Koss BT539i Review – UPDATED 2021

The first impression of Koss BT539i headphones, it doesn’t give you that premium feels or look, most probably because of the plastic casing. Due to this shortfall, it is actually lightweight and comfortable to wear, the inner soft cushions feel just right on our ears. We tried to shake our heads with little more exaggerated movements and the wireless headphones stays in place. Having comfortable headphones is very important, especially when you are on the move while wearing them, each step you make could be a nightmare if the headphones are heavy and uncomfortable.

Koss BT539i is designed and made to be portable, as you can fold it flat and easily keep it inside your bag. It has Bluetooth 4.0 where you can connect to your mobile device and start streaming music. Since it has an inbuilt microphone, you can use this BT539i to answer phone calls. The controls are conveniently located on the right side, where you can control the volume, navigate songs, answer calls, and more. The battery life is more than enough to last you the whole day, with 12 hours of playtime at moderate volume. Even if the battery runs out, you can still use the detachable analog cord, to connect your Koss BT539i to your mobile device to continue listening to your favorite songs. The D-profile cushions really are comfortable but the headband will really depend on the individual’s head size though, as it is thin and does not have padding.

When answering calls, the voices can be heard clearly and no stutter, as there is a stable Bluetooth connection. The other party can hear us clearly as well, which means the built-in microphone is good too. But in an open area or busy streets, the microphone does pick up noises coming from the environment which does interrupt your phone conversation. Now comes the sound quality review when playing back music, the midrange sound reproduction is detailed and clean, the vocals sounded natural. The higher frequency tends to be a bit unclear and muddle at times, but the bass reproduction is good and better than expected at such a price point. The scale of the soundstage is decent and the signature sound of Koss is there as well. Koss BT539i is capable of reaching high volumes without much distortions.

The sound quality is really impressive, if only it comes with apt-X, the streaming quality would have improved. You can go for direct connection using the analog cord for slightly improved sound quality but does beat the purpose of being wireless headphones. If only it is more comfortable to wear for a long period of time and a microphone that catches the user’s voice more directly, then it would be the perfect entry-level Bluetooth headphones. At such a price point, Koss BT539i has already exceeded expectations and well worth your considerations.
