Q: I’m thinking of asking for the iPod classic this holiday season. My iPod video broke and is out of warranty. I was wondering if you think it would be a good idea to wait until next year before buying in case they come with a better version? Or do you think it’d be better to just buy now?
- Anna
A: This is a question that comes up very frequently in our iLounge Discussion Forums, and the usual answer is that if you’re waiting for the next release of a product, then you’ll always be waiting, because there’s always going to be something better coming along eventually.
That having been said, however, the reality is that the iPod classic was only released this past September. Although Apple does not normally provide any kind of road map for product releases, past iPod models and their release dates provide enough insight that it’s reasonably safe to assume that we’re not going to see any significant updates to the iPod classic line before next fall at the very soonest.
For example, the fifth-generation iPod was released in October, 2005, in a 30GB and 60GB capacity. September 2006 brought a minor upgrade to this line in the form of an 80GB model, and some minor improvements to battery life and screen brightness. It was not until just this past September that a major update occurred in the form of the iPod classic (or the sixth-generation iPod, if you prefer).
So while the decision is ultimately up to each end user, this is probably a very safe time to purchase an iPod classic, since it has been out for long enough that most of the problems have been worked out in recent firmware updates, yet not so long that a new device is right around the corner.
One word of caution, however: If you used the TV output features of your fifth-generation iPod and had invested in accessories already for this purpose, you will very likely find that most of these will not be compatible with the iPod classic. With the release of the 2007 iPod models, Apple has limited the video output to the Dock Connector only (rather than the headphone port) and only for accessories that include a specific Apple authentication chip. Therefore, if you plan to purchase an iPod classic and use the TV output capabilities, you will also need to factor in the cost of a compatible TV output cable such as the Apple Composite AV Cable (iLounge rating: C). Unfortunately, these accessories are currently somewhat limited, although we suspect that more will appear in early 2008 as third-party accessory manufacturers begin to incorporate the necessary hardware to enable video output on the 2007 iPod models.
Note that this only affects video accessories. The iPod classic remains compatible with pretty much all of the same audio accessories (ie, speakers, car kits, etc) that were supported by the fifth-generation iPod.
Q: If I get a new iPod, can I transfer music from my old one to the new one?
- Amanda
A: You can definitely transfer your music from one iPod to another, although this may be a bit more complicated if you have not been maintaining your library in iTunes on your computer already.
If you have your library in iTunes and are using automatic synchronization with your existing iPod, then transferring your music to the new iPod is literally as simple as plugging it in and going through a very brief setup wizard to select automatic synchronization. The content of your iTunes library will be automatically transferred to the new iPod, and you can even use both iPods at the same time, with the same iTunes library.
On the other hand, if you have been managing your iPod content manually, and your music is therefore only on your iPod, the process may be slightly more complicated—basically you will first need to recover the content from your iPod back into your iTunes library, and then use that information to reload the content onto your new iPod.
With the exception of content purchased from the iTunes Store, iTunes itself does not provide any means for transferring content from an iPod back to your iTunes library. Fortunately, there are a number of third-party utilities that fill this void, and this process is discussed in much more detail in our tutorial Copying Content from your iPod to your Computer.
Essentially, once you have recovered the content from your old iPod, and loaded it back into your iTunes library (a process made extremely simple by some of the tools described in the above article), you would then simply connect your new iPod to your iTunes library, and load the content from there normally.
Q: I have a second-generation iPod nano and I have recently purchased an 80 GB iPod classic for home stereo use. I want to transfer the existing nano iTunes playlist to my new classic but, once transferred, I also want to convert the songs in that playlist from a 128 kbps bitrate to Apple Lossless for better sound quality. Does it matter, in terms of sound quality, whether I carry out that conversion using the iTunes preferences or would it be better for me to re-digitize my entire CD collection to iTunes from scratch?
- Parker
A: This actually matters a great deal. Converting a 128kbps audio file to any higher bitrate will not result in any improvement in sound quality—merely a larger file size at the same quality. In other words, there’s no point in even bothering to do this—you won’t get any improvement in audio quality.
Low bit-rate audio formats such as MP3 and AAC accomplish their small file sizes through the use of what is known as “lossy” compression. Essentially this means that the music track is analyzed, and certain audio content is discarded completely from the resulting file. Most of the time, this discarded content is in frequencies that cannot be heard by the average person using average equipment, and therefore is unnoticeable by most people. Of course, the higher the bit-rate, the more information is retained, which is why there is much debate about the quality of different bit-rates—something that is almost always a completely subjective decision based on your own ears and the equipment that you are using to listen to your music.
For comparative purposes, an original CD audio track is encoded at 1,440 kbps, or 1,440,000 bits of data for each second of audio. On the other hand, a 128kbps MP3 file only contains 128,000 bits of data for each second of audio. This means that in a 128kbps MP3 file, you have effectively lost 1,312,000 bits of information per second. This has been stripped out of the resulting MP3 file during the initial conversion process, and is never coming back. Therefore, converting this 128kbps MP3 file back to an original CD audio track is basically going to insert 1,312,000 bits of dead air into each second of audio—you’ll end up with a larger file with no actual increase in sound quality. In short, you can’t get data back that wasn’t there in the first place.
On the other hand, as their name implies, lossless formats such as Apple Lossless compress the audio stream without losing any data. The result is a smaller file at the equivalent quality of the original CD. The resulting file sizes of Apple Lossless files vary depending upon the original source, since some audio files will compress better than others, but on average they’re usually around 50-70% of the original CD track. Further, since these are lossless formats, they can be used to burn audio CDs, or re-convert to other audio formats in the same way the original audio CD could be—all of the original audio information is present, it’s merely compressed into a smaller file size (in much the same way that a ZIP file works).
