High-performance headphones from Koss

 Koss is one of the most established earphone producers in the US, 

also, it has various models that have stayed in the line for quite a long time. I'm pondering the Porta Pro on-ear earphones and the Pro4AA over-the-ear earphones, to name two. 

So when Koss presents new models I'm listening eagerly. The SP330 on-ear and SP540 over-the-earheadphones sport a crisp look, and I believe they're entirely nice looking. Both earphones accompany zippered convey cases that make an abnormally decent showing securing the earphones. Both earphones have 52 inch long client replaceable linaks, and both need mic/remotes for telephones. They're 35 Ohm impedance outlines. 

The SP330 ($129.99) on-ear is littler and lighter than the SP540 ($149.99) over-the-ear earphone. The sound is transparent clear, the SP330 is one of those earphones that truly developed on me. Bass was decent and full, yet never thick, element differentiations were enthusiastic. Vocals are prompt and extremely display, highs are a little bit unpleasant, yet absolutely on focus for an earphone in the SP330's value class. The delicate ear cushions were genuinely comfortable, however I would have favored somewhat lighter weight against my ears. The SP330 creases level for conservative stockpiling, and I enjoyed that the ear containers are strengthened with anodized aluminum. 

Moving onto the SP540 over-the-ear earphone there's a sizable increment in bass, and the "D-profile" flexible foam pads all the more nearly take after the forms of human ears than more normal round or oval ear cushions. I discovered the SP540 more agreeable than the SP330, however that is valid for a considerable measure of over-the-ears, for me. 

The SP540 additionally includes external ear mugs strengthened with anodized aluminum, and the earphone overlap level for capacity.
