Instead of a single attachment on the outer circumference of the transducer, both outer and inner edges of the “ring” are secured to the drive unit. The voice coil excites the diaphragm, connected to the v-shaped groove found near the center of the ring. A feat in itself, the voice coil is 40mm and wound in-house to ensure the shape and consistency is held to the highest standard.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"Sennheiser HD 800S High Definition Driver\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/v3_1.png?v=1689364640\"\u003e\u003c\/p\u003e\n\u003ch3\u003eSolid as a Rock\u003c\/h3\u003e\n\u003cp\u003eThe headphones’ vibration damping chassis and inert headband insert provide complete stability—what you put into the HD 800 S is precisely what you will get out of it.\u003c\/p\u003e\n\u003cp\u003eEach transducer is manufactured, tested, and measured to the tightest tolerance to ensure the most dependable performance out of the box.

The drivers are mounted at a precise angle, guiding the sound directly to the listener’s ears at their natural inflection point.

When finally combined, the vibration damping chassis, perfectly matched transducer systems and wide-open construction work in concert to provide the most striking soundstage yet. This orientation rivals or exceeds loudspeaker setups costing exponentially more—especially when room acoustics are factored in.

It can easily get sloppy or boomy and become a distraction. And that’s a shame — because there’s so much more to experience here than just the gut punch of a kick drum. Did you know the low B of a 5-string bass vibrates at 30.9 Hz? Or that the lowest note on a concert piano comes in at 27.5 Hz? And of course, extended sub bass makes bass-heavy genres sound fantastic, too.\u003c\/p\u003e\n\u003cp\u003eAnd that’s the magic trick here. In doubling the sound pressure at the very lowest frequencies, we’ve nevertheless retained extraordinary precision and balance throughout the sub bass, mid-bass, and beyond. Most impressive is how this affects the listening experience. Extension on the low end changes everything — by creating more space for the sound. Against a deeper backdrop, highs feel more brilliant, the soundstage deeper, emotions stronger.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"Sennheiser HD 660s2 Extended Subbass\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/hd660s2-2.png?v=1692028206\"\u003e\u003c\/p\u003e\n\u003ch3\u003eThey feel as great as they sound\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eComfy slippers, your favorite jeans, the HD 660S2.

They call it that because the frequency response curve is shaped like a bathtub. We like a nice soak as much as the next person, but with bathtub sound you're drowning in bass and treble, vocals are weak, and certain frequencies resonate too loudly.\u003c\/p\u003e\n\u003cp\u003eThe HD 550 is the opposite - no gaps, peaks, or loofahs here. That means instruments don't get \"lost in the mix\". You can hear everything, and clearly. Deep sub bass reproduces frequencies you feel more than hear. Treble extends far beyond human hearing. Then there's \"soundstage\". Basically, high-end headphones make it feel like each sound is coming from a specific location. Not just left, right, or center, but also near and far, in front or behind you. Your ears do this 3D thing in real life, too. And with the right headphones, it works with recordings, games, and soundtracks.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"https_3A_2F_2Feu-central-1-akqa\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/https_3A_2F_2Feu-central-1-akqa.graphassets_2.png?v=1745596911\"\u003e\u003c\/p\u003e\n\u003ch3\u003eWhat acoustic sorcery is this?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eGetting a headphone design just right is a balancing act. It helps if you've been on this tightrope before.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMany modern headphones rely on electronics to achieve the desired sound. The HD 550, however, will have none of this: you get a direct analog signal path from source to ear. That means pure, unadulterated sound without additional noise or artifacts. This did put our engineers on the spot though: it meant the headphones had to be acoustically flawless.\u003c\/p\u003e\n\u003cp\u003eThey started with our excellent 150-ohm transducer inside the proven HD 500 chassis. We manufacture the transducer ourselves in Ireland, by the way, so you get outstanding quality and perfect channel matching. To create that 3D sound and wide soundstage, the transducers angle back towards the ears, mimicking real-life hearing. The dust cover is acoustically transparent. Even the ear cushion materials were selected for their acoustic properties. And a strategic bit of foam ensures smooth treble integration and controlled bass. The result is a neutral balance even our most demanding fans will appreciate. Open and airy, but never harsh, the HD 550 headphones are smooth enough to be anyone's daily driver.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"https_3A_2F_2Feu-central-1-akqa\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/https_3A_2F_2Feu-central-1-akqa.graphassets_3.png?v=1745596922\"\u003e\u003c\/p\u003e\n\u003ch3\u003eSo light and comfortable they practically disappear\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHas there been a contest for \"most performance per gram\"?

And you said, \"make it light, make it comfy, and make it sound great.\" So we revised the headband, using high-quality synthetic leather and softer foam. With such a low total weight, less clamping force was required. Which in turn allowed us to use soft, comfy earpads with plush velour. You get a fit that's stable but so unobtrusive that even long sessions are no problem. Work, play games, or listen for as long as you like - without pinching, pressure, charging, or pairing.\u003c\/p\u003e\n\u003ch3\u003eBut will they outlast my favorite band?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDepends who your favorite band is!

