20 pcs Phonak Open 4.0 Dome Medium (0.39 inch = 10mm) by Lillu, Replacement Open Fit Ear Tips for Phonak Audeo Marvel, Paradise, Lumity, Sphere & Costco KS10 Hearing Aids

• OPEN 4.0 DOME, SIZE MEDIUM (0.39 INCH = 10 MM): Medium dome matching the Phonak 4.0 open dome profile. Dome sizes are not interchangeable, so check the dome currently on your receiver before ordering. Lillu also offers this dome in Small and Large
• FITS PHONAK RIC AND RIE HEARING AIDS: Compatible with Phonak Audeo Marvel, Paradise, Lumity and Sphere receivers, and with Unitron Discover Next (DX), Audicus, Hansaton and Costco Kirkland Signature KS9, KS10 and KS11 hearing aids. Lillu is an independent hearing aid accessory brand and is not manufactured by, sold by or affiliated with Sonova or Phonak
• OPEN DESIGN KEEPS YOUR OWN VOICE SOUNDING NATURAL: The open structure lets low-frequency sound pass through the ear canal instead of sealing it shut. That reduces the plugged-up occlusion feeling and the hollow echo many wearers notice with closed domes over a long day of wear
• 20 DOMES PER PACK: Each order includes 1 pack with 20 domes total. Hearing care professionals commonly advise changing domes about once a month so earwax and moisture do not dull the sound
• SOFT SILICONE, CHANGES IN SECONDS: Flexible soft silicone that pushes straight onto the receiver, no tools required. Not recommended for anyone with a perforated eardrum or an active ear infection. Ask your audiologist before switching dome type or size, as it changes your fitting
