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 HD 599 | Open-back | 12-38,500 Hz | Wired | $199.95 $129.95 at Amazon
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

Massdrop x Sennheiser HD 6XX | Open-back | 10 Hz – 41 kHz | Wired | $219 $169 at Drop (save $50)
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.

Massrop + Xduoo TA-84 OTL | Tube amp + DAC | $399 $299 at Drop (save $100)
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
