That’s strange because the serial number on my case and certificate is 35xx and the production date is 01/04/21 (01 April 21).

This serial number has got me concerned. Does anyone know what the serial numbers should be on the legit IE900 from April 2021? jromee’s serial is 18xx yet it was produced over 6 weeks after mine which has the serial 35xx. I smell a rat.

Searched Google images and YouTube unboxings for serial numbers. +/_ 1700 from april.. From my calculations they made like 400 pieces a month back then.

I am going to return the IE900 back to CEX because the serial number is dodgy. No way should the serial number be 35xx if produced on 1 April 2021. All of the unboxing I’ve watched have revealed that the serial numbers from 1 April 2021 are 12xx onwards and not 35xx like on my IE900.

I went back to CEX with the IE900 and told them that I suspect that I bought a counterfeit IE900. They then took them to the back of the shop amd returned back 20 minutes later telling me that they think the case maybe fake but they are 90% sure that the IE900 are real amd that they cannot give me a full refund. Instead they said they can exchange me vouchers to the sum of £700. I refused demanding a full refund but to no avail. They told me to wait for the email from Sennheiser about the serial number being 35xx from 1 April 2021 when they serial should be in the 10xx to prove if they are actually counterfeits.

That sucks. Any chance you purchased with a credit card or the like where you can dispute the transaction?

Either way, let us know how it goes. Wishing you good luck with this!

I purchased using a debit card. However, I don’t know how to dispute a transaction.

I have no luck with those Sennheiser IE IEMs. I remember over 12 years ago purchasing Sennheiser IE 800 IEMs from my local pawnbroker which turned out to be counterfeit but atleast when I took them back they gave me a full refund back into my bank account unlike CEX who will only refund with store vouchers.

Anyway, I’m still waiting for a reply from Sennheiser support.

Just call the number on the back of the card and tell the story and see if they can help you out. I have done this before (in the US) and got my money back.

Also, I found this online. How long has it been since you purchased. I would consider counterfeit as a fault?

I purchased a pair of i.e. 900's from Ebay and contacted Sennheiser. They said the following serial number on the case was not in their database: 003706. Has anyone owned these for a few years with reliable performance? The mmcx connectors seemed laughably fragile. Offhand, and very peculiarly, these sounded absolutely sublime and somewhat boring to me. Sennheiser also said they would not repair them but only exchange them. Has anyone paid to have the mmcx connections repaired?

I purchased the IE900 IEMs yesterday. When I took them back today they told me they could give me CEX store vouchers to the sum of £700 since I’m still in the 48 hour unwanted return policy. However, I refused and wanted a full refund in my bank account instead but they couldn’t do it. Unfortunately the card enquiry number at the back of my debit card is a 0845 number which charges me.

They told me I would have to have confirmation from Sennheiser that the serial is counterfeit then they would look into giving me a full refund back into my account.

You’re right that counterfeit items should be classed as faulty but they don’t see it that way. They extended the 48 hour unwanted item return policy for 2 weeks so it gives me time for Sennheiser to get in touch with me about the serial numbers but it’s only vouchers. I don’t know if I should just get the vouchers instead as I buy a lot from CEX.

That is very interesting and shocking. I will probably get the same response from Sennheiser whenever they reply which means there is no reason for CEX to refuse to refund me in full into my bank account because a serial number not being in Sennheiser’s database mean they are 100% counterfeit.

The moral of the story is if it seems too cheap to be true then it probably is.

The lesson is only buy from a Sennheiser approved seller or someone you really trust, I wouldn't even buy second-hand from a seller here on head-fi to be honest and definitely not CEX or ebay.

True but still I don’t see £700 as cheap as they were more or less selling half price from CEX and I’ve bought items before from CEX which were half the price and never had bother. Due to counterfeits I guess when it comes to expensive headphones and earphones from the likes of Sony and Sennneiser I’d be better to buy from them direct or shops who are authorised sellers of Sony or Sennneiser. Never again will I buy expensive. Ranked IEMs secondhand again. I should learnt from my first experience. Hindsight is a great thing.

I went back again to CEX and eventually managed to return them and get a full refund back on my debit card. What a carry on it was as I was in the store for an hour. They compared photos of the box contents of other IE900 IEMs from other branches and they looked different but they were still baffled and decided just to give me a full refund.
