Philips brand licensee TP Vision has announced a set of earphones specifically designed to be used while sleeping. The N7808 sleep headphones with Kokoon have been designed specifically to be worn during sleep and the in-ear monitors (IEMs) have been designed to be as unobtrusive and comfortable as possible during sleep. Part of the reason for this, is a very compact body that is only 6 mm thick, which Philips claims is thanks to the use of balanced armature drivers and should be compared to regular earphones that often have a body with a thickness of 20 mm or or more. However, what makes the N7808's really special, is that it also features sensors that monitor your sleep pattern, that will fade out the audio as the wearer falls asleep.

The downside is that many of the sensors are placed in a compartment that rests behind your neck and this is also where the battery and Bluetooth connectivity is located. It doesn't appear to be any kind of ANC built in, as the company only mentions noise isolation. However, the heaphones are said to be inducing "intelligent" white noise that is said to masking sounds that make you wake up. The battery is said to be good for 10 hours of usage, which should be sufficient for most people. The partner app designed together with Kokoon allows the user to monitor their sleep duration, as well as the kind of sleeping state the user has attained and for how long during the night. The SN7808 is currently offered at an introductory price of US$174, with an MSRP of US$249.
