Hello Head-Fi, I recently purchased a pair of ear-buds from a friend of mine. As soon as I started to listen to these ear-buds, I noticed how muddy the bass was and how the bass almost felt like it ate away the mid/treble. I removed the ear-buds to see if there were any signs of counterfeits and that's when I realized the Klipsch logo on the side of the ear-buds were completely worn off. I searched on the internet and came across this thread which had people with very similar cases to mine. I confirmed my S4s were indeed fake and decided to upload photos and give a warning because not many people are aware of this. So here are some photos. Fake on left. Genuine on right. The nub where the tip fits around is very smooth on the fake S4s unlike the genuine S4s. The case is a little bit taller and shinier on the fake tin box for the fake S4s. The "V" shape underneath the Klipsch logo slightly overlaps the "K" on the fakes. The "V" shape underneath the Klipsch logo slightly overlaps the "h" on the fakes. The "V" shape on the actual ear-bud itself is slightly larger on the fakes. The Klipsch logo on the side of the ear-bud wears off easily on the fakes. The genuine S4s do not come with a cleaner(?)
