The ParMarLow ES-RUB earphone from TWITCO is designed similarly to the ES-MUR earphone, but with a soft rubber-like housing. This allows for a more secure and comfortable fit on even the smallest of ears. Like all ParMarLow earphones, the ES-RUB is available in cable lengths of 39 and 18 inches and either a 2.55mm or 3.5mm phone plug. A 3.5mm threaded plug version with 39 inches of cable is also available.
The Compression Carrier naturally flexes to the contours of the body for greater maneuverability and maximum concealability while the thermoregulating inner lining provides a cool, comfortable fit.
