Hey everyone!
Ear tips and comfort are key to in-ear wearing comfort and forming a good seal for isolation and bass response. To help in this regard, Sennheiser includes tips in foam and silicone, in three sizes each, and each tip can be used in two positions!
Sennheiser just released this illustration to better demonstrate the two positions and insertion depth options on the included ear tips:
As you can see, the tips can be pushed all the way down over the nozzle for a shallow insertion depth, or the tip pulled out to reveal some of the stem of the nozzle and to have the ear tip extend deeper into the ear. The tips hold these two positions by having two grooves in both the silicone and the foam tips, as shown here:
The sound and comfort will vary based on an individual’s ear shape, where the first bend of their ear canal is, and personal preference. We encourage all users to experiment!
