- Fantastic sound, clean open, well balanced. Perfect for use at home.- The main issue is with the bad cables: they are too rigid and transmit sound when knocked. Annoyingly, they are proprietary, and with (unnecessary) locking system. I cannot even use a previous Sennheiser cable with volume control.- Minor issue: it gets warms around the ears. They feel very plasticky for the (high) price.- Durability: only had the set for a month so cannot report on durability.Overall good but those cables need to be addressed if you want repeat purchase from me.

Absolutely gorgeous piece of audio equipment. The beautiful ivory and tan finish has a wonderfully nostalgic feel to the design.But beyond that they're an exceptional piece of equipment. The sound balances are unparalleled in any of the HD300-500 range or the GSP range. I upgraded from the GSP350 to these as im no longer gaming and it made the prior experience sound like I was listening underwater, there are notes and tones and a level of balance that is just mind blowing, I have truly never experienced anything like these before even from other companies in the same price range.In summary, gorgeous to look at, gorgeous to listen to, cannot recommend the HD599 highly enough. Sennheiser you have truly made a piece of Audiophile equipment at an insanely low price.

Amazing! Worth its price when on sale!

One of my first Sennheiser headphone. Definitely worth the price. I've used JBL and Sony headphones but they're not as comfortable as this. Genuinely not notice they're on my head sometime due to the light weight + open back style. Which may be a problem if you're used to the generic bluetooth like from JBL and Sony, in the beginning I would forgot that it's connected to my laptop and I would just walk away and yank my laptop... Once you're used to it, it's definitely worth it.

Excellent Triple A League Headphones

I've waited until I have about 60 hours on them to make any judgment.. They are very clear but compared to my ancient HD600s I find they lack extension, detail, and depth. This is not to complain. They are very musical although the Sennheiser veil seems more apparent especially with some performances. Bass contrary to many reviews is more than adequate for my ears and genres of music (classical, acoustic, choral). The highs thankfully are not as pronounced saving me from listener fatigue. The 599s are a bit more colored and warm. They are comfortable but a little tight.. The clarity is phenomenal and clearly the headphones' strength. The soundstage is compressed compared to the 600 but not to the point of being a disaster. I'll use the 599s with my computer to ... MoreI've waited until I have about 60 hours on them to make any judgment..

The music is compressed so you lose a lot anyway. They are worthy of the high accolades I have read, but they are not in the same league as high end cans. The 599 is a very good for an under $200 headphone. I am very happy with them and spent hours A/B in them with the 600s to see which one I'd make my primary. The 600 remains the champion, but the 599 is rightfully in the silver medal position.

Excellent set of headphones from Sennheiser

Great headphones from Sennheiser. Sound quality from these open backed headphones provides for a well balanced open sound and a spacious feeling for the overall sound. Comfort is just right a lightweight at 252gms. Easy enough to use with as a bluetooth option with an adapter like Airfrex SEHD. Build quality is good. Feels robust enough.

Excellent sound from these super comfortable headphones

I purchased these Sennheiser headphones recently having previously owned a pair of Pioneer Bluetooth ones which I wasn't that happy with (too heavy, uncomfortable to wear and not enough base). These HD 599s are in a different league! Really comfortable and just the right amount of bass and treble sound. You can hear every note even from 128kbps mp3 files direct off a laptop. The headphones seem to balance the output of all files perfectly - I like all sorts of music from Dvorak through to Dire Straits through to Deep Purple! Sound quality is wonderful. I did lots of online research before deciding on these - I wanted a mid priced but quality product, and these Sennheiser's are perfect for me. I also wanted a wired product (as I read that quality is usually better ... MoreI purchased these Sennheiser headphones recently having previously owned a pair of Pioneer Bluetooth ones which I wasn't that happy with (too heavy, uncomfortable to wear and not enough base).

I also wanted a wired product (as I read that quality is usually better than wireless) and these headphones come with a choice of two cables - a shorter one with small 3.5mm jack plug and a long 3m cable with an older style big plug. I have only used the short one which is ideal for my laptop or phone. All in all - super happy! And thanks to eBay I got them at a good price too!

Finally found the most comfortable headphones

The audio is excellent. I have been able to hear so much more sounds in music that I have not been able to hear. On top of that, they are the most comfortable headphones I have ever worn. I have always had an issue with long headphone sessions. Headaches would start about an hour into wearing any headphones. With these, I have been wearing them for about 4 hours and I feel like totally fine.The open back nature of these headphones is a plus for me too. I like to hear what's going on around me at home, so if you're the person who needs to hear a knock at your door, or a weird noise in the night, you can easily hear everything around you.

Great for $130

These headphones are a great entry to the detailed listening headphone space if you can get them for $130-$150. They can be powered by a phone or laptop. The options that are the next step up need an additional purchase or a Dac/Amp. That said an upgrade will probably run you $300 for HD6XX and an entry level Dac/Amp. Thats why these are a great entry at $130-$150.

I wouldn't recommend it.

The headphones feels little too cheap but then it is a budget price so I can't complain. The sound quality isn't as good, especially when I have tested cheap headphones for $30-40 that sound better. The bass is little underwhelming, but the open back does make it sound more open at least.Also don't expect to wear this for more than 10 min unless you have unreasonably small head. This will absolutely crush your head, maybe you might need to break into it.Look somewhere else, this ain't it.

Pretty Flat

After trying several pairs of headphones for home recording, I realised that I needed open back to hear for a more accurate representation. These will work nicely. Fairly flat response with no frequencies sticking out in any obvious way. The bass is good but not excessive. There is a slight mid scoop from maybe 300hz-1Khz and a bit of an exaggerated airy high frequency boost around 10khz. Overall a fairly neutral and pleasant sounding set if not "prettied" up a bit. Very comfortable and easy to wear for long sessions. The difference from $100 level to $150 is remarkable! I'm curious to hear what the next $100 or more would sound like?
