Old Lyme, CT (September 6, 2018)—Sennheiser has announced the IE Pro Series of professional dynamic in-ear monitors, debuting later this month with the IE 40 Pro entry-level model, to be followed in early 2019 by the IE 400 Pro and the top-of-the-range IE 500 Pro.
Available in black and transparent versions, the IE 40 Pro is built around a Sennheiser driver reportedly offering low distortion (0.1 percent at 1 kHz and 94 dB), and neodymium magnets helping provide an SPL of up to 115 dB.
The IE 40 Pro mechanical design includes a patent-pending cable ducting that is said to reduce the risk of cable breaks. The connector is accommodated inside the ear mold, where it sits protected against the wear and tear that occurs during heavy use.
The IEMs are said to be able to reduce ambient sound by up to 26 dB, and come with a choice of included silicone ear tips (S, M, L) and a special ear tip made from memory foam, which expands to fit the ear canal. As the length of the human ear canal varies, the earphones’ ‘sound tunnel’ has two rest positions to attach the ear tips to, heling ensure sealing.
The IE 40 Pro comes with a soft storage pouch, a cleaning tool and silicone ear tips in three sizes (S, M, L) and a pair of memory foam ear tips in size M.
