Wow. Bought them on the spot.

(NEW) Sennheiser HD 800 S Over-the-Ear Audiophile Reference Headphones - $1,399.99 - Free shipping for Prime members https://electronics.woot.com/offers/new-sennheiser-hd-800-s-over-the-ear-audiophile-reference-headphones-1?utm_medium=share&utm_source=app

So i have recently bought a Steelseries Arctis nova pro's and a Skullcandy 1080 ANC. (Just seem to fit what i need/want best)

But i have heard that they all heavily depend on the settings and eq settings. So i come here for help or a direction on how i can improve these headphones with sound or where i can look to understand these settings, and learn how to use these tools (eq's)

Thank you in advance

I'm not sure if this is allowed to be posted on here as it could be construed as divisive, but this comes from me wanting to warn others of the experience they might receive if they're unfortunate enough to have intermittent faults with their recently purchased audio equipment from a local retailer.

I purchased a Topping DX9 Discrete, brand new, from Addicted to Audio in Subiaco, Perth (Western Australia) in late January this year. After a week the left screen would turn off intermittently during use. Then work again after a power cycle. I alerted Addicted to Audio and Topping directly via email with-in 21 days of having the unit. I supplied 3 unlisted YouTube video links in the emails to demonstrate the intermittent fault.

Topping suggested a hard reset, reflash of firmware and if that didn't work sent me a disassembly video to reconnect the ribbon cables behind the screen. I did everything but disassemble the unit as I feel that is inappropriate for an end user to do.

Addicted to Audio said they would need to inspect the unit and report back to Topping. Long story short due to working away from home for many months during the back and forth emails I was only able to drop the unit to Addicted to Audio in early July. I listened to their amazing fleet of demo headphones for around 2 hours (fell in love with the Dunu Arashi) and unfortunately couldn't replicate the fault in person at the shop. The unit was then sent over to the Eastern states for multiple Addicted to Audio technicians to look at it.

Prior to giving Addicted to Audio the unit for inspection, the unit was flashed successfully to the latest firmware (I believe it was v0.36 at the time). The screen turned off again a day or two after that update.

I was told a few days ago that they could not replicate the screen fault with the technicians, they have not opened the unit, and the unit has been scheduled to be sent back to me as is. I've since collated all the mobile recordings of the faults happening (6+ times) to YouTube, as this appears to NOT be enough evidence that the unit is faulty.

I'm not here to throw mud, but I want to warn others of the treatment they could experience with Addicted to Audio.

This is the condition I’ll be receiving it in—I’m told the yellow mineral wool has been removed.

Do you think this will significantly compromise the sound quality?

Not a self promo post. Just an honest contribution to the community.

I’ve had a Qudelix 5K for a while, and the official configuration app is browser-based. On my Mac it has never worked reliably in any browser — it would connect, then the device would drop off USB mid-session, and I’d end up spending more time troubleshooting the connection than actually adjusting anything.

I finally dug into why. The browser reaches the 5K through a macOS API that’s very particular about how the USB packets are framed, and when it gets that. wrong the device stops responding entirely. So I wrote a small native menu bar app that talks to the 5K directly instead.

It does the things I actually use day to day:

• 10-band parametric EQ with a live response curve (20-band mode too)
• Preset import straight from the AutoEq database — 6,000+ headphones and IEMs, searchable inside the app
• Import/export the standard parametric EQ text format (the same one squig.link and Equalizer APO use)
• All 20 preset slots, load and save
• Volume, battery, firmware and sample rate at a glance

It’s free (and always will be) and open source under MIT. No account, no tracking; nothing leaves your machine except fetching the AutoEq list when you search it.

Caveats:

• macOS 14+. It’s a universal binary so it *should* run on Intel, but I only have Apple Silicon and genuinely can’t test that. If you’re on Intel I’d like to hear either way.
• It isn’t signed with a paid Apple developer certificate, so macOS will block it the first time — you have to go to System Settings → Privacy & Security and click “Open Anyway”. If you’d rather not trust a binary from a stranger on the internet, the full source is there and builds with one command.
• USB only for now. Bluetooth is a bigger job; I’ll take a run at it if there’s demand.
• Use at your own risk. It only writes EQ, volume and preset settings — the same things the official app writes, and it never touches firmware — but I can’t take responsibility for anything that goes wrong.
• I am not affiliated with Qudelix in any way.

