Sennheiser - HD 550 Over-Ear Open-Back Wired Audiophile Headphones - Black

Absolutely fantastic headset! This is a great headset. Sound is amazing. Sound get even better with a dac/amp. So happy with this purchase.

With everything trying to switch to wireless nowadays, I am more than relieved to see one of my favorite audiophile brands continue to support wires. In my opinion, no matter how the tech is, it simply won't match the sounds direct connections can produce. Everything from sound quality to comfort, Sennheiser delivers in every aspect. Included is the headset itself with a generous ~6ft of cable, screw on 6.3mm adapter and a nice carrying bag (can't really call it a case). Literal plug n play. I have been using mine generally for 2 uses, my PC and my AV Onkyo Receiver. Sound quality just blows me away on how crystal clear it sounds. Bass, mids and highs are *chefs kiss* as to be expected. Comfort for the over ear headset is another major plus. I wore them through a 6 hour game session with my friends and NOT once did they ever feel uncomfortable. I think also because of it's light weight, I totally forgot I was even wearing headphones. My ears never felt hot as some brands do and personally I love how they chose not to go with leather and stayed with a super comfy cloth. In all I just want to say you get what you pay for and the 550s are 100% worth it. I made the switch from my old daily drivers and haven't even bothered looking back once. I would high recommend Sennheiser's in a heartbeat.

If you're a bit of an audiophile, you've probably heard of Sennheiser. They have created some of the best audio equipment for the past decades. I have owned my fair share of headphones and earbuds from them and I was always amazed by the excellent quality of their devices. Are the HD 550 good? Bad? First, let's establish a couple of things. The first would be that no matter how far advanced wireless audio has come, I will never entirely surrender wires. Sure, earbuds, gaming headsets, that's all fine, but for music and movies or audio production, there is only the way of the cables. Second, nothing comes close to over-the-ear headphones. You can argue as much as you want, but to achieve the best results, you have to cover the ears entirely. The unboxing was pleasant, with the headphones wrapped in a soft carry/protective bag. Note that the 3.5mm to 6.3mm is already attached to the cable's plug. Simply unscrew and pull it off and you're good to go. Now, to test the headphones, I have used several sources. most of them devices you probably have in your home: An Onkyo Amp with optical source, a gaming laptop, a content creator laptop, a mixing console in my small home studio and last but not least, a guitar amp. I also have very eclectic taste in music, so I was able to test the 550 HD with classical, pop, EDM, rock, metal and more genres of music. The results were incredible. Not only can you hear *everthing*, but it's clean and clear, with full and round basses, punchy mids and delightful highs. Raw sound, without a pre-amp or an amp directly from the source brings out the best of these babies. I fail to find something bad to say about the quality of the sound. It's simply excellent. The design team did a great job as well. The headphones are sturdy, yet very comfortable to wear, the soft suede type ear covers are wide enough that they don't cause any discomfort to the ears (i.e. chaffing). Since the 550 HD are wired, there's no batteries inside which chops off a bit of weight as well (and you don't have to remember to charge the darn things). I can't express how incredible the sound is. I own headphones that are way more expensive, yet most of them don't even come close to the Sennheiser HD 550. Sure, it's a chunk of change to spend on headphones, but the thing is, you really get what you pay for, and in this case, you absolutely do. You get excellence and decades of R&D and engineering with the goal of offering the best sound possible, a pure sound.

Sennheiser is know for their great audio equipment and they continue that with their headphone line in the HD 550 open back headphones. The HD 550’s are what I would expect from Sennheiser at this price point. In The Box In the box for the HD 550 is the headphones, a carry bag with cinch cord, and a screw on 3.5mm to 1/4” screw on adapter. The cable for the headphones is about 6 feet long. Plenty long enough for me, but even if it wasn’t, I would just connect one of the many extension cables that I have accumulated over the years. Construction The HD 550’s have a plastic headband with a leather wrap that has padding in it. There are also 3 raised dots on the outer part of the left ear piece. There aren’t any on the right, so I know which side is which just by touch. A nice though on Sennheiser’s part to keep users from having to look on the inside of the headband to see which side is which. The ear pieces have a metal mesh outside. On the inside it has padding that is soft and gives added comfort. The detachable that comes with them is very flexible and is long enough for me to sit back and little from my computer when playing through audio recordings. The cable is straight unlike my Sennheiser HD 280 Pro’s. The 280’s have a very heavy coiled cable, but the 550’s cable is light weight. The construction of the 550’s is geared towards low weight unlike my 280’s which are heavy and aren’t quite as comfortable when wearing for long periods of time. Use Of The HD 550’s These headphones are surprisingly lightweight. I expected them to weigh more, but Sennheiser has done a great job at keeping the weight low. I was wearing these for hours at a time while editing videos and listening to music and it was as if they weren’t there. The audio from these sounds really good. They are very clear and produce a rich sound. Final Thoughts I’m very happy with the HD 550’s. I’m surprised at the weight while still having a rich sound quality. I’ve always liked the quality and performance of Sennheiser products. They don’t disappoint with the HD 550 Open Back Headphones. If you are looking for open back headphones, then definitely consider the HD 550 headphones as possible option.
