I’m going to review my Sennheiser HD 558s that I had received for Christmas as a gift from my parents. These headphones were great right out of the box. On Christmas morning, I unwrapped it, took it out and plugged it straight into our huge receiver, and I heard things out of these headphones that I could never hear before. If you plan on buying a pair of 558s, please be aware that these headphones have a 3m long cable, that ends with a 6.3mm jack (although it comes with an adapter for 3.5mm), and these headphones will not sound as great if they’re plugged into a computer (without a soundcard), or a phone. If you are going to use such things with these, please look at maybe getting a headphone amp/usb dac, and for use with phones – look at portable headphone amps.
The Sennheiser HD 558s are open headphones, meaning that it will give a more natural or speaker-like sound and more spacious “soundstage” or “soundscape”. I find that my music is a lot more enjoyable on open-back headphones… But one problem with open headphones is that they leak a lot of sound, which can be a bad thing for people who like to enjoy their music in public or at school.
The sound quality on the 558s is outstanding! When paired with a headphone amp, these produce crisp and clear sound with great instrument separation! I can differentiate between each instrument such as the drums, guitar, piano and bass guitar without any trouble.
Overall, these headphones have an amazing sound-stage, outstanding sound quality, and great instrument separation. If you listen to genres such as rock, jazz and classical music, I’d definitely recommend you look at these headphones.
If you’re want cheaper headphones with a little more bass take a look at the Sennheiser HD 518s.