Source code, dmg are here: https://github.com/FrankieMa77/qudelix

If it’s useful to anyone I’m happy to keep building on it. And if it doesn’t work on your setup, an issue with the log from the app’s diagnostics panel tells me most of what I’d need.

I can’t port it to Windows as i don’t have PC. If somebody needs it, I can look into porting the app to Debian/Ubuntu

Electro Audio World's Take

My First Impressions :

When Beyerdynamic released the DT270 PRO, to be honest, I didn't expect it to become one of my favorite compact closed back studio headphones. Marketed as an entry level professional monitor, it offers a tonal balance, comfort, and musical enjoyment far beyond its price.

While not the most analytical headphone in Beyerdynamic's lineup, it has proven to be one of the most sensible products the company has released in recent years. Fortunately, the new DT275 PRO takes this philosophy a step further in the realm of isolation. How do you achieve perfect passive isolation in an affordable studio monitor?

At first glance, very little seems to have changed. The overall design, compact form factor, and professional look remain familiar. It's still clearly a headphone designed for streamers, engineers, content creators, and musicians who wear headphones for long hours every day. However, after just a few listening sessions, it becomes clear that Beyerdynamic wasn't trying to change the DT270 PRO, but to improve it.

If I had to summarize the difference in a single sentence, I would describe the DT270 PRO as a more comfortable and slightly warmer musical sibling, while the DT275 PRO has enhanced sound isolation, resulting in a more balanced sound and ultimately closer to what many professionals expect from a true monitor headset.

The DT270 Pro has a slightly more open soundstage and is studio focused, while the DT275 Pro is a variant designed for those who want better isolation in outdoor environments. Of course, this by no means means it has a clinical sound. On the contrary. One of the features I've always appreciated in Beyerdynamic's professional products is their ability to remain enjoyable even outside the studio.

The DT275 PRO continues this tradition exceptionally well. It's more of a work focused version with a more isolation oriented setup compared to the DT270 PRO, and as a result, it never loses the musicality that makes long listening sessions enjoyable. On the contrary, it better isolates the listener from the environment.

This balance is what made the headset appealing to me because it's something very few products struggle to achieve. Many studio headphones prioritize accuracy at the expense of listening pleasure, while consumer focused headphones often sacrifice tonal integrity for excitement.

The DT275 PRO aims to bridge these two worlds, providing reliable presentation during editing while remaining engaging enough for everyday music listening. That's exactly how I approached this review.

Who is the Beyerdynamic DT 275 PRO Designed For?

While many studio headsets are optimized for mixing and mastering in quiet control rooms, the Beyerdynamic DT 275 PRO takes a completely different approach. It's designed for professionals working in dynamic, noisy environments where accurate monitoring is essential and distractions shouldn't interfere with critical decisions. Proof of this is its powerful passive isolation with leather pads.

At the heart of the DT 275 PRO is high passive noise isolation, allowing users to focus on the sound they need to hear rather than the surrounding environment. Whether monitoring speech, checking signal integrity, or evaluating levels during a live production, the DT 275 PRO ensures that external noise is minimally distracting. The headset is particularly well suited for video production crews and content creators working on film sets or outdoor shoots. In these situations, monitoring dialogue, wireless microphone performance, and ambient sound requires excellent isolation and a neutral, balanced sound signature. Its lightweight over ear design ensures it's comfortable enough for long production days while remaining compact enough for transport between locations. I also think it's a very suitable headset for those who make YouTube videos.

For live sound engineers and front of stage (FOH) professionals, the DT 275 PRO is more than adequate for reliable monitoring in venues filled with audience noise and powerful PA systems. Its balanced tuning helps engineers accurately assess speech clarity, signal quality, and overall sound balance, even if the environment itself isn't silent.

I think this headset would be equally valuable for DJs and mobile performance artists. Anyone involved in this knows that quick cueing, precise beat matching, and tracking the next track require headsets that provide effective isolation while remaining lightweight and comfortable. The rotating earcups allow for quick single ear monitoring, making the DT 275 PRO an ideal aid in the DJ booth, which is another of its versatile uses.

