The Koss Pro4S may be the last studio monitor headphone you ever buy

[MUSIC] If you're a music geek looking for a pair of headphones that won't change the way your music sounds, well, these should be on your list. Hey, it's Justin Yu from CNET, this is a first look at the Koss Pro4S headphones. So these are actually studio monitor headphones, which means they're meant to be used by audio professionals. That's people like audio engineers, producers, musicians, and anyone else that demands pure sonic accuracy. But there's already a lot of classic reference headphones out there, like the Audio-Techica ATH-M50, the Sony MDR 7506s. And the Sennheiser HD 280s that have proven themselves worthwhile buys over the course of the last several decades. So before I get into how the Pro4S sounds, let's take a look at the build. In contrast to the older headphones I just mentioned, these have a really modern aesthetic that pushes away from those gaudy, bright colors so many headphones have today. Instead opting for a more subtle approach with important details like memory foam ear cups and super lightweight materials. Another key feature to note is that this comes with a detachable coiled cable that you can actually plug in to either side of the ear cups. You can also daisy chain another pair of headphones into the jack you're not using. So basically, two people can listen to a single audio source at the same time. So how do these measure up compared to the competition in terms of sound quality? Well their natural resonance worked really well for instrument driven music, but as expected pop music and other songs with artificial tones just don't have that same vigor as competing headsets like the Audio-Technica M50s. If you're someone that appreciates a range of versatile genres on your iPod, you may be more satisfied with a sound profile like those M50s. On the other hand, if you go into a listening experience prepared to hear your music exactly the way the production team intended, the Pro 4S Headphones won't disappoint. Especially when you hear about all the accessories that come with it, like this quarter inc adaptor and carrying case. You can read more details about that and more in my full review on CNET but that's gonna do it for this video. I'm Justin Yu. You just took a first look at the Koss Pro4S headphones. Thanks for watching. [MUSIC]
