The £20 price difference is very evident in these two products. The Altec Lansings look more expensive than the Labtecs and have luxuries like push-button volume controls and a bigger sub-woofer. On the audio front, the Altec Lansings are slightly woolly, but deliver a loud, easy to listen to sound. The Labtecs, on the other hand, are completely different, with less bass and a more detailed treble, and that sense of spaciousness which is missing from the Altec Lansings. If you prefer a thumping mellow sound, the £20 extra would definitely be worth it for the Altec Lansings. Otherwise, the Labtecs are worth the money.