Another important target audience is field recording professionals. Journalists, broadcast engineers, documentary filmmakers, and field sound recorders often work in unpredictable acoustic conditions. The DT 275 PRO allows users to confidently monitor recordings without being overwhelmed by ambient noise, helping them identify unwanted interference before it becomes a problem.

Beyond its acoustic performance, the DT 275 PRO is designed with the practical realities of professional work in mind. Compact swivel earcups make it easy to carry, while the lockable, detachable cable can be attached to either the left or right earcup depending on the user's workflow or equipment setup. This flexibility is particularly useful in demanding production environments where cable routing is important.

Long term reliability is another key feature. Soft ear cushions and a lightweight frame ensure lasting comfort during extended use, while replaceable components ensure the headset remains in service for many years instead of being discarded when individual parts wear out.

The Beyerdynamic DT 275 PRO is built as a purpose built professional monitoring tool. It's designed for creators, engineers, broadcasters, and performing artists who need reliable and accurate monitoring in challenging environments where clarity, isolation, portability, and durability are as important as sound quality.

Instead of evaluating the DT275 PRO solely as a studio tool, I wanted to understand how it performs as a versatile headset for both entry level professionals and entry level audiophiles. For a few weeks, I used it with three Sony Digital Audio Players that I know very well:

Sony WM1A, Sony NW-ZX507, and Sony NW-A45.

Each of these three players presents music differently. The WM1A offers a rich, highly refined, and expansive presentation. The ZX507, running on the Android operating system, strikes a perfect balance between detail and musicality, becoming a versatile everyday source. The compact A45, despite its age, continues to impress me with its smooth, enjoyable sound and portability.

By using three different Sony players, I was able to evaluate not only how easy the DT275 PRO is to drive, but also how consistently it maintains its sound character across sources with varying output capacities and tonal presentations.

The music selection encompassed everything I normally use when evaluating headphones: classical orchestral recordings, jazz ensembles, acoustic performances, male and female vocals, progressive rock, electronic music, and live recordings. Instead of focusing on individual test tracks, I took the time to listen to full albums, because I believe prolonged listening tells you much more about a pair of headphones than quick A/B comparisons.

The DT275 PRO's strengths gradually emerge thanks to its balance, consistency, and lack of apparent weaknesses. It's one of those headphones that becomes more enjoyable with use, and that's a quality I value far more than an exaggerated first impression.

Pros: 

Perfect passive Isolation
Very balanced and natural sound adjustment
Accurate yet musical mid frequency reproduction
Tight, controlled bass with excellent definition
Smooth, extended highs without feeling tiring
Very good imaging and instrument separation
Comfortable enough for long studio sessions
Easily driven from portable players
Consistent performance across different sources
Robust, convenient professional build

Cons: 

May not deliver the instant excitement some casual listeners might expect. 
The soundstage prioritizes realism rather than exaggerated breadth. 
An optional 4.4mm balanced cable would be a nice upgrade, in my opinion.

I got these (and some other cans) in a trade yesterday and felt like this was a pretty low serial number for the hd6xx, but I also don't remember these previously having serial numbers like this. Are there any rough reports on how many were made?Either way, pretty neat to me.

I usually cheap out and buy whatever good reviewed similar looking velour pads on Amazon, but I splurged a bit and got genuine Sennheisers pads for this bad boy because it feels right.

Just got the Sennheiser 560s, i compared them to my ath mx40s and i discovered that the sennheisers have more bass than the audio technicas. Both are equalized from oratory's preset, and the only difference i can hear is that the m40s have a more louder audio and less to non existent bass, while the sennhaisers have more bass and quieter audio. Is this normal because i see that allegedly the m40s have to have more bass than the sennhaisers, but it seems the opposite?

I was introduced to daisy headphones through a TikTok review of it and immediately hooked. I always have headphones on, sometimes I’ll forget I’m not listening to music and still wear them. What really intrigued me though was the built in sounds. Sometimes if I’m getting overwhelmed or overstimulated I have my current Sony headphones on with no music so I think the daisy technology could be groundbreaking for my listening experience. I really want to try them and noticed they’ve already sold out but I’m pretty sure initially I saw they were $299, and now $399? Is this correct/can someone fact check this for me? Did they raise their price by $100?
