New Sony Phones

Don't expect anything mixed and mastered to be consistent with all speaker configs much less different phones. I think you answered your own question when you said how much better it sounded on the Sony phones versus the Sennhiesers. Take also into account the difference in the sound being heard in earbuds. If you are just doing tracks for your entertainment and your friends, it may be enough. If you have aspirations of producing and selling your music, I can't think of one person who mixes and masters finished pro quality recordings just on phones. Even pro mixers and masterers use many different speaker combinations to test their mixes on. This is not meant to be judgemental towards you at all. It is just an opinion that I think you will find is a sound one. Good Luck and enjoy!

Phones are an important element in my mixing, although of course I do not rely on them as the only or final measure. My Bose phones are surprisingly close to my KRK monitors (at least perceptionally). To the OP's point, it would be nuts not to reference phones and earbuds since this is how 90% of your audience will hear your music (unless it is all dance-club oriented).

I would not use headphones to mix-

I would use even entry level studio monitors over phones, and compare your mix/master to a commercial track that is on the market that you truly appreciate the sound of.

Phones can be great to check some things on like panning, but music is so much easier to get sounding good in headphones - I speak from years of experience discovering this.

I have a Sony 7506 and it's a nice headphone.  But, I don't mix with headphones.  My primary mix is my studio monitors and then tweak as needed so it sounds on a Sony boombox and in a car stereo.

 And you ppls wonder why  i tell Ya MDR 7509's !!

I have been in mixing and mastering sessions with some real big dogs out here in L.A., and this is how they do it. Of course, a good mixing environment, aka a well treated room and decent monitors is key-

That's why you do not use cans to mix. Most are designed to make the music sound better..... more bass, more kick..... in other words they have built in coloration added. Some even advertise that as a selling point to the consumers.  BIG BASS SOUND.... just like your favorite artist....yadda yadda..... 

However, we should not be seeking the coloration ...especially at the tracking and mixing stages. Mixing should be done on a "truthful" system. Many times I have heard people make comments that studio monitors just don't "sound as good" as they would like them too. 

That's the point. If you can get the mix sounding good on studio flat response monitors, they should translate well to MOST other systems that the listening public will be using.... including headphones from various manufacturers with built in coloration...same goes for home and car stereo speaker systems. 

I use headphones in my studio all the time. BUT.... I use them to check a mix after I'm getting near the end of the process. I find if I wear them for more than a few seconds to a minute to check something,  they will throw my perception off, and I need to hit pause and go do something else for a few minutes before resuming the mixing process. 

In a pinch, I will mix with headphones if it is impossible to have the monitors on..... but in this case, I will always check the mix next day with monitors. It helps to "learn the cans" if you plan to ever mix with them. Any mix done with cans almost always needs tweeks  on the monitors.
