Battery Life

Kicking off our objective benchmarking we have the battery life benchmarks for our MP3 players. Skimping on battery life is one way manufacturers can make a product thinner through a smaller battery, but if the battery life is too low then it works against a device by requiring it to be tethered to a charger too much.

For our tests, we ran each device from a full charge until it stopped playing, recording how long it took. The volume was at a moderate volume, and the device went untouched the entire time. This has a slight bias effect because it results in the screen being turned on less often than under normal usage for music, but the effect should be fairly consistent among the players.

For both the Zune and iPod Touch, WiFi was enabled. For movie playback we used a movie encoded in H.264 at 1.5Mbps 640x480, which is the average resolution and bitrate for a video purchased from Apple's store.

Because the iPod Classic is built primarily as an audio player, this is one of the areas where it shines the most. With 34 hours of playing time (4 hours over spec), it lasts for a ridiculous amount of time that neither the iPod Touch nor Zune can touch. We're confident that 34 hours should be enough for anyone, and if that's not enough the 160GB version has a spec of 40 hours play time.

The original Zune was a power hog, and while Microsoft has improved on it some with the Zune 80, it still fails to break 20 hours, when the specifications for the Zune 80 call for 29 hours. Given that the screen is off for music playback and the WiFi implementation should not be drawing a lot of power, we're left to wonder if it's just an inefficient design, an undersized battery, or if something else is going on. Microsoft has access to the same hard drives as Apple so there aren't many potential candidates to explain the limited run time compared to the Classic.

Finally the Touch performs well enough but still can't touch the iPod Classic. At nearly 22 hours it provides enough run time if all you're doing is listening to music, but 22 hours is probably going to be an overestimate of actual run time due to all of the other (power sucking) functionality of the Touch. We had expected a bit more out of the Touch given that it is a flash based player.

For video, screen size becomes a matter of importance. It should be unsurprising that the iPod Classic, the device with the smallest screen is the winner here with 6 hours. But as we feel the screen size is too small to be practical, we'd consider this a hollow victory for Apple.

We follow this with the Touch, which is definitely not a hollow victory for Apple at 5 hours and 30 minutes. The Touch has the biggest screen of all of these devices, so to come in so close to the Classic is a very good situation for the Touch. We suspect what it loses due to the screen is picked up from being a flash based device.

And finally we have the Zune, which has the worst of both worlds with a large screen and a hard drive. While the Zune could claim to trail the Touch in audio, it's nowhere close in video. 3 hours and 15 minutes will get you a movie and some music time, but we'd call anything under 4 hours uncomfortably short.

    A mac IS a PC these days, only with fewer hardware choices and OSX instead of Windows/Linux, etc...

    Interesting. I really like the Zune but use Macs for my everyday computing. Go figure! I do have Windows machines also but it would be nice if MS made the Zune work with OSX. I know many with Macs who like the Zune.

    I know I'm not alone in this and as wrong as it maybe, everytime I see someone with a Zune, I think that that person could either not afford or was too cheap to pay for an ipod.

    Riight...

    zune 80gb $249.99
    ipod 80gb $249.00

    Looks like all those "poor people" had to go cheap and shell out an extra $0.99 for their zune...

    Brilliant. A+ for you.

    I want to commend you on nailing a huge issue in your introduction - gift cards. I was thnking about getting one of the lasser known MP3 brands - but I had to by my plasyer with BestBuy gift cards, so that ruled out a lot of my choices. I ended up going with the 8G Ipod Nano, since I liked that out of my choices at BestBuy. When your stuck with BestBuy, to really only have a few choices for a high end MP3 player.

    The only reason I bought an iPod was because at the time they were the only players that could be controlled by car head units. Just did a quick search and I couldn't really see anything for Zune's. Since I bought my head unit (Alpine) the number of iPod compatible decks (after market and stock) has increased significantly too.

    Almost every review I have read that compares the zune 80 to the Ipod classic points out one very import feature: the superior sound quality if the zune. It isn't the earbuds its the sound quality of the base components. I took my the earbuds that came with my zune 80 and listened to many of the competition, and there is no comparison; the zune 80 is superior. As with the Iphone and its horrible call quality, the marketing of the cult and its design ignores the purpose of the device. This should be about sound quality being the primary concern. The fact that you were craving for an equalizers shows how little you understand about the sound quality issue. Did you understand that you are to fully place the zune earbuds into your ear to get the proper bass sound? I also question if you gave yourself enough time to get used to the zunes control features. It was into the third week before I started to get used to the short cuts. I will stick with cnet and pcmag if you produce reviews such as this.

