a little loose, but SR The drum sound of the -507 has a shape and will not be scattered at all. If you want to test it, I am afraid to use a record such as "Ghost Taikoo", but who will listen to this type of music with headphones? In short, use Listening to pop music in SR-507 is also a different style of enjoyment.

As for classical music, it is Stax's strength. SR-507 pulls up the charm of string music. Even if people with expensive systems at home, they can't help but buy a set of Stax system in the study. In fact, many enthusiasts are In doing so, because the Stax headset still has the sound characteristics that the big system does not have. If you have to pick up the shortcomings of the SR-507, it is less the impact of the dynamic headphones, and lose a little low-frequency rhythm.
