A helpful and responsive company.
The Headphone cables arrived quickly and they were of a high quality.
This was a replacement cable for my Moondrop Cosmo H/Phones. I didn't like the look and feel of the Moondrop cable.
What surprised me was that the Custom Cans cable makes the headphones sound a lot better. The sound is fuller, but still crisp and clear. I don't have golden ears so this is quite something.
The cable is tangle resistant and it's relaxed / soft rather than lively. Nice colour too. All in all they are very nice indeed regarding quality and finish. They look and feel good.
One negative is that their website really needs a bit of work. It is difficult to pick a particular cable and then choose what goes on each end. To buy this standard headphone cable I had to work through a list of different headphones until I found one which used a cable like the Moondrop.
I've put two orders in and each time I had to telephone Custom Cans because I could not be confident that I was getting the right item using their website.
I cannot recommend this company and their products enough.
Dec 2025 I now have my second shipment from Custom Cans - Another Headphone cable and and extension cable.
The 5 meter extension cable is phenomenal. Soft tangle free cable, red to warn people of the trip hazard and it sounds incredible. No discernible sound deterioration whatsoever. Their cables deliver v e r y good sound and they are beatifuly made with excellent high quality fittings.

The 3D Printed HiFiMan Edition XS Super Grills is a nice addition to my set of cans. The grills did change the sound to be noticeably different. It really gives it an airy sound to it, but the upper-mids/highs seems sharper. I did eq the headphones a bit to give it a little bass boost, and that is with using the Schiit vali 3 with a GE 5670 5-star black plate tube installed. Some reviewers mentioned on subreddit that the grills creates a bigger soundstage to the cans, but I think it really is just the open grills providing more air inbetween the sound.
Overall, the airy tone gives it a "natural" sound to it, similar but not the same as the Hifiman Organic Arya. I think if anyone wants a natural sound for the Edition XS then this should be a considered option for those that can't or currently cannot upgrade from their Edition XS.
P.S. If anyone is afraid of buying this because of the installation don't worry, the owner of Custom Cans provides an easy to understand video to install the grills. The title of the vid on Youtube is called,
"Re-Tune the HiFiMan Edition XS to sound more like the Arya organic with our new supergrills." by Custom Cans.

I received a phone call from Customer Cans informing me that my custom cable had been made and would be posted out. They then informed me that the cable they had made had some issues. Apparently the machine they stich the silk cover broke and the technician wasn't happy with the finush. Because I had waited a while they said they would sent it out tgen at least I had a cable for my new headphones. Once the machine had been repaired they would send out a better finished cable.... True to there word that
My first purchase from Custom Cans..
The Singled Ended Ultimate Cables. Our ultimate range of headphone cables; designed be not only electrically perfect but also to look and feel truly high end..
I received a phone call from Customer Cans letting me know that my custom cable had been made and was ready to be posted. They then explained that there had been an issue: the machine used to stitch the silk cover had broken, and the technician wasn’t happy with the finish. Since I had been waiting a while, they offered to send the cable anyway so I’d at least have something to use with my new headphones. They also promised that once the machine was repaired, they would send out a better-finished replacement.
True to their word, that’s exactly what they did. Today I received the replacement, and it is absolutely perfect. The cable is excellent quality—detailed, with great bass resolution and perfect highs. It matches my Meze Empyrean headphones beautifully.
Brilliant work from Custom Cans: wonderful customer service, genuine honesty, and a fantastic product. You can’t beat that—I highly recommend them.
I'm a regular customer of Custom Cans and come to them every month or 2 to buy custom pieces off them for all my sennheiser hd25 builds, I cannot recommend them enough!

After replacing the original dampers with Custom Cans filters, my HIFIMAN Sundara truly came alive. The sound gained openness, clarity, and a wonderful sense of flow — it now feels effortless and full of life. Instruments breathe naturally, the bass is more controlled, and the whole presentation feels like listening to high-end speakers. Absolutely stunning upgrade — the best my Sundaras have ever sounded! 🎶🔥

I’ve now purchased three separate headphone cables from Custom Cans.
Most cables that are supplied with headphones (Even high-end ones) are either too long / short / stiff / heavy for your particular headphone and amp setup. Enter Custom Cans - you specify your connectors, length and even colour combinations, and they deliver you the perfect cable every time.
They even provide a service to change the connectors on their cables should you buy a different brand of headphone and don’t want to bin your current cable.
One very satisfied customer 👍
