I don't really understand the Ohms... do these need some sort of additional device or can I just use them on my laptop? Sorry not an audio pro :(

You *can* run them off of your laptop, but they won't sound very good. You will need some kind of amplifier. Fiio makes some good amps for the money. I would suggest something in the $40 to $100 range. You won't be dissapointed though, these headphones are awesome.

I would think that they could be plugged into your earphone jack on your laptop. I can use them plugged into my Nexus android and the sound is very good and sharp.

Sorry! This question exceeds my pay grade. I've always used only 4 ohm, only 8 ohm or switchable 4 to 8 ohm speakers together.

Depends on what the total ohms are. And if the computer speakers arent close to the same watts they won't work. I Believe it's 4 or 8 ohm stable.

They will only get as loud as the device you are listening to. I can plug them in my laptop, turn volume way up and hear clear without them in my head. The sound quality is fairly decent also.

Don't insert headphones. The impedance won't be correct. There weren't speaker cables included in mine. Sorry!

No they can not connect directly to your laptop. They do require a stereo amplifier.

I don't own these (just looking at getting them), but I assume that it's because of the 4-conductor on these (extra conductor for the mic). The socket at the gym is made for 3-conductor (ground, left channel, and right channel), i.e. just audio. If you plugged these in and they didn't work, you need to test them to make sure they didn't short and blow something out.

Not the 250 ohm. If you want to use them with a phone, I'd suggest the 32 Ohm version; get the Limited Edition if you can find them, they are nice. But if you are using a phone as your primary source, and want something on par SQ wise and more portable, check out the Sennheiser HD25 or Amperior. Both are more easily driven, and more portable too, with a similar V-shaped response to the DT770. Their sound is less spacious, but I prefer them to the DT770 when both are driven by my Nexus 4 (same chipset as your optimus G).

Hi, I could be wrong here but most laptops have a separate input for a microphone.... if so then all ear buds are made for cell phone microphone not a solely independent microphone. But if u have tried other ear buds and they work then u would be correct that could be either incompatible or defective.

I do not know the sensitivity but your laptop can definitely drive them adequetly. They do have 50ohm resistance.

They can get LOUD! You cannot plug them directly into a computer; you will need a receiver/amplifier as a bridge as others suggested. After I sent the crossovers over to Ed Frais @ EFE they are now music to the ears! Difference is night and day after the mod!!

I dont think theres a way to plug them to a laptop because they need wire from both ends or banana plugs. Mine are hooked to my receiver and I use the mirror feature on my macbook pro and it works fine. I would recommend you get an amp. These speakers are amazing for the price!!!!

They're supposed to be 4 Ohms even though the back says "4/8 Ohms" but in reality they're less than 4 Ohms - a tad under 3.5 Ohms. unless your amp/reciver can tolerate resistance of 2 Ohms which very few can, don't wire them in parallel with an 8 Ohm speaker. I did and it almost fried my receiver.

one more thing i forgot to mention son. remember this system is a 4 ohm system. you cannot hook it up to a "normal" stereo receiver because they are almost all wired for 8 ohm. my son`s friend bought these after hearing them at my house and hooked them to an integrated amplifier his buddy gave him and blew them up. my apologies if you already were aware of this.

They work fine. The impedance is 32 ohms or something. That's supposed to work okay with standard modern headphone jacks (like on a portable digital music player or laptop)

I bought these for work but experimented at home first. I also tested on two Denon Recievers, Denon 3312 and the older 2807 (now at work). First of all your amp should be high current or rated for 6 ohms, (these are 6 ohm speakers), I was surprised how far I needed to turn the volume up on both Denons. At home, room size is about what you have, I was ok with the sound they produced until I tried them with one of my subwoofers, I was blown away! I actually checked to see if my Infinity Beta 50's where playing the music. At work with the old 2807 Denon no sub in a large warehouse co-workers have stopped and commented on how nice the music sounds. Sorry for the long answer, I would say if your reciever can handle 6 ohm and you use a subwoofer you will be happy you bought these.
