  • Built-in mic and volume controls

I’ve been using these for a week now. I have a full review on the go, but wanted to post some initial impressions.

THE GOOD

  • The sound is brilliant. They are some of the best-sounding wireless headphones I’ve heard. I’m still trying to wrap my head around this pure digital drive technology, but I can say the result is great sound.
  • The wireless connections are great. I’m glad they support both AAC and aptX HD.
  • They are very comfortable
  • They look great

THE BAD

  • There is no ANC which is fine, but the sound isolation is also bad. I wore them in a Starbucks, and couldn’t hear any music.
  • I like to wear headphones in bed sometimes. These have a ridiculous LED light that flashes non-stop. I couldn’t find a way to turn the light off. It would definitely be annoying for anyone trying to sleep nearby

Overall I am impressed with them and would recommend them for listening to music at home (not great for the office / public spaces)


#3

How are they to charge? I heard they use micro USB. Is it convenient?


#4

Hahaha. It’s not the fact that they use micro USB that makes charging them inconvenient. It’s that the only micro USB cable that fits is the one they ship with the headphones.

I have at least 30 micro USB cables in my house, but their cable is the only one that fits.


#5

Ah that’s too bad, I hate when headphone manufacturer’s make you buy their proprietary cables to use their headphones. Sennheiser is notorious for doing it with their “locking mechanism” cables.

When you say they sound brilliant, are you saying they are bright? I found Audio-Technica really leans into that brighter, Japanese sound signature with their headphones. Does the ATH-DSR9BT follow suit?


#6

Very curious about this “1/0’s are pushing the drivers”…


#7

Haha. So am I. If you figure it out, let me know! AT is pretty cagey in their official description.


#8

Yup-- I reread that a few times and I’m still not sure what it means (or why it’s good).


#9

I didn’t mean “bright” I meant “great.”

Although I would say these have a typical Audio Technica sound. I would call the Japanese sound more “balanced” than “bright” though.

Since most wireless headphones are aimed at the mass market they are usually heavy on the bass. So, compared to most wireless headphones these have much less low end boominess


#10

Here’s some info on the Pure Digital Drive http://blog.audio-technica.com/technology-behind-ath-dsr7bt-ath-dsr9bt-headphones/ . Actually quite interesting, especially if they start to implement the technology on some higher end headphones!


#11

So after reading that, how would you describe the pure digital drive technology?


#12

How’s the sound quality compared to the M50’s? I notice they have the same size driver.


#13

I haven’t tried the DSR9BTs with a wire yet, so hard to give a direct comparison, but there is less sound isolation in the DSR9BT due to softer pads. That much I can say.
