 Google the best studio headphones for the last few years and it won't be unusual for you to find the Bayer Dynamic DT770 Pros amongst the contenders. People like their sound, build quality and comfort but there are some newer kids on the block. Let's take a look. Hi folks I'm Mike and I hope you well. If you're looking for studio headphones then I reckon the DT770 Pros from Bayer Dynamic should definitely be on your shortlist but how do they compare to the newer DT700 Pro X's also from Bayer Dynamic. Well I've been testing them out in three important areas build and design, comfort and of course sound. Now if you want to buy either of these pairs of headphones check the links in the description down below but do hear me out first. Let's get started by taking a look at build and design. Both of these headphones are closed back which means they can be used for mixing but excel during the recording or tracking process. They're both built well using hard plastic for the ear cups, metal hinges with a simple robust design, a cushion headband and those rather iconic Gravelore ear pads. They are similar in size however the older DT770 Pros are a little lighter weighing in at 270 grams whilst the newer DT700 Pro X's weigh 350 grams. Both have replaceable headband cushions and ear pads and it's with the ear pads where we find the big point of difference. The outer diameter of the new 700's is noticeably smaller however the inner diameter is pretty similar so they should accommodate similar ear sizes. However the new 700's have a much thicker ear pad and I'm not exactly sure why but for me this resulted in a better fit to the head which in turn noticeably improved isolation seemingly without the need for extra pressure. Now as much as the older 770's have been loved people have not always loved the attached coiled cable it can feel heavy and I always find them difficult to manage during recording. This has all been fixed with the new 700 Pro X's which sport detachable cables via a mini XLR connection. Interestingly in the box you get two straight cables a 1.8 and a 3 meter but for those of you who do love coiled cables these are available from the Bayer Dynamics website. So aesthetically and functionally there's been some interesting changes but how does that translate into comfort? Comfort is so incredibly important when using headphones in the studio you're going to be using them for many hours and that could even affect the performance of an artist who is using them. Now the DT 770 Pro's have been well known for a long time for being very comfortable headphones it's one reason why people buy them and it's certainly a reason why they continue to use them. Now although they are noticeably lighter than the new DT 700 Pro X's I reckon the new guys have the slight edge in terms of comfort. Why? I think firstly because you don't have that heavy coiled cable hanging down and sort of weighing you down and secondly I think the new design of the ear pads really helps with comfort and it seems to affect the amount of pressure which is required for the headphones to maintain their excellent isolation attributes. So I think it's a little bit of a win here for the DT 700 Pro X's however both of these headphones are very comfortable headphones but that is no use unless the sound is right. The DT 700 Pro X's have the completely new Stellar 45 drivers. Now both headphones start their frequency response from 5 Hertz but the new 700's extend the upper end from 35 to 40 kilohertz. With both headphones we see a pretty flat response from around about 200 Hertz to 2 kilohertz and both have a noticeable lift at 10 kilohertz. Remember no headphones have a completely flat response so you still need to learn the strengths and weaknesses of yours for mixing. These response graphs suggest that the new 700's have a little bit more oomph on the lower end however graphs are one thing and experience is another. So the rest of what I'm about to say is far more subjective and I want you to keep a couple of things in mind. The size and shape of your head and the way that those headphones fit it can affect the sound of headphones. Also I have been using the DT 770 250 ohm versions whereas all of the new DT 700 Pro X's are 48 ohms and there can be slight differences when headphones have different impedances. But with all of that said here's what I felt with the differences subjectively when I listened to these. First of all with the new DT 700 Pro X's I definitely felt more oomph in the low end. I shouldn't probably say oomph because I don't want to say that they're sort of hyped in that area. Now that's not true at all but it is just a fact I think that the DT 770 Pro's were a little lacking in that area. I never felt that I've been able to trust the low end of a mix with these. I felt that it was much much better with the DT 700 Pro X's. I also found with these headphones that there was a little bit lacking you might say or a little bit more subdued in some areas of the high end specifically at around about five kilohertz. Now I tested and tested and tested again isolating those frequencies. That's definitely what I was hearing. Now that does defy the graphs that we looked at earlier but as I say your experience can be a little bit different to the graphs. Either way these are excellent headphones in terms of sound but I'm going to give a nod to the newer ones just a little bit in terms of accuracy especially in the lower end. So before we get into my conclusion let's talk about price. Now do check the links in the description down below for the current prices. However at the time of making this video on Sweetwater the DT 770 Pro's are $159 whereas the newer DT 700 Pro X's are $279. Now that's a solid 75% increase so if budget is an issue for you then definitely go for the DT 770 Pro's. They are tried and tested, they're reliable, they're comfortable and you can do a pretty decent mix on them once you get to know them, once you learn where their good points and their slightly less good points are. However overall I definitely think the DT 700 Pro X's are a better headphone. Firstly they've improved that design of the cups. That seems to mean that they need less pressure on your head to achieve what are really excellent isolation properties. They seem to leak a little less than the DT 770's did and they were already pretty good. The next thing is that cable. Thank you Bayer Dynamic for fixing the cabling issues of these headphones. It's great that they're detachable, it means you can swap them out for the kind of cables that you prefer whether that be straight cables or curly cables. Now finally I do think the sound is a little bit more accurate. As you heard me say earlier especially in the low end I think I'm going to be able to trust these ones a little bit more so overall they are the better headphone. Now if you are a loyal and experienced user with these old DT 770 Pro's but it's time for a change perhaps your old ones have worn out and you're thinking about replacing then I think you'll be really pleased with these new DT 700's because they sort of have all the good things of this these headphones without the sort of bad things. They've improved things definitely so if that's you then I'd spend a few more pennies go for these ones.
