Razer Tiamat 7.1

There are lots of bad reviews for those, however I must say that after properly calibrating them through an equilizer the muddy, cheap sound becomes much much better. In 7.1 mode for playing music those are absolutely horrendous, however if you use bass redirection and set crossover frequency at about 70hz they become quite nice. And if you use 2.0 mode you will need to play with the equilizer a bit to achieve nice results. Therefore you will need a proper sound card with equilizer settings.. I have been using them with SB Live! 24bit with modded drivers as well as with Asus Xonar U7.
The design is very very good, they are very well built and really comfortable. I can hardly feel them despite their size. Also they are durable with strong meshed cable. The pads are soft and don't cause any sweating. 

Long time user of Tritton Ax pros, have logged over 1500 hours on 2 pairs and love them. I was told these will work with the tritton ax pro amp and they do in 5.1.
 
Bass sounds good especially when sniping you can feel it also you can adjust it to be high treble.
 
Very good sound separation.
 
Beautiful pair of headphones, I can now sound beast people in BF4 they stomp around like dinosaurs. With a different sound than my Trittons maybe it's because it has better noise cancelling it like suctions to your ears and are closed backs.
 
I put these only 2nd to the Trittons for sound quality and consistent separation in competitive and casual play mainly due to the 7.1 not compatible with the mixamp. On PS4
 
The Tiamats I only use for gaming , If I want to listen to music I'll use a stereo headphone I dock no stars for this.

Before you read this, I think you should know that I'm not an audiophile and that English isn't my native language.
 
Let me start this on a positive note.
 
The design of Razer Tiamat 7.1 is very good. Even though the actual headset is big, it looks quite nice. The Razer logos on sides light up making this headset even more beautiful. But because the headset is big and heavy, it's not very comfortable for long periods of time. It just makes me want to put my head down and sleep.
 
But as far as the sound quality goes... It's not even close to earbuds that came with my Sony phone. In 7.1 mode, there is no bass at all but as soon as you switch it to 2.0, the bass eats all the other sounds. It's boomy and muddy. You can't hear anything besides granades and gunshots. In addition to that, all the sounds are muffled and it sounds like you're listening to 64kbps sounds in a big, long tunnel.
 
But that's not it. In 7.1 mode, I could  only heard sounds that were on the right and on the left side of me. I couldn't hear anything behind or in front of me. At first I thought that it's my integraded soundcard's fault. So I decided to buy a new soundcard. Asus Xonar something. I don't remember the full name, but as far as I remember, it wasn't bad.
 
The new soundcard upgraded the sound quality. Tiamat sounded a little bit more clear, but still didn't match the $10 Sony earbuds (Not even talking about the Beats Mixr, the best value beats).
 
I returned Tiamat to the store and took my money. I will never buy a Razer product again.
 
I just don't understand why Razer advertises this headset as the ''World's first true 7.1 headset'' that can produce ''crystal clear sound''.
 
Overall, I give this headset a half of the star for the design and another half for nice packaging.

I picked these up knowing that they wouldn't come close to the quality level of my Sennheiser Momentum headphones, but needing a headset, I figured Razer's flagship would be up to the task. The packaging and control box were very nice, and the speaker pass-through dongle was a great touch. It's also rather comfortable, and the auto-adjusting headband is a pleasure to wear. The microphone stays out of the way, and slides up inside the headphones when not in use That said, though, the good ends there.

In 2.1 stereo mode, the sound is very muffled, with almost no treble to speak of. The bass is muddy, and it really reminds me of the sound you get from PC headsets that cost a quarter of the asking price of the Tiamat. In 7.1 mode, however, this reverses almost completely. Bass is virtually nonexistent even after maxing the "subwoofer" volume, and it turns into a shrill, tinny mess. I did manage to get some bass out of it by using the bass redirection function of my sound card (50Hz seems to be the sweet spot), but even then it was still rather muddy. I tried to use it in a game to see how the positional audio was, but I found myself cringing every time an explosion or some other loud noise happened simply because it was so shrill, and the positional effect was drowned out as a result.

In the end, turning on my sound card's CMSS-3D in headphone mode offered far superior positional audio performance than the Tiamat's 7.1 mode. Lesson learned - You have two ears, and two speakers are far better equipped to handle both quality and surround sound than the multiple drivers inside the Tiamat. With Dolby Headphone or CMSS-3D, a stereo headset offers far better performance.

The good:
- 10 drivers (5 per ear) allow for amazing spatial awareness when watching movies/playing games.
- The cushions on each ear are quite nice and provide a good amount of nose cancelling.
- The mic is retractable for when not in use.
- Allow for surround sound speakers to be hooked up and switched to with the press of a button.
- Can be switched between 7.1 and 2.0 when necessary.
- Can change the volume of sides, center, front, mic, subwoofer, and rear independently.
- Removable side plates
 
The bad:
- 7.1 has no bass while listening to music, 2.0 is better but it is still muddy and overall not a very good experience.
- The top band has started to hurt my head after a couple hours of use.
- I can barely hear myself talk when I have these one, even when there is not sound coming through them. That speaks volumes about their noise-cancelling ability but it can be a con since I talk a lot during some games.
- Only work with PC
 
Overall these headphones are a great pair for any serious PC gamer. Most of the cons I found don't matter much to a PC gamer. While 360/PS3 support would be great, I understand the technical limitations involved in doing it. The biggest problem is the horrible sound of music when using them, but that's not what they are designed for anyway. They are designed for games, and in that area they excel.

 
This headphone have 10 DRIVERS so it's heavy and bulky headset

Gaming and movie (7.1 mode): enjoyable since you can spot location very easy.
 
Music (2.0 mode): if you listen music with 7.1 you can't not hear any bass. However, in 2.0 mode, the sound is extremly boomy and bloated.
 
Overall sound quality is muddy and bassy like a cheap close full can $ 50
