Not for making mix decisions.

Well I thought headphones are not good for mixing but they are good for tracking. Or are headphones good for both? Anyways are these headphones good for tracking then?

For tracking it doesn't matter what they sound like, they just need to be comfortable for more than 10 minutes.

If they were free then whats the question? Use em and if you dont like them then buy something else. These are the lowest of the low level phones so tight symphonic sound is probably not going to happen.

Well is it true that you should not use any headphones for mixing? Or can you use them for mixing? I just head some people say never mix with headphones. They say mix on speakers is the best.

Also I do have the option to return these Sonys and get the MDR-V300 instead and I will only have to pay around $12 since normaly they cost $32 at Amazon and I have a $20 promo discount so it will be $12. Sony sells these for $50 so they are a step up of cource. I heard some people use these also for there home studio that are in a budget. I assume it will also get the job done like the V150 but probley little better since the V300 is better.

I already said that. You cannot mix properly on headphones. It isn't the answer beginners want to hear but it doesn't change the fact. You will read all sorts of anecdotes by people who claim to mix on headphones. Who is playing their CDs? No one is.

You'll have a hard time mixing on speakers in a questionable room. Headphones are for checking, hearing extreme panning, and whether or not efx are exaggerated. If your recording a band make sure you have enough of the same kind for everyone, and one for the engineer too. Expect your studio's phones to be dropped, spilled on, stepped on, ripped out of sockets, blown, never, ever be 'loud enough', sweated into. 12 dollar headphones are just that. if they're decent you can track with them, unless you train your ear to them, you'll be daissapointed w/ your mix decisions. AKG k44's are cheap, decent tracking phones, for a modest studio.

Headphones w/ decent isolation really help w/ the "not loud enough" factor.
They help even more when a drummer is in the same room.

Unfortunately, you pay more for isolation.
Typically you need closed-back and circumaural (around the ear) type headphones for good isolation.
Expect to pay $50-$250 a pair for these.

I too have been looking at "decent" headphones in the $20-$30 range.
I have more expensive headphones that get beat up, and want a few beaters. Haven't pulled the trigger on one yet.

Well I did yesterday ordered the Sony MDR-V300 since I heard they are better than the Sony MDR-7502 and both have the same price range. Hopefuly these will be better than the $20 one. But I might like the V150 more I don't know but just have to listen to the V300 when they come tomorrow and compair them and see which I want to use more. I would assume the V300 will give better sound since they are a step up from the V150. But if they are not worth the upgrade I can always return them to Amazon and keep the V150. I will have to return one of them since I don't need both.

I have been testing both sets and I noticed that the V300 has little more clear highs meaning it's little more brighter. So overall I think the V300 sounds better. Not night and day difference sound wise. The cord is 10 food long and the plugs are gold plated and it has a 1/4" plug and it's a screw type so that's good. The V150 had a 6 foot 6 inch cord and had a nickle plating and had a normaly 1/4" plug not screw type. Also the V300 even has a folding design so it makes it more portable. But the V150 is very good for $20. I mean they do sound amazing for just $20 but of cource the features are better and the overall highs is better on a $50 headphones. Also I don't have to turn up the volume as much to get the same loudness as the V150. I do see the specs say that the V150 sensitivity is 98dB/mW and the V300 is 102dB/mW both are at 24 ohms.

Neither pair is good for making mixing decisions. Hyped is the word for the high end. You need completely flat brutally honest response to make mix decisions. 99% of headphones don't fall in that category. Whether they "sound good" is of little concern to an audio engineer. Comfortable-yes. Of course for tracking it doesn't matter. You are making any real decisions at that stage.

Well if even the V300 isn't good for mixing or so then probley I should just return them and just keep the V150 since for $20 they do sound really good to me. But I guess pretty much all headphones aren't good for mixing but are good for tracking of cource.

I did still had both the MDR-V150 and the V300 but I decided to keep the MDR-V300 since overall I did hear my music more clear than the $20 ones. I did get my money back for the V150. I know not to use these for mixing and only for tracking or checking. I wish you could use headphones for mixing though. But I guess I will mix on my Cakewalk MA-7A monitors since it's best to mix on speakers.
