As you can see from the chart there are quite a few similarities between the Audio Technica ATH-DSR7BT and ATH-DSR9BT wireless headphones. Both are over-ear headphones utilizing Bluetooth 4.2 or NFC for connectivity. They also both have the custom 45mm True Motion Drivers. Using the Pure Digital Drive technology these unique drivers are able to translate digital audio directly into motion in the driver through a special chipset. This eliminates the need for a digital audio converter keeping the sound pure and clean.
You can also see on the chart other similarities in these two headphones like wireless range, battery life, on-board controls and no aux cable. Instead the ATH-DSR7BT and ATH-DSR9BT have a micro to USB cable for connecting directly to your computer for pure Hi-Res audio capabilities.
The main differences between these two headphones comes down to a few vital specifications as well as the sound and fit.
First the Audio Technica ATH-DSR7BT has a frequency range of 5Hz to 40,000Hz while the ATH-DSR9BT has a range of 5Hz to 45,000Hz. Another difference is the ATH-DSR7BT has an impedance of 35 Ohms but the ATH-DSR9BT is at 38 Ohms. This is a small but noteworthy difference. You’ll also notice the DSR9BT comes with a nice hard carry case while the DSR7BT has a carry bag. The only other difference in specs is the design and build. Both headphones are built with similar parts and padding but have notable differences in design and color.
So the sound is really where these two headphones set themselves apart. Comparing both the DSR7BT and DSR9BT head to head with a DAP using the Qualcomm aptX coded I went back and forth through some familiar tracks in uncompressed and lossless formats. What I discovered were subtle yet significant differences in the sound signature of each headphone. The ATH-DSR7BT was crisp, relatively balanced yet a little bit punchy too. The ATH-DSR9BT had a much wider, open sound and the clarity the higher frequencies was much more clear due to the added 5000 Hz on the top-end of the spectrum.
Although both headphones seem to be built similarly they are in fact a little different. The DSR7BT feels a bit more like an MSR7 headphone. The padding is comfortable and snug. The DSR9BT however is a bit more comfortable. It has a slightly wider headband and just feels nicer around the ears.
Both the Audio Technica ATH-DSR7BT and ATH-DSR9BT are incredible new headphones that push the limits of wireless technology. I would even consider them to be audiophile quality headphones which is tough to do when going wireless. When it comes down to it, there’s a lot of similarities in build, technology, features and sound with the DSR7BT and DSR9BT. If you’re looking for an affordable, wireless audiophile headphone the ATH-DSR7BT will definitely fit the bill. But if you’ve got a little more cash and want added comfort, a wider sound spectrum and a premium case for travel, the ATH-DSR9BT will definitely thrill.