Simple - German engineering and quality materials. And those haven't changed. From the mechanics to the steel covers, our headphones are designed to withstand daily use or give collectors something to take out of a cabinet and dust every month for decades. You can get replacement parts like earpads for these headphones and many other Sennheiser products now - and years from now. And of course, all the accessories from our HD 500 range are compatible with your new HD 550 headphones.\u003c\/p\u003e\n\u003ch3\u003eDiving deep into the tech specs\u003c\/h3\u003e\n\u003cp\u003e\u003cimg alt=\"image_4608d8ce-ab77-4798-bd5b-db264382d268\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/image_4608d8ce-ab77-4798-bd5b-db264382d268.png?v=1745596778\"\u003e\u003c\/p\u003e\n\u003cp\u003eHeadphone frequency response graphs look very different from those for loudspeakers, which are ideally very flat. Here you can see a big rise on the right (treble) side and then it falls off a cliff. But this is in fact very close to what's considered ideal for headphones. Because leading manufacturers base their goals on extensive psychoacoustic research about listeners' subjective preferences.\u003c\/p\u003e\n\u003cp\u003eFor instance, it turns out that headphones negate the function of the outer ear, which otherwise amplifies sounds in the 3 kHz region. So, the ideal response for headphones is much higher there. Resonances in the inner ear also make sounds between 7 and 10 kHz louder, which is why the graph dips abruptly around 8-9 kHz. We can see here that the HD 550 builds on the already excellent characteristics of the HD 599, extending even further into subbass territory while still offering strong, analytic mids and brilliant treble without sibilance or harshness. The graph reflects the HD 550's solid, satisfying bass response, balanced midrange, and precise and airy treble.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eArticle number (SKU)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e700455\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCable length\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e1.8 m\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEar coupling\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOver ear\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEar pad material\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSynthetic velour\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency response\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e6 Hz - 39.5 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNominal impedance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e150 Ω\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSound pressure level (SPL)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e106.7 dB \/ 1 V RMS\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTHD, total harmonic distortion\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u0026lt;0.2% (1 kHz \/ 90 dB SPL)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTransducer principle (headphones)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003edynamic, open\u003c\/p\u003e\n\u003ch3\u003eWhat's included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHD 550 open-back headphones\u003c\/li\u003e\n\u003cli\u003e1.80 m cable with 3.5 mm plug\u003c\/li\u003e\n\u003cli\u003e3.5 to 6.35 mm screw-on jack adapter\u003c\/li\u003e\n\u003cli\u003eDrawstring bag\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sennheiser","offers":[{"title":"Default Title","offer_id":48357793399017,"sku":"700455","price":349.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/hd_550_iso_front_final_copy.jpg?v=1762468967"},{"product_id":"sennheiser-hd-500-bam-boom-arm-for-hd-500-series","title":"Sennheiser HD 500 BAM Boom Arm for HD 500 Series and HD 620S","description":"\u003cp\u003eThe microphone seamlessly plugs into the headphone’s cable port to give gamers, audiophiles, and everyday professionals a first-party microphone solution that pairs perfectly with the brand’s hallmark immersive acoustics.

