Intro.

I never heard of the Canpur IEMs brand until CanJam SoCal ’23 when their full catalog appeared on the Musicteck website right before the show.  It got me curious, especially when several people told me I must check these out.  Since I only attend CanJam NYC, I couldn’t wait that long and requested to hear them after the SoCal show.  If I’m not mistaken, the company is from the EU, but their webpage doesn’t have too much info thus I don’t know exactly the history behind these IEMs.

Nevertheless, these Canpur IEMs generated quite a buzz last year and many audiophiles are still talking about it, which suggests it was not just another flavor-of-the-month release.  I did cover their CP622B and CP54E models in my CanJam SoCal ’23 report (based on the samples I borrowed from MT), but that was just a brief write-up.  Recently, I had the opportunity to spend more time with the CP622B model and would like to share my in-depth analysis of these flagship IEMs from Canpur.

Unboxing and Accessories.

CP622B (622B) arrived in a black leather box inside another cardboard box with “Canpur” printed in gold across the top.  The packaging was premium and appropriate for the flagship model along with a handful of quality accessories, such as a custom rectangular leather storage case with plenty of room for IEMs, thicker upgrade cable, extra eartips, and a cleaning tool (included).

You also get a leather display stand to showcase your 622B.  With a kickstand on the back to keep it upright, it has corner pockets and nozzle cutouts at the top for the shells, and a spool to wind a cable at the bottom.  Included was also a travel organizer box with eartips, two sets in S/M/L sizes, one smoky grey with thicker silicone caps, and another white with softer silicone caps.  These reminded me of Acoustune AET07 eartips design.

Cable.

The included cable is the brand name Eletech Socrates copper cable, a monocrystal bespoke cryogenically treated OCC Copper, 24 AWG gauge with 7N purity.  With this cable, Eletech developed in-house geometry stranding to maximize the design efficiency which allows various multiple-sized strands of copper to be encapsulated within their own FlexiMax insulation, keeping the cable slim, flexible, and microphonics-free.  Furthermore, it is Kevlar infused for extra durability, and Eletech also uses a premium grade bespoke solder.

The main part of the cable between the plug and y-split has 4 loosely braided wires, and above the split, wires are twisted in two pairs going to the left/right 2pin connectors with black metal housing, L/R marking on inside and ET symbol on the outside.  The cable features a pre-shaped ear hook in the form of a clear heat shrink for a comfortable fit over your ears.  The only thing missing here is a chin slider.  Btw, while this is an original Eletech design, the manufacturing of the y-split and the plug was done by Pentaconn.

Design.

The naming of Canpur IEMs is based on the number and the type of drivers used in each monitor.  Here, the CP stands for Canpur Performance series, and in CP622B the numbers/suffix refers to 6BA drivers, 2EST drivers, and 2BC drivers.  Then, for example, CP54E stands for the Canpur Performance series with 5BA and 4EST drivers.  The 622B 10-driver tribrid design, with a spec of 10ohm Impedance and 100dB Sensitivity, uses all Sonion drivers with a breakdown of:

• Sonion 38D2XJ007Mi-8c – dual bass sub-/woofer
• Sonion 28UAP01 – dual med/low-frequency drivers
• Sonion E50DT0005/D – dual tweeters
• Sonion EST65DB02 – dual EST tweeters
• Sonion 37AAX007 – dual bone conduction vibrators

622B IEMs black acrylic shells come with a nice-looking faceplate design and a “Canpur” name in silver on each side.  The tip of the nozzle has a mesh cover to keep earwax away from the drivers.  The inner side of the shell is sculptured and slightly bulbous to pack all the drivers under the hood, including 2x Bone Conduction drivers that require more surface contact.  Depending on the anatomy of your ears, especially the concha cavum area, for some, it could create a bit of discomfort if you have smaller ears.  However, I found a very effective solution that worked for me by rotating the shells slightly forward to align better with my inner ear.

The fit.

As you can see, the forward rotation angle is very small, but it makes a big difference in comfort as you adjust the shell to fit your ears better.

Sorry, these selfies turned out to be slightly out of focus.
