I recently purchased a pair of custom-made eA-R earpieces, and I wanted to write down some of my impressions after using them.
Taking Ear Impressions
I found a hearing aid shop in Shinsaibashi that was familiar with taking ear impressions specifically for eA-R products, so I had my impressions made there.In my case, I felt a little pain when the impressions were removed from my ears. I imagine this varies depending on the shape of each person’s ears, but it may be worth keeping in mind if you are considering having ear impressions taken.
Getting the Fit Right
For me, putting the earpieces in properly took a little practice.After inserting them into my ears, I twist them slightly until they lock into place. They feel very securely fitted inside my ears, although this also creates a slight sense of pressure.
Because of that, I personally would not want to wear them continuously all day. I do not use them for live performances, but judging from how securely they stay in place, I imagine there would be very little chance of the earphones becoming loose or falling out during a performance.
Bass
I use the eA-R earpieces with Sennheiser IE 100 PRO in-ear monitors.Once they are properly fitted and sealed in my ears, the amount of bass they produce is greater than I had expected.
At the moment, I also use beyerdynamic DT 250 headphones when checking my masters. Interestingly, there are times when the IE 100 PRO with the eA-R earpieces makes it easier for me to notice when I have added too much bass to a mix.
As a result, they have given me another useful monitoring option when checking both mixes and masters.
Treble
With the standard eartips supplied with the IE 100 PRO, I sometimes felt that the treble was slightly emphasized.After switching to the eA-R earpieces, the bass became much more present, and as a result, the overall balance between the low and high frequencies feels more natural to me.
Rather than the treble itself changing dramatically, my impression is that the improved bass response has changed the overall tonal balance.
Everyone’s Ears Are Different
Everyone’s ears are shaped differently.Going through the process of having ear impressions taken and trying the eA-R earpieces also made me realize that my own ears have certain characteristics that I had never really thought about before.
Of course, I do not expect my experience to apply to everyone who is considering custom-made earpieces.
These are simply my personal impressions, but I hope they may be useful to someone who is thinking about trying custom earpieces for themselves.
