beyerdynamic DT-990 Pro 250 Ohm

I bought these, the dt-880 (600ohm) and the hd-650.
And I'll quickly write why I picked the 990's over the others.

Comfort:
The dt-880's were amazing, so comfortable, perfect in my opinion.
While the 990's are really similar, they are tighter on the ears, and I don't like that at all, but they are still quite comfortable.
And the hd-650? They clamp like crazy, I couldn't wear these for over 10 minutes, really uncomfortable.

Sound:
Now this category is objective af, you have been warned.
I used the LP-phone-amp-g103 to drive all of these headphones so there shouldn't be any issues with the amp.
With that out of the way, lets start with the headphones that really disappointed me.
The 880's had a really lackluster low end, you could say non existing, and with basically no bass it was just a clear no for me and I didn't bother any further with them.
The hd-650 sounded like the 990's if someone put an equalizer on them that turned down every frequency past 3khz down 3-6db.
They sounded muddy in my opinion, especially compared to the dt-990's.
With that being said, I love the by some considered sharp highs of the dt-990's, everything sounds crystal clear, not "muddy" or "washed out". I listen to a lot of vocals so that's a must for me. But as I said, it ain't for everybody since some might say the highs are over saturated, and they are, but it sounds nice. It's something I'm looking for in headphones, are you looking for that? If not steer away from these headphones. Cons: they might be too sharp for some and too tiring if used in long sessions. Other cons are the fact that you can really hear if a song is mixed/mastered like shit, you can hear everything. I'm not gonna say sh*t like :"you suddenly hear instruments that you previously didn't hear" if you suddenly heard an instrument that you didn't hear before on decent headphones that's on you. But you definitely hear if someone didn't bother cleaning up the samples he used in his song, and you might need different headphones or speakers to enioy songs that are badly mixed.

price/performance: 10/10, I mean ¤140 for these is a steal, you don't get better audio quality for that price, but you probably gonna need a headphone amp as for almost all 250+ ohm headphones.

I've had quite a few headphones over the years for computer usage (Netflix, Youtube and gaming and of course since this year Zoom calls). When my last pair broke because of poor building quality I just decided I needed a more decent pair. Also I wanted to use them for more quiet bass sessions. I never had a pair that could actually handle the sound of my bass well. So I figured, Studio headphones should do.

And well they do. I use them daily for the computer usage I described earlier. For a while I took them to school which they handled perfectly. They're sturdy with a metal frame but just light enough that long time wearing is still comfortable.

Now that I'm wearing these headphones for 6-8 hours a day I do begin to notice the weight but it is not neccesarely disturbing.
So when talking about the sound quality of these. I can only say one thing: it's amazing! The open back produces a very open and light sound. The lower sounds still comes through very well. Even with the open back sound still sounds emerging. It is also nice to be able to hear yourself talking while wearing them on calls. It pairs perfectly with every device I tried to plug it into. As a result I use them for nearly anything.

As for the durability I cannot say much since I've only had them for about 9 months. But they've fallen of my desk a few times and have been carried in my filled backpack (in the sleeve included). But they hold pretty well in normal envoirments with a normal user.

To summarize: I am in love with these headphones because of the sound quality as well as the building quality and ability carry it with you. They're adjustable and comfortable for daily usage. For the price of 120 euros that's all I could ever wish for.

Rather exciting piece of headphones!
Although they have advertised 250 Ohms impedance you average smartphone can drive them pretty well to painfully strong sound pressure level. The caveat however is that if you pair them with a simple amplifier you will unleash the beast <1KHz. I was pleasantly surprised when I first tried them on my phone, then thrilled on my audio interface Komplete 2, finally the HA4 "KOMPLETED" the circle of audio pleasure. I compared them directly to Custom One Pros, Marshall Major and K-701 all four driven from the same source - Komplete 2 + HA4. I equalised the volume to the best of my perception and the DT 990s wiped the the floor with the competition.

Sound: 5 stars - NO DOUBT ABOUT! (Metal, rock, classical music listener here)
Comfort: 5 stars - Pretty fluffy ear cups. I wear glasses and my deal breaker is that the headphones do not press my ears too hard against the frame of the glasses. I do however fear that during summer the ear cups will be a bit too warm.
Quality: 4 stars - Overall pretty solid BQ. I do not like the way that metal brackets on both sides are attached to the head band (Mechatronics engineer's inner voice says - FLIMSAAY!). Luckily ALL parts can be ordered as spares from beyer when they break. I am also not of fan of the fixed cable... that should've been a detachable 3.5mm jack like many other less expensive headphones. The cable itself is a bit of overkill sized gauge telephone coil. It is massively thick and heavy and absolutely not portable. It's not a big problem for stationary setups but please take in into account for portable intentions - they are not.

They sound great, After applying some EQ (personally), the sound is very clear, you can very easily distinguish between different instruments and i find they will be useful for many applications.

Without EQ they are lacking in low end a little bit however and the ear pads currently are a bit stiff due to them being new, However i know from experience they are going to get softer and more comfortable as i use them.

I wish they were slightly deeper and or having the inside profiled for my ears as they touch the end, the material is soft so they dont feel uncomfortable and when i don't remind myself of it i forget about it.

Love them, for a £110 its a great deal and a good set of headphones