It’s that elusive blend of long-haul performance and all-day comfort that will ensure these become your new favorite daily driver headphones.\u003c\/p\u003e\n\u003ch3\u003eWhy the HDB 630 sounds exquisitely neutral\u003c\/h3\u003e\n\u003cp\u003e\u003cimg alt=\"hdb 630 vs momentum 4\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/hdb_630_vs_momentum_4.png?v=1759933767\"\u003e\u003c\/p\u003e\n\u003cp\u003eThe HDB 630's tuning is all about balance: Fast and extended bass, clear lifelike mids, and controlled treble that keeps the music feeling open and natural.\u003c\/p\u003e\n\u003cp\u003eThe HDB 630's curve compared to the MOMENTUM 4 shows how audiophile tuning changes the listening experience.\u003c\/p\u003e\n\u003cp\u003eNotice the low end: The HDB 630's sub-bass and mid-bass are quick and controlled, staying closer to neutral. This reduces any \"masking\" effects that can hide vocal detail. Moving into the lower mids, the HDB 630 remains smooth and even, keeping voices present and lifelike.\u003c\/p\u003e\n\u003cp\u003eIn the upper mids, there's a tasteful lift that gives vocals a richer, more intimate presence, balanced by a still-neutral bass foundation. The treble region keeps that balance, adding a sense of air without harshness - something you can see in the rise before 10 kHz, which helps improve the perception of a natural, open space around instruments.\u003c\/p\u003e\n\u003cp\u003eThe result is a frequency response tuned for speed and clarity in the bass, lifelike mids, and controlled treble - all without the peaks or dips that can cause listening fatigue. It's a more neutral, refined take on Sennheiser's wireless sound that makes long sessions and critical listening a unique pleasure.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eArticle number (SKU) 700445\u003c\/li\u003e\n\u003cli\u003eWeight 311 g without cable\u003c\/li\u003e\n\u003cli\u003eAudio cable 1.20 m cable with 3.5 mm plug, detachable, right side\u003c\/li\u003e\n\u003cli\u003eUSB cable 1.20 m with C-to-C connection\u003c\/li\u003e\n\u003cli\u003eEar coupling Over-ear\u003c\/li\u003e\n\u003cli\u003eEar pad material Leatherette (synthetic)\u003c\/li\u003e\n\u003cli\u003eResolution Up to 24 bit \/ 96 kHz with USB-C, analog input or BTD 700 Bluetooth® USB C Dongle\u003c\/li\u003e\n\u003cli\u003eConnectivity Bluetooth 5.2\u003c\/li\u003e\n\u003cli\u003eCodec support aptX™ Adaptive™, aptX™ HD, aptX™, AAC, SBC\u003c\/li\u003e\n\u003cli\u003eFrequency response USB: 6 Hz - 40 kHz (only when using Line-In, USB (96 kHz) or Bluetooth with aptX adaptive (96kHz), 6 Hz - 22 kHz (otherwise)\u003c\/li\u003e\n\u003cli\u003eNominal impedance Active 480 Ω\u003c\/li\u003e\n\u003cli\u003eSound pressure level (SPL) 105 dB (1 kHz \/ 0 dBFS)\u003c\/li\u003e\n\u003cli\u003eTHD, total harmonic distortion \u0026lt;0.2 % (1 kHz \/ 100 dB SPL)\u003c\/li\u003e\n\u003cli\u003eAcoustic design Closed-back\u003c\/li\u003e\n\u003cli\u003eTransducer Electrodynamic (moving coil)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHDB 630 closed-back headphones\u003c\/li\u003e\n\u003cli\u003eBTD 700 Bluetooth® USB C dongle\u003c\/li\u003e\n\u003cli\u003e1.20 m USB C-C audio and charging cable\u003c\/li\u003e\n\u003cli\u003e1.20 m audio cable with 3.5 mm plug\u003c\/li\u003e\n\u003cli\u003eIn-flight adapter\u003c\/li\u003e\n\u003cli\u003eCarrying case\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sennheiser","offers":[{"title":"Default Title","offer_id":49188181934313,"sku":"700445","price":499.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/hdb_630_isofront_finalcopy.jpg?v=1759934625"},{"product_id":"sennheiser-hd-400u-headphones","title":"Sennheiser HD 400U Over Ear Headphones","description":"\u003ch2\u003eLightweight, foldable headphones\u003c\/h2\u003e\n\u003cp\u003eThe HD 400 Series features a one-button smart remote, which allows you to control music and take calls with ease, and the sturdy folding design makes these headphones durable and compact enough to be taken anywhere.\u003c\/p\u003e\n\u003ch2\u003eFor a unique listening experience\u003c\/h2\u003e\n\u003cp\u003eSennheiser’s dynamic drivers deliver a well-extended sound response with dynamic bass for a unique listening experience and closed-back around-ear headphones reduce unwanted background noise for your comfort.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTransducer principle dynamic, closed-back\u003c\/li\u003e\n\u003cli\u003eWearing style Over-Ear\u003c\/li\u003e\n\u003cli\u003eAcoustic principle closed\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCable length 1.4m\u003c\/li\u003e\n\u003cli\u003eWeight 217g\u003c\/li\u003e\n\u003cli\u003eFrequency response (speaker) 18 Hz to 20,000 Hz\u003c\/li\u003e\n\u003cli\u003eImpedance 18 Ω\u003c\/li\u003e\n\u003cli\u003eTransducer size 9.7 mm\u003c\/li\u003e\n\u003cli\u003eTotal harmonic distortion (THD) \u0026lt; 0.5% (1 kHz, 100dB)\u003c\/li\u003e\n\u003cli\u003eFrequency response (microphone) 100 to 10,000 Hz\u003c\/li\u003e\n\u003cli\u003eMicrophone pick-up pattern Omni-directional\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhat's included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHD 400U around-ear headphones\u003c\/li\u003e\n\u003cli\u003eRCU 400 Detachable single-sided cable with 1-button remote and USB-C Plug\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sennheiser","offers":[{"title":"Default Title","offer_id":50567415365865,"sku":"800126","price":99.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/Image8_19b53ecb-0db5-4bfb-8ef9-e89641513f5e.jpg?v=1772485553"}],"url":"https:\/\/audio46.mom\/collections\/sennheiser-hd-series.oembed","provider":"Audio46 Headphone Store","version":"1.0","type":"link"}
