What is the ACTUAL difference between the DT770, DT880 and DT990 Beyerdynamic headphones?

If you fancy buying some of our modified beyerdynamic headphones check out the link below

It is the question nobody asked but should have ;)
The Beyerdynamic 770, 880 and 990 all share the same driver design but have totally different sound signatures. Now... I know there are many versions of each of these headphones with impedances ranging from 32ohm to 600ohm which all sound different but in this video we will look at how they have tuned the sound of the driver an enclosure. It is quite interesting to see the differences and the techniques they have used to tune them

yeah i dig these breakdown videos cuz no one else makes the effort to take them apart and show the components and engineering behind the sound. good stuff!

Thanks for this breakdown (hopefully not literally). The 880 Edition may be designed after these 770 and 990s, but from what I understand looking at their old catalogs the 880 was the original of the lineup (early 80s, I had a pdf catalog from 1984 which shows a DT 880 Studio, DT 880 Monitor and regular DT 880 edition. They had lesser models too like DT 660, 550, 330, 220). The 990s came out later in the 80s as the last of the three, meaning to be the ultimate. Of course these models have been further tuned and redesigned over the years since then, so one made today probably does not sound the same as a new old stock (NOS) from the 80s or 90s. They also used to sell one in the early 90s called the DT 911.

These days they sell something called the TYGR 300 R for gamers, which is a modified 990 that has different filter pads inside it. I think the same kind used in the Amiron, so the highs are less harsh.

i have both 990 and 880. i bought the 880 first. a week later i bought the 990. they are definitely different. i would choose the 880 for anything that didn’t require a bass involvement like electronic music. the 990 gave the bass (extra), but the 880 gave a nicely sweet mids and highs. comfort is unbeatable

Hey man, i just want you to know that this is an amazing and informative comparison. Thank you and to more subs! cheers!

Well done! I find it fascinating how headphone manufacturers sell us the same product, with a variety of creative tweaks. You have taken this beyond where others have gone.

Great video. Never seen any of your videos but the way you presented the facts and got straight to the topic of the video was incredible. I gave you a like and subscribe just for that. Keep up the hard work.

Thank you very much! great review. short but detailed. maybe not a full comperison because there was no actuall sound testing. but the teardown was absolutely great!

[kieftoker]

Best comparison of these 3 variants, thanks! Will get the 880s for sure!

Love my 990 pro but i would like to see detachable cable on them and that 880 case looks awsome

Dang thanks for this video

After getting some used DT 990s I got replacements from amazon. I still listened to the old pads (The seller said they cleaned it and the pads certainly smelled of some kind of cleaning chemical, so no worries on grossness) so I did have a point of reference on what these should sound like.

When I got the replacements, from Beyer's official store page, they sounded way boomy and different. It wasn't until I watched this vid when you showed the differences between the pads that I realized what happened, I compared the two pads and sure enough; my stock pads had black foam on the inside and my replacement pads had silver foam. I got DT 770 pads when I wanted DT 990s

Edit: It was from a third party amazon seller, not beyer direct, but it was on beyer's page

Liked and subscribed! Great job mate! Keep feeding our curiosity!

Great work! Thanks for going to all that trouble to let us peek inside these sweet cans.

Bought the DT880 600ohms after watching your vid. Thanks for the thorough in-depth view of the headphone inerts.

[OKRAinu]

Nice video! Absolutely worth to watch. Thank you!

[sapinit]

Thanks, great review for my decision process!

[kimholm]

this was great. had already bought the 880 Editions. They arrive in 2 days but I believe I made the right choice. My Audio Tecnica's kill my head and they are so dang hot. Good results mixing with them but excited for comfort.

[BenWidmer]

This is excellent!! Thank you for providing this insight - This is what youtube is all about...for me anyway : )

Subbed/Liked...and headed out to purchase some 880s ...

[AlOne-xgdv]

Clear and interesting. Thank you. 880 are appealing. I own the 770 pro and like them. They just lack some space and openness.

[kahlilmichaelpastoriiescur]

Thanks for the break through....or is it breakdown....or better yet showing the ins and outs of the best selling headphonea out there.

Great video and I appreciate all the technical insight from the teardown. But there are also a couple of additional factors such as application of use and impedance in terms of which hardware to drive the headphones. For example, the 770 - (80 Ohm) seems to be the sweet spot in terms of versatility between studio desk and small devices such as Laptops/Phones/iPads etc.
