Audio
Call quality on the K750i is quite good. The phone's speakerphone is housed beneath the rear panel camera assembly, rendering it basically invisible, but callers' voices still came through acceptably loud and clear. The speaker also works surprisingly well as a makeshift way to share your music with others. It won't take the place of a stereo system by a long shot, but it works fine when you need a quick music fix.
The included stereo headset functions well for calls and music playback. As mentioned above, a 3.5mm adapter is available for using the phone with any standard stereo headphones of your choice. Sony Ericsson should have built the phone with an integrated 3.5mm (or 2.5mm, anyway) audio jack, instead. While the included headset is fine, switching to a quality pair of stereo phones or connecting powered speakers really makes the K750i a serious music device; audio playback from high-quality music files approaches iPod quality. A stock K750i upgraded with the 3.5mm adapter and a larger Memory Stick means you can leave your mp3 player at home on most days.
SE seems to have a thing for proprietary connectors on their phones, and I must say it's rather annoying. The sole multi-connector port on the K750i can only be used for one thing at a time, and as its the place where both the headset and charger plug in, this means that the phone can't be used with headphones while charging. While not a deal-breaker, this does bring up some potentially annoying situations, say wanting to listen to music through headphones (or a car stereo adapter) when the battery is running low — using a headset and charging the phone shouldn't be mutually exclusive.
Support for Bluetooth headsets is included, and works very well with both Sony and third-party devices.
