Pros: Really clear sound and even better if you do the foam mod on them. I use mine on my Onkyo amp at night for great sound quality and dont have to comprise sound quality with game headsets.
Cons: If you have a android they may sound low if you dont have a mini amp. I heard that iphones have the power to run them. If your phone doesn't have the power to run them so they get loud enough and retain their bass. FiiO sales a mini amp on this site that will run them great.
Conclusion: I had approximately one month using the HD558 and I am so impressed with the quality of the sound and comfort it provides. A full broad frequency spectrum so balance that I use it every day. I hate to take it off, but I have to go to work.. I have only one suggestion for any potential buyer.
GREAT balanced sound, amazing soundstage for gaming.

Conclusion: Very nice and balanced sound signature, still has that satisfying bass. Soundstage is really amazing for gaming (CS:GO, Battlefield 3/4) and movies. Also very comfortable with its soft velour cushions on the ear cups and the headband.
Summary: I have been a Sennheiser customer for nearly 8 years and this particular pair of headphones are everything they were promised to be. My old pair of phones (HD555's) lasted me for 6 years of travel and rough ware. My old headphones are built relatively similar to the HD 558's.
Pros: Great sound quality. Reasonably affordable for high definition headphones. Comfortable
Cons: They aren't noise cancelling, but don't advertise to be
Pros: The quality of these headphones is absolutely phenomenal. If you are looking for headphones in this price range, these are a great pick. On top of the sound quality, these are the most comfortable headphones I have ever worn. I fell asleep while wearing them on the first night of having them and ...
Cons: The only fault I have with these is not with the headphones themselves, but with the audio sources that I use. My PC does not put out enough power to fully utilize these headphones, so I went ahead and purchased an amplifier to allow me to use these to their highest potential.
Summary: I have these paired with a SoundBlaster Z soundcard which runs to a Fiio e9 headphone amp (used as amp but also to control sound levels from desktop to speakers or headphones) and works wonderfully. (highly reccomend both items)
Pros: Quality construction Great Soundstage High quality sound reproduction Highs and mids are excellent Highly reccomend as an intro audiophile pair of headphones.
Cons: A little tight bellow my ears (big head) Bass is a little weak although that can be fiddled with a little bit with soundcard. Cord is VERY long - this may not be an issue for you depending on how you want to use it, I have just zip-tied a few loops to shorten the cable. (Why has Sennheiser not re...
Summary: I would recommend these cans to anyone who values sound quality and clarity to anyone.
Pros: These head phones are hands down the best headphones i have owned. The range of sound and clarity is superb. Super light weight and comfortable, i can wear them all day without any discomfort or headache.
Cons: The only downside the headphones have is a lack of thump. Dont get me wrong, they have bass, and an excellent range of it, but if you want brain rattle, they dont have it.
