So, Jacob 1 and Jacob 2, why do you enjoy Prime Day? In unison: 'Because our fav Sennheiser headphones are 30% off or more.' Thanks, Jacobs

Sennheiser's HD 599 headphones are some of the best budget audiophile headphones on the market, offering a signature V-shaped sound profile with punchy bass and sharp highs. It's open-backed, too, for a more natural sound. At this price, it's a great entry point into audiophile territory.

Price check: Newegg $168.88

Diving into the world of excellent high-end audio doesn't need to cost an arm and a leg, as this pair of HD 6XX headphones proves. It's basically the exact same pair of headphones as the HD 650 I use daily except much, much more affordable. They sound fantastic and are a great way to kick off a headphone collection or as a lasting upgrade for your audio.

If you want your new headphones to shine, you'll be needing a quality DAC and amp to power them. This tube amp not only looks excellent, thanks to those four tubes (two each for preamp and power amp phases), but it also delivers a silky and natural tone that highlights the HD 650 (or HD 6XX) sound extremely well. Just note, you'll also want some access to high quality audio files to take full advantage. I use Tidal, as it's recently had a big price drop and offers full FLAC, though there are many others worth checking out.

It's rare that two Jacobs find their way into the same office, rarer yet that both have a passion for the same brand of headphones, and rarer than the rarest of rares that both of their favorite respective headphones should have hefty discounts for Prime Day 2024. What incredible times we live in when just such an occurrence has, well, occurred.

Both of us (Jacob and Jacob) love our Sennheiser headsets. Senior boss-man Jacob Ridley has the senior boss-man headphones, the Sennheiser HD 650—Jacob R's note: the HD 800 S are the boss-man headphones, let's be honest—which we reckon is the best pair of mid-range audiophile headphones for gaming on the market. Junior Jacob Fox, on the other hand, has the entry-level pair, the HD 599.

Both headsets are on sale with 30% or higher discounts this Prime Day. The HD 650 is on sale for $350 at Amazon and the HD 599 is on sale for $130 also at Amazon. There's also the Massdrop x Sennheiser HD 6XX on offer for $169 at Drop (save $50), which Jacob Ridley reckons is almost identical to the HD 650 but cheaper. Plenty for mid-range or enthusiast audiophiles to sink their teeth into for a relatively low cost, then. Let's hear what the Jacobs make of them.

Jacob F's HD 599 headphones

Jacob F: My HD 599s have been sitting on my head day-in, day-out, for a very long time. They're old as can be, but in the world of audiophile headphones this matters practically zero. Great headphones are great headphones, full-stop. 

Sure, they don't have any of this new planar driver wizardry, but the dynamic drivers in the HD 599's cans sound incredibly natural and plenty punchy. Dynamic vs planar is a subjective choice anyway—both have their pros and cons. 

It's hard to convey headphone sound profiles in words, but the HD 599's drivers aren't completely neutral. They accentuate mid-bass frequencies a bit, as well as the high-end, which is somewhat of a staple for Sennheiser cans. They sound simply wonderful to my ears, at least.

For open-backed headphones that offer a stellar soundscape, they're what I'd recommend to anyone in the sub-$150 price range, as I would for anyone looking to switch over from standard gaming headsets to audiophile headphones. I should also mention that they're comfy enough that, after all this time, I tend to wear them out of habit while I'm at my desk even when I'm not listening to anything. With this $70 Prime Day discount I can, and will, recommend them in a heartbeat..

Now, Jacob Senior, tell me about your HD 650 headphones.

Jacob R's HD 650 headphones

Jacob R: The sound of drum and bass erupting down your ear holes. This, my friends, is the HD 650 experience that I enjoy every day. A simple pair of headphones—you'll find no microphone, onboard controls, or wireless connectivity here—and yet my all-together favorite pair for day-to-day use. I don a pair of SteelSeries Arctis Pro Wireless headphones for chatting with mates over Discord but for everything else, it's the Sennheiser HD 650 I'm reaching for.

These headphones offer a clarity I'm yet to find in any reasonably affordable gaming headset. That's not a massive criticism of gaming headsets as much as it is a compliment to the HD 650. The open-back design paired with Sennheiser's upper-range focus deliver fantastic audio quality. While listening to high quality FLACs on Tidal I can revel in parts of the track that you can often miss with more muddled drivers—the trailing high notes or lasting sibilance in a cymbal crash.

With a pair of Sennheiser HD 650, you are also on the hook for a quality DAC and amp combo. I have the Schiit Magni and Modi combo, a classic pairing, though I've recently reviewed the Drop + Xduoo TA-84 OTL and found it to be a handy two-in-one solution that looks pretty slick in all black with four tubes atop.

Speaking of Drop, here's the thing: I wouldn't buy the HD 650 right now. I'd buy the Drop HD 6XX instead. These are almost identical to the HD 650, sound profile and all, and they're usually a lot cheaper at $219. Right now, however, you can scoop a pair for $169.

The Drop + Xduoo TA-84 OTL is also on offer right now at $299. That means you can get the same setup as me (near-enough) for $468.

Jacob got his hands on a gaming PC for the first time when he was about 12 years old. He swiftly realised the local PC repair store had ripped him off with his build and vowed never to let another soul build his rig again. With this vow, Jacob the hardware junkie was born. Since then, Jacob's led a double-life as part-hardware geek, part-philosophy nerd, first working as a Hardware Writer for PCGamesN in 2020, then working towards a PhD in Philosophy for a few years (result pending a patiently awaited viva exam) while freelancing on the side for sites such as TechRadar, Pocket-lint, and yours truly, PC Gamer. Eventually, he gave up the ruthless mercenary life to join the world's #1 PC Gaming site full-time. It's definitely not an ego thing, he assures us.
