When I got it out of the box, it was a truly magnificent sight! The metal alloy body was just excellent and the 'saucepan' design with its smooth clean curves really did look unique and trust me when I say, you'll look at this thing for a good hour or so without even listening to it all!!! That said, what really matters was the build quality and this was as high as it gets. The body seems to be made of mainly metal but has the same weight as plastic. Overall, if you count in the base of the CD player, it isn't as thin as say the D-EJ2000 (flagship standard CD walkman), but because of its sauce pan design, it actually has a very small volume and therefore is extremely light. The remote controller plugs underneath the top lid (in the bottom saucer section) so it doesn't extrude out, which is very convenient as I found this to be quite annoying in previous CD walkmans. Apart from this the rest of the equipment supplied is top notch too, including a very cool glass charging cradle and a extra AA battery pack which can also be used to charge the walkman. The remote controller is the latest version and is very efficient in its design as it allows access to all settings without being too cumbersome. The walkman also uses just one Ni-MH battery stick which is unexpected, but it seems to be enough as the walkman, fully charged (with frequent use) ran for a whole week!
With build quality and design being near perfect, I tested the actual sound quality. Sadly, this is where things went a bit wrong. Firstly the supplied earphones look great but sound downright dreadful and suite those free radios you get rather than a £140 CD walkman and I strongly recommend you bin them as soon as you can and buy some quality ones. But what really annoyed me was that I knew Sony only did this for profit as they would have to force people to go and buy a decent pair. This has been a very bad trend for Sony and really does destroy their reputation as a high quality brand. I could remember the ‘Groove Fontopia’ earbuds they use to supply with their cassette/CD walkmans before and these were very good with deep bass and clean treble, but then they suddenly ditched them and started to supply the cheap open air earphones, even with the latest £200+ minidisk walkmans. But now they have gone a step further and supplied even more rubbish earphones! Luckily for me I already had a pair of Sony MDR-EX71SL ear buds which made things sound as they should. This is really disappointing for most people as it would mean having to pay an extra £20 or so for some quality ear/head phones. Bad news for Sony and their reputation!
The next problem with the sound is the new ‘Parametric Equaliser’. Don’t get me wrong, when I say this is a problem, because I was really pleased that Sony had finally moved up a step and included a customisable equaliser. The problem is that they didn’t implement it very well. I can’t understand why they made things so awkward? For example, you can only control certain parts of the equaliser spectrum, which makes the overall shape of the equaliser very uneven and therefore the different frequencies don’t sound right. You only get to control 1 of 3 different sections in the low, medium and high band ranges which makes the whole customisation process very difficult. This all equates to a really inefficient equaliser design which is totally unnecessary when a simple 6-10 band graphical equaliser (ranging from 60Hz-16Khz) would have been much better as it would have given you much better control over the frequency ranges without any confusion. The sound itself is top quality, but in terms of raw power output it isn’t as powerful as it should be. Even with the MDR-EX71SLs the bass sounds slightly weak. That said it still sounds very good with clear treble and mid ranging sounds. Also, if you get too confused with the custom equaliser settings the ‘Heavy’ preset setting still sounds good.
Music CD playback is obviously high quality, but more importantly the playback of MP3 is very good and has so far played all the mp3s I’ve thrown at it flawlessly.
ATRAC format CDs worked beautifully, but unfortunately the ‘Sonic Stage’ software caused a weird problem with all my mp3s on my pc and caused the volume to keep shifting up and down erratically (very strange!), but this seems to be an isolated glitch with my PC as most people have reported no problems like mine. That said the ATRAC CDs I made still sounded great even at 64kbps. But for me Mp3 playback was what I needed as 95% of my music is in mp3.
Overall, this CD player is pretty awesome if you don’t mind buying a new pair of earphones. The mp3 and Atrac CD playback is very cool especially since the price of CD-R/RWs is very cheap. If your gonna exercise with it, your fully protected with the 'G-Protection' anti-skip system. Most of the other problems were only minor flaws in the function and design of the walkman. Apart from that the only other problem for people would be the price tag of £140 which is still quite low compared to some places, like for example in Argos where it costs £170! If you want the very best in looks design and functionality, I’d recommend this but because of its price tag I would suggest you look at the Sony D-NE1 which is only £100 and is pretty much identical to the D-NE10 in terms of functionality. Also, there have been alot of good reviews about the I-River iMP-550&450 models which are top quality portable mp3 players.
