The Sennheiser CX300-II Precision in-ear earphones extend upon the legacy of the highly successful original CX300 models by improving fit ergonomics and delivering slightly clearer overall sound. Comfortable, non-invasive ear canal fit affords mild isolation and an easy wearing experience even for in-ear newcomers. They're ideal earphones for remaining aware of your surroundings while listening -- provided you're not turned up too loud!
What We Think:
The German headphone giant makes its powerful presence felt in the highly competitive 'under $50' in-ear category with the Sennheiser CX300-II Precision earphones. The CX300-II fit style could almost be considered a hybrid design somewhere between a shallow-fit earbud and the deeper insertion characteristics of a true in-ear monitor [IEM]. The CX300-II sound quality is certainly better than most earbuds but probably not quite up to par with significantly more costly in-ear headphones over $79, but their overall sound quality performance remains quite close at a friendlier price. The isolation factor certainly won't match that of an IEM either, but the CX300-II still provides decent external noise-blocking equal to many non-'noise-cancelling' sealed on-ear headphones. The mild isolation level is ideal for listeners intent on remaining aware of their surroundings.The Sennheiser CX300-II Precision's mids & highs are clear-sounding, but not brightly extended in the uppermost highs which is smoothly rolled-off. The bass presence seems to be significantly affected by the user's choice of eartip and, of course, the overall tightness of the earpiece's fit within the ear canal; given the right tip fit, expect a punchy full-sounding bottom-end response. The CX300-II occupies a unique niche between earbud and in-ear headphones and is a very nice initial step especially well-suited for in-ear earphone newcomers wanting better headphones than the stock buds found with your portable player device. The Sennheiser CX300-II Precision earphones come with black silicon eartip sleeves sized small/medium/large. Try them all and select for the best sound quality and most comfortable fit. The inconspicuous matte-black color scheme of the CX300 earpieces and cabling resists showing dirt and looks pretty slick to boot. Highly efficient operation and a low 16-ohm impedance rating ensures plenty of output from any mobile audio source like iPods, iPads, Kindle readers, MP3 / DVD players, laptops, and portable gamers. The asymmetrical 'J' cable style minimizes cord slack on the move when hooked up to a portable device on your belt or armstrap. The 4.5' cable is terminated to a mini-plug 1/8' (3.5mm) termination. A strong 2-year product warranty remains standard on all Sennheiser products.
