DT770/990 Pro - 80 or 250 Ohms? - Page 2

post #16 of 26

It's worth trying them on your motherboard, but it may or may not sound better than the receiver. A real soundcard, or dedicated headphone amp, is really the way to go.

The Asus Xonar DG (PCI) sound card's headphone amplifier should be able to drive the 80-ohm DT770s.

The Xonar DG sells for $26.80 on Amazon, and there is a $10 mail in rebate this month.

Just noticed I failed hard not checking the way the link was presented by Yamaha's site.. anyways thanks for the answer. I ordered from eBay and haven't received a tracking number or anything, just an order receipt. Are tracking numbers not available from eBay purchases or something?

Tracking numbers are available for purchases from eBay, just depends on if the seller posts the tracking number.

Well I received them today, and they aren't as bassy as people described... just like MagicMan74 said. I haven't listened for very long yet or to vary many different songs but they are definitely comfortable from what I can gather so far. They are 2-3 times lighter weight than the G35, and very soft and don't clamp on the head too tightly. I don't see so far what the big hype is about though, they sound similar to the V6s but with more bass. Maybe it's like manbear said and my receiver Ohms are too high for the headphones or maybe the receiver is defective. I tried plugging the headphones into the computer but couldn't get any audio through to them.

 

I tried leaving the EQ flat and the windows volume maxed out, and whenever I go to anything over -8dB on the receiver the headset starts to distort voices when bass punches through. Should I goahead and just figure out what's going on with my computer's audio jacks and possibly purchase a DAC?

 

I've tried them with my cellphone, just to see what they are like. I have an LGL55C, not an amazing phone or anything but all that I have. It sounded to me like the phone couldn't output the same volumes as the receiver basically, I estimate about -32 dB in comparison to the receiver.

 

The noise isolation is excellent, when I had music on low volume and was trying to speak to people on TS3, I couldn't hear myself at all and it threw me off a bit. Without any music playing it still does an excellent job. I haven't tested these for several hours at once of use but I'm confident that they will be even more comfortable than the G35 at long hours, and that thing had no issues in the comfort area.

 

So re-cap of questions:

Is distortion for volumes above -8 dB from my receiver is it normal for voices to distort in a bassier song? My audio files are 320Kbps (mostly) mp3 files. I tested on youtube and had about the same experience. I had some FLACs laying around and tried those too, same thing. It's very slight though. Am I just reaching the volume limit or should I purchase a DAC and run it through my PC? (Or a soundcard)

 

 

Edit: Oh yeah, one more thing. I own a Pioneer SX-535 but it's on another state. I can have it shipped to me and I'd love to have it again. Any idea how that thing would hold up to the headphones?

In a proper system, you shouldn't get distortion at a volume that doesn't harm your eardrums, You can *make* anything distort. The dB scale on your receiver really means nothing. With most consumer grade amps & receivers "0 dB" on the volume knob is a completely arbitrary volume level.

Alright so should I be looking into a fiio or something?

Distortion is a sign that something's not right. I have a hard time believing that your receiver doesn't have enough power, though it's possible if you are close to maximum volume. 

 

It could be an impedance mismatch like I said earlier. If so, you can raise the impedance of your headphones by buying a cheap adapter like this one (get the 300 ohm version):http://www.ebay.com/itm/281188408675?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 

 

Be warned that this will make everything quieter. If you are already close to the volume limit on your amp, it might not be loud enough for you. But it's something you could try. 

Also check to make sure you don't have a digital volume control somewhere on your computer turned down, everything should be at 100%. 

I easily drove my 250 ohm DT990s using an 18v Cmoy from JDS Labs. You could use a cheap amp like this as long as your computer has a line out (not just a regular headphone jack).

I figured it out already, I had an eq effective causing the distortion :)

That could do it. Better now?
