At 10 grams, the Sennheiser CX 1.00 ear canal headphones are easily the lightest pair of headphones in the Sennheiser range, even lighter than the CX 3.00, CX 5.00G, PMX 686G and OCX 686G!
The the Sennheiser CX 1.00 earphones are small and unobtrusive, delivering well-balanced punchy sound with crisp mids and highs and decent lows.
Being in-ear canal headphones, you always want these type of earphones to be comfy and the Sennheiser CX 1.00 sit nicely inside your ear canals thanks to comfortable ear tips.
The connector type on the Sennheiser CX 1.00 is a standard 3.5mm low profile angled plug attached to a 1.2m long symmetrical cable.
The 2 year warranty from Sennheiser is great as it means should anything go wrong with the earphones you'll be able to get them replaced.
