Review: Sonomax Eers custom-fitted earbuds

The process is a little unsettling, because you will feel this bladder slowly filling you ear. You have to sit still and not talk for 5 minutes, and in that process the sounds of the outside world will slowly disappear as the bladder fills. By the time you are finished, most external sounds are gone, and you are left with a set of custom fitted earbuds. The device that did the injections is disposable, so just disconnect your earbuds and throw it away.

But are they good earbuds?

The Sonomax Eers SD250 are a dual driver setup and capable of delivering a wide range. Compared to a set of Klipsch X10i’s, Eers lean a little more on bass, but are still capable of delivering a cleaner sound when delivering high notes or instrumental sounds. Eers are capable of delivering a high quality audio experience both for the bass-heavy consumer and for the concert violin fan.

Unlike most headphones, the sound from Eers don’t get harsh or grainy when the volume is up. During an interview, one of the Sonomax audio engineers explained that this is the result of the custom molding to your ears — because of the seal that is created by the molding, and because the earbuds are closer to your eardrums than most traditional buds so the Eers are actually quieter than a comparable set of earbuds without custom molding. Compared to my standby Klispsch x10i earbuds, the Eers are a much better audio experience.

My only real complaint about the Eers is the cable. In a world where even $20 earbuds and headphones are starting to come with braided cables, it was disappointing to find the plain grey rubber coating on a set of $299 earbuds. It is very clear that the bulk of the technology is in the earbuds and the custom molding, but when all of that is done you still have a set of earbuds with a cable that easily tangles and does not feel very high quality in the hand.

Final Thoughts

For $299, Eers are not going to be flying off the shelves. Even their single driver brother, which clocks in at $199, is still too rich for most people’s blood when it comes to a set of earbuds. Eers are for someone who has probably already spent $200 looking for a set of earbuds that they are truly comfortable with. Because they are custom molded, Eers stay in your ears naturally and comfortably. Even in an overnight test, I woke up the next morning and the Eers didn’t bother me to use. They are just as good for long flights as they are for jogging, and there are not many earbuds that can claim that.