So if you’re converting to any higher quality format, whether it’s Apple Lossless or simply a higher bit-rate MP3, you should always re-rip from a lossless source (ie, the original CD), since there’s absolutely no point in doing the conversion otherwise.

Q: I like to play video concerts on my iPod just for the music, but the video drains the battery too fast. If I set the the iPod to TV out so that the video doesn’t show up on the screen, will this extend the battery life?
- Dave
A: This will extend the battery life, although on a hard-drive based iPod it will not be as much of an increase as you might expect.
The two major sources of battery drain on the iPod classic and prior models of hard-drive based iPod are the LCD backlight and the hard drive. Setting your videos to play audio only via the “TV Output” option will increase battery life by preventing the backlight from turning on, but will still have an impact on the hard drive.
The problem is that the hard-drive based iPod models conserve battery power through the use of a memory buffer—when listening to a playlist, the hard drive spins up, loads a certain amount of data into the buffer, and then spins down and goes to sleep. This means that most of the time the iPod is playing music from the memory buffer rather than accessing the hard drive. Since the buffer is a finite size, however, the larger the original source track, the less information the buffer can contain—therefore the hard drive has to be read more often to refill the buffer.
For normal 128kbps music tracks, the buffer can hold approximately 30-60 minutes of music on a fifth-generation iPod or iPod classic. However, a video file is significantly larger, and even if you are not playing the video portion of the file, it still needs to be read into the iPod’s buffer. The result is that the hard drive needs to spin up considerably more often—generally every 5-10 minutes depending upon the bit-rate of the source video itself.
This same scenario applies to higher bit-rate audio tracks. For example, Apple Lossless and AIFF tracks have a dramatic effect on battery life as compared to 128kbps MP3/AAC tracks.
So while you will see some battery savings from not having the backlight on, the increased hard drive access is still going to drain your battery at a much faster rate than if you were listening to audio tracks.
If battery life is a primary concern, you may want to consider extracting the audio portion of these video tracks and transferring it to your iPod as a separate audio-only track. There are a number of video/audio editing tools out there that can be used to accomplish this for non-DRM-protected videos.
Note that this will not be a factor on flash-based iPod models such as the 2007 iPod nano (with video), or the iPod touch or iPhone. These models have no hard drive and are therefore more power-efficient in this regard. Unfortunately, these models also do not offer the ability to enable the TV Output feature without connecting a compatible accessory. If you tag your tracks as “Music Videos” and fill in the artist/album track info, you will be able to access them through the iPod’s “Music” menu to listen to the audio portion only. This avoids the need to enable the “TV Output” feature when you only want to listen to the audio, although it unfortunately does not change the way in which the iPod reads in the track information, since the video information must still be read in to play back the audio.
Q: I have a iPod nano and I was wondering where if they have Bluetooth headphones for nano? I am looking for wireless. Are the headphones ear buds?
- Cely
A: None of the current iPod models provide any direct Bluetooth support, although there are a number of third-party iPod-compatible accessories that provide both the Bluetooth adapter to connect to the iPod and the headphones themselves.
One such model that we’ve recently reviewed is the iSkin Cerulean F1+TX Wireless Headset and Transmitter (iLounge rating: B-) which provides an adapter to connect to the iPod Dock Connector and a set of earbud-style headphones.
A complete list of reviews on Bluetooth and other wireless iPod accessories can be found in our Bluetooth/Wireless Home Audio Accessory Reviews.
Q: I just purchased the Universal Dock along with the Apple Component AV cables. When using the 30-pin connector from the Universal Dock and plugging in the RCAs into the back of my stereo, I’m still having to use the volume control on my iPod. I didn’t want this as I wanted to ensure I’m getting the best quality possible without amplifying my music twice? Is there a setting on the iPod for disabling this?
- Paul
A: Actually, the Apple Universal Dock does not amplify the iPod output - it merely attenuates it. In other words, the output volume of the iPod is not increased - a volume control is merely provided to allow the user to decrease the volume.
This has created some confusion with regards to the newer Apple accessories and recent-model iPods, as it is easy to assume (incorrectly) from this behavior that the iPod is not sending a fixed line-out signal through the Dock Connector. In reality, however, the line-level that comes out of the Dock Connector is fixed, and with most iPod accessories the volume control setting on the iPod will have no effect. The issue here is that specific Apple accessories such as the Apple Universal Dock and iPod Hi-Fi are able to read the iPod volume setting. In this case, the iPod still outputs a fixed line-level signal via the Dock Connector, but the connected accessory reads the volume setting from the iPod and adjusts its output level accordingly.
As one would expect, in the case of speakers such as the iPod Hi-Fi, this will involve amplification by the speakers themselves (in the same way that a volume control works on any speaker system). The Universal Dock, however, does not include any amplification hardware, and simply acts as an attenuator to allow the user to reduce the volume output level. This is the Dock itself performing this function—the output from the iPod itself remains constant.
Bear in mind that this volume control function only works with very specific iPod accessories—thus far only a few accessories made by Apple themselves take advantage of this iPod-based volume control function. Most third-party speakers and Dock Connector audio accessories will completely ignore the volume setting on the iPod.
For example, if you connect your iPod to an older Dock Connector based audio accessory (such as the fourth-generation iPod Dock), you will discover that the volume control on the iPod itself has no effect—the older Docks do not read the volume from the iPod, and therefore simply ignore it. Further, if you compare the audio output levels between the older Dock and the Apple Universal Dock, you will discover that the maximum volume setting on the Apple Universal Dock is equivalent to the fixed volume output from the older Dock.
