You mean God? No, its not from God. It's more of a science thingy. What exactly is so funny about improving the sound or video of your MP4 player? Dont knock it til you've tried it. The world is full of milllions of things you don't and/or cant understand. This is just one of them.

Actually, science is bs & fake. There is a God. :wink: :)

hows about a sticky?
did this to a friends old (CHEAP!) 128MB player and it worked a charm.
he is happy :D

Good idea, but that's the admin's decision. Say... didn't the admin (or perhaps the moderator?) say he'd try it? What's the verdict?!

Great. Now try it on your own mp4 player! The method has the potential to improve both sound and video quality (although video is really something that's harder to tell, especially if you dont know what to look for). I know some people are wary about sticking their players in the freezer, but so long as the instructions are followed (ie. dont try to turn it on immediately after taking it out of the freezer or fridge), well I've done this to a lot of mp3/mp4 players and other electronics without any problem (I can recommend putting the player in a zip loc bag for those worried about condensation, but I have -never- used a bag with anything, and I think the results can be ever-so slightly better without one).

Thanks for this idea to improve MP4 sound quality. Now I understand why Al Gore at an Academy Award, and how the whole "Global Warming" thang could have gotten started!!!

Hmm ... i dont think that this is gonna make much defference .. but ill try it anyway .. Hell... my mpx player fell in the toilet once and nittin happened to it .. so what can a little ice do ? :P

At worst, you are without your player for a day or two. I've frozen digital cameras, mp3/mp4 players, dvd players, watches, telephones, speakers... you name it, never had a problem. Place it in a zip loc plastic bag if you're -really- worried, but follow the instructions carefully, especially the part about listening to a certain song before you freeze it! (Otherwise, you will not have a very good reference to know whether it has improved things or not). Let me know how it went.

Just a word of caution to newbies: It's ok to freeze mp4 players as they work on a small voltage (3.7v).
But if someone decides to put their DVD player or amplifier in the freezer - make sure the place where you thaw it is low in humidity - cold metal will easily attract moisture to condense on it - and if plugged in without it being completely dry, you will most likely blow something.

Being a speaker designer, I would also caution against putting quality speaker drivers in the freezer, especially speakers with polypropeline cones and/or rubber surrounds.

Re: How to improve your Chipod audio/video quality for free
 

I agree that if you freeze amps, dvd players, to ensure it is dry before plugging in (remove the covers, as I do, but freeze them as well). That said, I have frozen amps, dvd players and the like, leaving them to thaw slowly over a period of a half day or a day, wrapped up in thick blankets to slow thawing. I check if they're dry and don't plug them in if they are still cold, of course. Never had a problem. I have also frozen quality speaker drivers with poly cones and rubber surrounds, and their xovers and all wiring, after removing them from their cabinets. Again, never caused a problem, the speakers sounded much better after I finished the project.

As a speaker designer, you must have a lot of speakers on hand. Try it on throwaway speakers if you are curious to see what effect it might have, and whether it will damage the drivers.

Re: How to improve your Chipod audio/video quality for free
 

As a speaker transducer / driver designer, I work with materials & their properties.
Exposing a plastic such as PP to temperatures way below freezing will & do cause hardening or brittleness of the material at room temperatures. (a study of the material's behaviour over temperatures will tell you so). This in turn will harshen the sound above the cone's break-up point. (the break-up is more harsh due to lower damping). This is one of the reasons why some of the best speakers do not use plastic based cones, as they tend to sound different over time.

Secondly, a large driver, with a 3" voice coil will on an average have a coil with the wire length exceeding 50 meters. As a part of the curing process of some of the high-end coils, we heat them to a temperature above 500F while ensuring that the coil is in a fixture and not allowed to change shape.
Besides, the metal (copper / aluminum) in the coil will again heat up quickly the next time you feed real power into the speaker, thus neutralizing any positive effect the freezing might have had on it.

As I said before - this stands more true for the larger high power drivers & those using plastic / PP parts.
