I thought this would be a good topic to throw open for discussion. I recently mixed a song through the monitors, A/B'ing them with a second set of monitors and even checked them on a high quality set of monitor headphones. The mix sounded really good to the point I was happy with it, but then I thought I would listen to it through a set of iphone style earbuds...not something I really do with my mixes but every now and then I may check just to listen to how they translate. Disaster...the mix sounded like I was listening to it through a set of soup cans. All those lovely clear mids and warm low end had all but disappeared and the whole thing sounded like mud through said soup cans. It sounded like I had overdone the reverb to the point of ridiculous and the mix sounded like it had a stereo spread about 60 foot wide...but when you listen to it through monitors or headphones it sounded fine. Thinking it may be the earbuds I reached for another pair...same result only slightly better....then another pair...same result. Whats the point in compromising a mix that sounds great through monitors just for the sake of making it sound half decent through earbuds? Are we just mixing to the lowest common denominator when we take into account how its going to sound through $5 earbuds compared to those big-dollar monitors we spent a months' pay on? I know that there is the whole "but everybody is listening to music on earbuds these days..." arguement, and the target audience and their listening habits are a consideration, but should the sound of the fininshed mix have to be compromised to cater for how it sounds through cheap earbuds? My view is that surely anything I do to try to improve how it sounds through earbuds it going to have an effect on how it sounds through the monitors, and dare I say a detrimental effect at that. So, say I'm mixing for a client and they plan to upload their music to a platform where their music is going to be streamed or downloaded and listened to by the majority through those $5 earbuds, do I just do away with those expensive monitors and spend my days A / B'ing through 5 sets of cheap earbuds just to cater to that?.. Or do I just continue mixing through the monitors and monitor headphones and not care how things sound through cheap earbuds or worry about the lowest common denominator? Or do I do two mixes, one that sounds great through the monitors and one that sounds great through earbuds and hope they upload the right one? With more and more music being downloaded and streamed by the day, is this something that we have to start incorporating more into our workflow?..checking the mix through yet another medium? There seems to be polar opposite schools of thought depending on where and what you read. Some say it should be something that is taken into account nowdays whereas there are some who believe its a bad idea. Its something that has got me second-guessing my mix now. What say you...what would / do you do?
