About Kworld

You would be forgiven if you (like me) are wondering what the heck is Kworld as they are a relatively unheard brand. There are plenty of Chinese audio manufacturing companies that offer different drivers and housing combinations to companies looking to sell earphones under their own brand name.

That said companies still need to check and decide on what combo they would ultimately decide to sell under their own brand. I don’t know if Kworld took this route or they are making their own drivers but I suspect the former. Kworld is a company based in Taiwan and offers quite a few earphones which are at the lower budget end of the spectrum. The earphone on review today is the S28 which is a unique earphone in that it offers two caps that screw into the back of the housing which claims to offer two different sound signatures.

First Impressions…

The Kworld S28 has a standard accessories bundle though the Comply eartip is nice. While Comply tips are very nice and comfortable they don’t last very long and using them exclusively can cost a lot more than the earphone. Comply tips are more comfortable than standard silicon tips and the sound signature can change when using them.

One nice feature is the attached cable tie which can be VERY useful in tying up your earphone when not in use. The built-in mic with volume control is very useful in case you need to make minor volume adjustments, to pause/start the music and if you double tap the mic button you can skip to the next song. However, I should mention a few cautions. I have slightly weirdly shaped ears so comfort and fit are generally a bit of a problem for me with most earphones.

With these, I encountered a different issue where the seal would be too tight and the I couldn’t hear the music properly. I would have to loosen the seal in order to get optimum sound quality from the S28. This issue has been encountered by other reviewers so I am not alone in facing this problem. Once you do get a decent seal it generally stays put for a decent amount of time. However, with the long housings, comfort is average to below average. One way to alleviate this is to loop the cord over the ear.
