Sennheiser Announces the HD 505 Headphones
The Sennheiser brand today announces the HD 505, a headphone crafted for listeners looking to elevate their love for audio to the next level of performance. With its blend of analytical tuning, precise detail, and enduring comfort, the HD 505 brings the essential Sennheiser experience to listening setups and gaming rigs of all kinds.
"The HD 505 is for anyone ready to experience the audio awakening a great set of Sennheiser headphones is known for," said Klaus Hanselmann, Sennheiser Audiophile Product Manager. "There is something truly special in here that puts serious listening within arm's reach of the emerging audiophile or gamer."Your Introduction to True Sound
At the heart of the Sennheiser HD 505 is a custom 120-ohm transducer situated in an open earcup, produced at their cutting-edge audiophile factory in Tullamore, Ireland. With a frequency response stretching from 12 to 38,500 Hz and total harmonic distortion measurement of less than 0.2%, listeners can ensure that their music is reproduced with surprisingly rich detail and integrity. This combination delivers a politely balanced sound signature, with the punchy bass, effortless mids, and non-fatiguing treble the audiophile brand is lauded for. The angled transducers replicate the triangular positioning of a set of nearfield loudspeakers, resulting in an expansive soundstage that enables listeners to sit in the front row of their favorite music, movies, and games.
Timeless Design, Built to Last
The HD 505 is built upon the trusted HD 500 series chassis, celebrated for its long-term comfort and lightweight fit. From the synthetic leather headband to the metal mesh earcup covers, every component is designed to last while exuding an understated sophistication. At just 237 grams, the HD 505 offers a level of comfort that makes extended listening a pleasure. It comes with a detachable 1.8 m (6 foot) cable, with a 3.5 mm (1/8-inch) plug and 6.3 mm adapter for connection to the widest range of audio sources like amplifiers, sound cards, audio interfaces, and A/V receivers. Like virtually all 500 series headphones, a wide range of cables and earpads—ranging in length, application, and plug type—can be swapped by the user without tools. This modular design lets the HD 505 adapt to the wearer's evolving setup over time such as incorporating a balanced audio source or adding an in-line microphone

The HD 505 will be available starting today from Amazon.com with an MSRP of 279,90 EUR / 249.95 USD.

14 Comments on Sennheiser Announces the HD 505 Headphones
That being said, I am curious to see the reviews. I consider the 500 series chassis to be the most comfortable headphone ever created and having another option there is never bad.
Even without hearing this, I just know a mid-range dynamic is going to struggle against innovative planar design.
Also, the whole 500-family isn't really Sennheiser any more, right? They sold out to these guys: www.sonova.com/en/sennheiser
Are they just using the brand name and IP or are these still made by the same people in the same location as they used to be before selling off the business?
That said, why do you want to replace the HD580? They haven't been replaced by anything and in fact the HD6xx (pretty much the same headphone) is still being recommended today and for good reason. You can get replacement parts like earpads pretty easily too.
If I was replacing the Precision 580's with something as close to like-for-like as possible, what is the equivalent model in the HD6xx family?
Honestly, still completely happy with HD58X, so I probably will put that craving to upgrade away again. I almost upgraded to some Ananda Stealth's, but I backed out at the last second.
This is a good post with measurements of HD580 vs HD58X and HD6XX
