MandarinEs Symbio F Eartips

Symbio F is the all-foam version. For the foam/silicone version, please see Symbio W.

Symbio F Eartips from MandarinEs are an incredible product which offer unprecedented isolation and superior sound quality compared to more traditional eartip replacements. No more seal problems caused by shallow ear insertion, supreme comfort, and the superb longevity of memory foam and silicone.

The thermoplastic memory-foam inner core of the Symbio W reacts to the warmth of your ear, gently moulding into the ear canal. Unlike other foam tips, your treble extension is not compromised and the bass remains intact, without being boomy.

Unlike the W version, Symbio F has a FOAM outer, not silcone, for those who may be allergic to silicone products. This foam outer means that the tips are durable, easy to fit, and create an amazing seal that remains comfortable even after prolonged listening sessions or active pursuits.

Inner Bore Sizes

The standard Symbio F has an inner bore diameter of 4.5mm, which fits the stem & nozzle of most earphones. The Symbio FN and the Symbio FA versions are supplied with extra inner adaptors, which reduce the bore size to 3mm-4mm (Adaptor N), and 2mm-2.5mm (Adaptor A) respectively.

This flexibility ensures a perfect fit for almost all earphones on the market, including Apple Airpod Pro, Senneheiser True Wireless, Shure SE846 and the entire Shure SE series, Westone UM Pro 50, and all In-Ear Monitors with stem diameters between 2mm - 4.5mm.

Outer Eartip Sizes

All bore sizes are available in three different eartip diameters (Small, Medium, Large), ensuring the perfect fit for any size ear canal.

  • Small size is 11mm diameter, and is supplied in a pack of x3 pairs.
  • Medium size is 12.59mm diameter, and is supplied in a pack of x3 pairs.
  • Large size is 14mm diameter, and is supplied in pack of x3 pairs.

If you are unsure of your ear canal size, we also supply a pack of mixed sizes, comprising x1 pair each of Small, Medium and Large sizes.
