SBC - the default sub-band coding for all Bluetooth headphones.There are 3 main audio codecs when it comes to headphones and sound quality: However, most Bluetooth headphones behave like the Bose QC35, with pretty much the same frequency response for both wired and wireless. Low bass is a bit higher when used wirelessly, and there's a roll off in the treble range that makes the MDR100x sound a bit more closed and less airy than when used wired. In this case, the Sony MDR 1000x show the most noticeable changes between wired and wireless. However, trained ears or more critical listeners may notice the slight variations in the frequency response as shown in the frequency response graphs below. Thanks to the improvements in Bluetooth technology, a lot more data can be streamed over the wireless connection, so the audio quality does not change much. In most cases, the differences are so small that for most casual listeners, it wouldn't matter whether the headphones are used wirelessly or wired. Results: As you may have noticed, the differences between wired and wireless in terms of sound quality are very subtle.

Below are a few audio samples of headphones playing audio both wirelessly and wired.
We compare Wired vs Wireless headphones based on sound quality, latency, and range. Who should buy it: Listeners that will use the headphones for latency-sensitive applications such as recording in a studio, gaming, and watching high frame rate content. What it is: Strictly wired closed-back headphones that must be used with the audio cable.
