They won't warrant any noise complaints, but these six-inch, handmade bookshelf speakers boast quick connectivity and the best size-to-sound ratio of any AirPlay model we tested. While the NS2s might not produce as refined audio as the others, the three-inch Kevlar woofers and three-quarter-inch tweeters in each rubber-coated cabinet churn out solid, clear stereo sound for small rooms or offices. Available in six colors. [$450; nocs.se]
