So the Sony Ericsson W715 is currently the newest member of Walkman series of Sony Ericsson. As expected, the most important thing about a W715 Walkman handset is definitely the music capabilities of the Sony Ericsson W715. So let’s talk about it then 
The very first I noticed about the new Sony Ericsson W715 is the lack of standard 3.5mm headphone socket, which is something that I expected a music phone to have. Too bad, really… However, there is a 3.5mm adaptor wire that also features a built-in microphone for making and receiving calls.
Next stop; the Sony Ericsson W715 headphone. Compared to most included headphone on the market, the W715 headphone have a superior quality. It got a warm, powerful sound, with some passive noise-canceling. Moreover, you’ll also get three different ear buds and you can choose which one suits you the most.
Wireless/Bluetooth listening? No problemo. The Sony Ericsson W715 also features Bluetooth A2DP for those who want to listen to their music with a set of stereo Bluetooth headphones.
Now let’s talk about the W715 music player. The Sony Ericsson W715 features ‘Walkman Player 3.0′ with motion-sensitive controls. So basically all you have to do is press the Walkman button on the top of the phone to activate the Walkman Player application. After the player is on, you can create playlist and browse music by artist, album, track, playlist, genre, and year. Moreover, the Sony Ericsson W715 Walkman also creates its own playlists for your most played songs, not played songs, and newly added songs. Moreover, there’s an 9 preset options equalizer to improve the quality of the music. In addition there are also album art and visualizations
So what are additional goodies related to Sony Ericsson W715 Walkman? Well the spotlight goes to Sony Ericsson’s ‘TrackID’ software and ‘MusicDJ’ application. The MusicDJ allows you to play around with different instrument sounds to create your own songs.
What about the Sony Ericsson W715’s storage? In order to keep your list of favorite songs in this Walkman phone, Sony Ericsson have put 120MB of built-in storage memory. And if that’s not enough, the W715 can handle M2 cards up to 8GB in capacity. Pretty big
Overall Conclusion (Including other Features):
The Sony Ericsson W715 is a very pleasant device to use, and gave me no real problems when using it, aside from the occasional occurrence of a flashing red light from behind the keypad, which required removal of the battery to stop it. Aside from this, the device performed flawlessly throughout our testing, and I found very little to complain about. Sure, the screen is a bit small for web browsing, and the camera’s lack of autofocus and a decent flash was disappointing, but this device is designed for music, so these additional features are merely icing on the cake. The only real worry for this phone is the lack of a 3.5mm audio port, as many non-music specific handsets even have them these days, so the W715 definitely should. Still, even this isn’t a huge problem, and is easily overcome with the included adaptor.
The W715 does its main task very well, providing a great audio experience with some added GPS services as a bonus. It’s a very nice package overall, and the high quality materials used in its construction give it a robust, expensive feel. It does all the basics well, and the battery life was very good throughout our testing, despite some extensive testing of the phone’s features. I was also quite surprised at the number of handy and entertaining extras included on the handset, such as the music quiz game, the TrackID application, and the training tracker.
Overall, I give the Sony Ericsson W715 a “Highly Recommended” rating, as it’s a great music phone, and has very few faults to speak of. You’ll find a selection of photos taken with the W715 on the following page.
