SpinFit OMNI vs final Type E
Which should you buy? Our verdict on both, pulled from our full The Best Replacement Earbud Tips: 4 Compared (and One to Skip) comparison.
The OMNI answers the compatibility question with a number, a nozzle range of 4.0 to 5.5 mm, and offers six sizes for both true wireless earbuds and IEMs. The final Type E gets you most of the way there for less, if you are willing to test the fit rather than check a specification.
SpinFit OMNI
Buy itPublishes its nozzle fit in millimetres, 4.0 to 5.5 mm, and comes in six sizes that suit both true wireless earbuds and wired IEMs.
- SpinFit states the fit range plainly: nozzles of 4.0 to 5.5 mm, and the product page adds that the tip can stretch a little beyond that.
- Six sizes, SS, S, MS, M, L and XL, and SpinFit prints the dimensions of each one so you can compare them with your current tips.
- The core swivels, which SpinFit describes as its patented design, letting the tip follow a canal that bends.
- SpinFit publishes no replacement interval on the product page, so you are judging wear by feel rather than by a schedule.
- Silicone seals but does not damp, so it blocks less outside noise than foam of the same size.
- No thin-nozzle inserts are listed, so earphones with tubes well under 4 mm need a different tip.
final Type E
Buy itFive sizes of two-hardness silicone, with a case and a thin-nozzle adapter in the box, from a maker that explains on its own product page why the seal changes the bass.
- Five sizes, SS to LL, with the stem colour stepping through the range so a mismatched pair is obvious at a glance.
- final uses a harder grooved silicone for the stem and a softer grade for the dome, so it grips the nozzle without pressing on the canal.
- A carrying case and an adapter for earphones with thin sound tubes are both included.
- final does not publish a nozzle diameter range in millimetres, so on an unusual earphone you are testing rather than checking.
- Silicone gives you less isolation than foam, which shows up on a train or a plane.
- The two-colour left and right stem applies only to the black version.
