Just posting here to give a 10/10 to Custom Art with regard to their service and product of custom tips.
A brief review of my recent experience:
I sent moulds of my ear impressions a few weeks ago to Custom Art and ordered some custom tips to fit my Campfire Andromeda (this in itself I see as admiral - not afraid to supply tips to other manufacturers products!)
I received my custom tips a few days back, packaged well, along with return of my impressions which I wanted back to send off to another company that makes custom earplugs to block out my partner's snoring
The reason I ordered these were for comfort as I suffered aching from Campfire's stock tips when listening for periods longer than around 45 minutes.
The tips provided by Custom Art are a solid yet softish silicon, very well made and fit perfectly (obviously people will need to follow advice when getting impressions made), and I quickly forget that they are inserted as they are extremely comfortable. They have taken me a little while to suss how to insert but I'm now getting the hang of it.
Isolation is excellent, and I've been told by people sitting next to me that they can't hear any sound leaking, even when I've had them on at high volume.
When ordering my only concern was regarding a change in sound signature. But I needn't have had any concern.
I have carried out A/B/C testing - Custom Art custom tips / Campfire foam / Campfire silicon
listening to:
Queen - Bohemian Rhapsody
Genesis - The Cinema Show
Talking Heads - Burning Down The House
Swans Way - When The Wild Calls
Gary Numan - My Name Is Ruin
Toto - Rosanna
Putting aside comfort (which obviously the custom tips win hands down), to me on the Andromeda (using WM1Z as the source) the custom tips rank also best soundwise, followed by the foam and then silicon. The silicon feels shouty at times (e.g. Toto - Rosanna 1 min + in), whereas foam and custom were very close in sound signature however the custom tips seemed to have a slight bit more detail (noticed on Genesis - Cinema Show).
Overall, I am delighted with these custom tips, and delighted with the friendly service received from Kamil and Piotr - a big thumbs up
and my thanks to you