    I should clarify. By competition, I mean apple products. The creative products produce great sound. I haven't been able to compare to iriver devices, but the cnet folks have. This is really simple when shopping for these devices do look at the reviews, but then take your favorite set of headphones or buds (apple buds the exception) and listen to each device in the store. You will find the listening difference between the apple products and many of the others is analogous to dragging your hand across raw cardboard compared to fine finished wood. We have become so used to bad quality that we don't realize how good it can be.

    People,d the reason you shouldn't include stuff like the Zen and the Karma is that they are discontinued (in the case of the Karmas for a few years now). The Zen Vision: M is the closes to a direct competitor that Creative made to these two, and it is discontinued. We can throw the Cowon X5 in there as well. The new Zen I don't find comparable because it is flash based. It would be nice to see a flash comparison (where the Zune and iPods would get handed to it in price/performance and features, although the Touch would do well but it costs put it out of most people's consideration). There is a reason why there isn't any company making a music focused HDD based player, trying to compete with Microsoft and Apple is asking to lose money, and neither of those two are really competitive in the flash based players (at least on features and price), which allows them to actually compete. Of course that doesn't stop the iPods and Zunes from outselling them still.

    As for the slowdown on the Classic, have you tried using one with the updated firmware? The launch units did have some very bad slowdown, but it has since been resolved and is now much speedier.

    On the sound quality side, I was a bit unimpressed, as hooking them up to machines to check their sound quality doesn't tell the whole story. I have not seen a single person who has heard both the Classic or recent iPods (which many say sound better than the Classic although some say the Classic is better as well) and the Zunes who did not say the Zunes sound much better to their ears. The Zune 80 especially is known to have an execptionally clean headphone out (most people don't recognize noise in the signal when they hear it, mostly because they aren't used to using higher quality audio components, and no I'm not talking $50,000 speakers here either).

    Thats not to say the author's findings aren't valid, they just don't tell the whole story. I suggest checking out one of the many DAP/PMP review sites (such as DAPReview, AnythingbutiPod) and also forums such as the portable audio one on Head-Fi if you want more user consensus and in depth testing.

    Bottom line, if you need the storage and don't want to spend to get into the PMP category, then the iPod Classic or Zune are both quite good, each with its own strenghts. For flash players, the new Zen is very nice but has issues with the SD expansion slot (it doesn't integrate its music and other files with that of those on the players internal memory). The Cowon D2 is very good, although I'd wait because I think they're probably going to up capacity on them fairly soon. In that same vein the iRiver Clix 2 is pretty nice as is the Meizu M6 I think its called. The Sandisk Sansas are ok, but they are targeted more at packing features in than actually being that good at anything (sound quality, interface, etc). Lastly, there is the new Sony players, which although they lack the expansion slots that have become defacto, they have gotten rid of needing software for use and all the DRM crap that hurt Sony so badly. Also they compete well with the iPod and Zunes in price and features, all the while having some of if not the best sound from a portable music player. Personally, I wouldn't even consider the flash based iPods or Zunes at all as they're high on price and low on features compared to the competition. Couple that with Amazon being a better place to get music online than either iTunes or the Zune marketplace (no DRM at all, not just on some music, competitive price with better quality) and there's no reason to tie yourself to a setup like that (Amazon has a utility that will sync your downloads from them with iTunes so thats a non-issue).

    Any "high-end" MP3 player comparisons should also include the Rio Karma for a few reasons:
    The Karma is the de-facto standard in sound quality for MP3 files, and includes a dock that allows one to output line-level audio, bypassing the internal amplifier

    The Karma includes a 5-band parametric equalizer. Not only can you individually adjust any of the five bands, but you can also change the scope of the adjustment, as the "width" of the band is customizable

    The Karma is the only player that supports proper gapless playback with regular MP3 files. I don't know about you, but pauses and clicks where the music should be seamless is a huge reduction in sound quality.

    The Karma is the only player that supports free codecs of both lossy and lossless variety. If MP3 suddenly goes the way of the GIF (i.e. the format creator starts pursuing royalties more aggressively) and your mp3's are outlawed, the Karma will still play OGG and FLAC files, formats that cannot be patented or restricted.


    Basically, if you are comparing "MP3 Players", first and foremost judge them on how well they PLAY MP3's. I consider that any player wishing for itself to be considered "high end" should produce good sound quality without skipping or popping between tracks - which neither the iPod or Zune can. Everything else is pretty much gravy - whether it's a user interface that's not steeped in heavy geek, whether it's tight integration with a media management suite or music store, whether it's the ability to play videos or squirt. A high-end MP3 player should play MP3's better than anything else, and that's not what the iPod or the Zune offer.
