Did i get scammed into buying broken BeyerDynamic DT 990 Premium 600 Ohm headphones?

post #1 of 30
Thread Starter 

Hi,

 

Last week i purchased a set of these headphones from a reputable and authorized eBay seller:

 

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290979798442

 

 

Today i received them. I notice that the packaging box does NOT have a seal, you know the see-through tape that normal is used to seal these packages. Anyway i extracted the headphones and after plugging them into my Asus Xonar STX sound card, These headphones sound AWWWFFULLLL. I put on some bass heavy music and the bass just makes little popping and flapping sounds.

 

The headphones are 600Ohm version and my sound card supports it. I've never heard a blown head set before but im pretty sure this is what they would sound like. Maybe these headphones need to be burned in?

 

please respond guys im pissed off right now

Have you tried to adjust the gain setting for the Xonar card? The gain settings need to be raised for more demanding headphones.

 

The other thing though is that maybe the soundcard just does not have enough power for the 600 ohm load that these headphones have. That is how some massively underpowered headphones have been for me all distorted and whatnot.

 

However you should definitely treat them as coming broken as a possibility, the security seal should not be broken at all. The sellers feedback has some cased of defective units and problems like this despite their stores absurdly high feedback score.

It's certainly possible that they are busted, but it's also possible that you are just hearing distortion from your soundcard. 600 ohms is too much for some amps. Does the distortion go away at lower volumes? Is it only in the bass? If the answer to both of those questions is yes, I'd try the cans on a more powerful amp before assuming they are broken. However, you should definitely cover your ass and get in touch with the seller before your return period ends.

My Essence STX drives my DT990 Premium 600-Ohm headphones.

Hi!

 

There was NO seal what so ever. The packaging was basically NON sealed. Im almost certain that something of this value would have a security seal. When i opened the packaging the leather case that comes with it had like particles and dust on it. The particles look like wood splinters but tiny like 2-3mm long.

 

I youtubed some blown speakers and this is exactly what they sound like. They sound OK at low volume but when i crank it the bass gets distorted and pops and flaps.

 

and yes the gain is set at 300>600Ohm.

 

Also whats the difference between plugging these into the back of the xonar card and plugging it into the front panel. The headphones come with an adapter that makes the plug more bigger which only fits in the back of the sound card.

 

I WILL return these seeing as there is NO security seal....

Seal is broken, so chances are the headphone have been out of the box, so you might have been sent headphone that where returned before and sold to you as new.

In the Xonar Audio Center, just to the right of the Analog Out section, there is a little square, with what looks like a hammer on it,

it is the HP Advanced Setting, click on it, in the HP advanced setting, you want to set it to "Extra high Gain +18 300~600 Ohm".

 

Did you disable your on-board audio in the BIOS? when you installed the STX?

Might also try the third party "Unified Xonar Drivers", just in case you have a bad driver install.

 

When trying to play music audio, In the Xonar Audio Center is the Audio Channel set to 2-channel?

I downloaded the beta driver from the asus website because that was the only driver that would install. The other drivers would say 'sound card need additional power' when installing. 

 

I plug the sound card into my PCIE X16 slot because the other slot wont allow me to clamp down the sound card. I have a HAF 932 case. I also disabled my onboard sound in the bios.

 

And i did set the gain to 600 Ohm. The channel is set to 2 and the Sample Rate is at PCM 192 KHz, i tried switching around the settings and nothing makes it better.

 

When you purchased your headphones did it come with a security seal? there was literally no seal what so ever. The box was just bare. The leather case that it came with seemed to be dirty from particles too.

The front audio port can be used as an amplified headphone jack or a line-out jack.

You did hook up the STX's internal power connection?

The one that comes straight off the power supply.

a quick google found this

Sounds like your driver situation may be messed up, I'd try another source before giving up on the headphones

Hey guys i just watched an unboxing video of this headphones and my box doesnt even look the same!

OK after about 3 mins of the installer being stuck a message comes up saying

 

'Please plug-in UNi Xonar Audio device!'

 

WTF does this mean that i installed my sound card WRONG?

 

i downloaded the latest one NOT the stable one.
