Sony Ericsson K750 review
This is located at the back of the handset and has quite a clever design feature. The speaker used has RMQ (rebound magnification quality) technology. This is something SE used on the S700i but seems to work better on the K750i. If you place the device on a flat solid surface, you would assume that because the speaker is at the back of the phone, it muffles the sound and hence decreases the volume. This is quite the opposite, as the volume sound is magnified when placed on such surfaces. It is only if you put the handset on a bed or a soft surface that the sound level is reduced. This is a good function when listening to music through the loudspeaker. Voice calls are also at a reasonable level through this speaker, although I know there are some other handsets that boast a much louder sound; something you can still hear with much background noise. All in all, I think the loud speaker is still an improvement from previous SE models.
The file manager has also been revamped and improved. You can now successfully organise your various file types between your phone and memory stick. The folders are pre set to pictures, video, sounds, themes, web pages, games, applications and other. Whenever you receive a new file, it is automatically saved into its corresponding location depending on the file type (e.g. a new image is saved into the pictures folder). You can't add to these folders, but in all honesty they cover pretty much everything you'd need. You can however create your own sub folders within these pre-defined folders to give you more storage flexibility. When viewing pictures, you can also display them in a slide show' which will automatically scroll to the next picture like an electronic gallery useful if you want to browse though a lot of images without manually having to keep pressing the joystick. Supported image formats are: GIF, JPEG, WBMP and BMP.
The other' folder will store anything you receive whose format is not recognised by the device e.g. Microsoft word file. Even though you can't open these or similar file types, you can still send them to another device using infrared, bluetooth or even as an attachment via email and this gives the K750i some useful storage capabilities.
