Excerpt: Great set of headphones. Feel very light on the ears. Sound is pretty good. I wish the connector on the end did like my Audio-Technica's and had a better adapter for going from 1/4 jack to the 3.5mm jack. The Audio-Technicas's you screw off the 1/4 adapter. These come with an adapter that makes the plug bulky.
Summary: First review but here goes :P
The Sennheiser HD 558 comes with a 3m detachable cable, a 6.5mm to 3.5mm converter and the headphones themselves.
Comfort and Build: Although the headphones themselves are made entirely of plastic it doesn’t feel like the cheap plastic. In fact the build seems solid enough to take light abuse but I really wouldn’t recommend anyone stress test these to any high extent. They do however feel like a well-constructed pair of headphones.
Pros: Smooth mids, non-fatiguing but interesting highs and overall comfort
Cons: May be bass light which may feel a little muddy, ungodly plug and clamping force
Summary: My chain: Lossless -> Foobar 2k -> HifimeDIY Sabre DAC -> E11
The HD558 are doing it for me right now. I was not blown away, but they really don't do anything wrong. The bass is not boomy but does bleed a tad, not ideal for classical but it's not hugely problematic.
The mids are nice. Never overly resonant, just enough bite to give realism but not intrusive. Imaging is very nice, but transients are a little weak.
Pros: Mostly neutral tonality, quality timber meets or exceeds expectations for the price, good presence across the spectrum, great all-rounders
Cons: Sennheiser veil, bass can bleed a little and doesn't go all the way down, mids not always as forward as I would like ideally
Summary: I bought these as a replacement for my HD500's which were long in the tooth but lasted 12+ years. I mostly used them for online gaming. The HD558's were a natural replacement. The main thing I noticed is they are comfy. At first they feel a little tight so I was concerned but pretty soon you forget they are even on. One annoyance is that the 2.5mm fitting into the actual headset requires a twist to release or fit.
Summary: These headphones are by far the best I have owned. The sound is great for music gaming and movies. The cable that comes with it is very long and even though it comes out of the headphones it is a special cable which has a locking mechanism and is very hard to replace or find a smaller length online.I did manage to find a replacement online it has to be sent from China and cost about £12 with postage it hasn't arrived yet so I cannot comment on it or if its worthy of the...
Summary: Loving these headphones. The sound quality is above what I expected at this price. There's no sound cancelling, but when you have sound pumped into them you're not going to notice. Full highs, mid, and lows with a lovely projection that makes the sound feel wider. Like most outputs the benefit from adjusts to a graphic equaliser. In vanilla mode they are more than capable of warmth and clarity.
