The HD 600 is the audio purist’s choice for reference playback. An instrument of Sennheiser’s passion for perfect sound, it is globally recognised as the standard for analytical high-fidelity listening - even 20-plus years after its release. The foundation of the extraordinarily clear sound of the HD 600 is its’ open acoustic design and the revolutionary transducer, which has been computer-optimized to reduce partial vibrations, which are responsible for a multitude of distortions.

The HD 560S indulges the audiophile evaluating their music’s entire journey through the audio path. With linear acoustics and exceptional low-frequency performance the HD 560S was crafted for the analytical audio enthusiast. This open-back headphone is tuned to reveal every detail in your music without sacrificing the gratifying bass response. When combined with its ultralight chassis and luxurious comfort, it’s a breakthrough value in reference monitoring.

We believe in giving high-performance audio enthusiasts the purest headphone listening experience possible, even when their surroundings are far from perfect. The closed-back HD 620S caters to this audience by providing distraction-free listening without compromising on natural presentation. The reference-grade 42mm transducer and ultra-light 150-ohm aluminum voice coil deliver exceptional impulse response, bringing the listener to the front row of their music. Where many closed headphones struggle, the HD 620 excels, preserving the detailed, smooth sound the 600 series is known for while providing expansive, panoramic imaging. To mimic the presentation of loudspeakers, the HD 620S features angled transducers nestled in a remarkably open baffle. Even in complex music, bass, mids, and vocals are delightfully layered with distinct instrumentation and nuance. The steel-reinforced headband sliders and earcup covers ensure long-term durability while reducing unwanted resonances, all in a lightweight chassis designed for all-day use. Supple artificial leather earpads offer both a comfortable touch and superb acoustic isolation. The HD 620S includes a detachable 1.8 m twist-lock cable with a 3.5 mm plug and a 6.3 mm adapter.

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.
