Can anyone who has had this done please in the UK please let me know what problems they've had if any. I'm still thinking of asking ACS to make some custom sleeves for my UM3x. They are no longer listed as suitable. After e-mailing them I got this response:
The reason why we have discontinued a few ranges of the headphones is due to customer complaints and fit issues, although they work very well for you, its hard to try and get the sleeves right on the Westone models.
The have a straight tip which make the sleeves hard to stay on, the modular itself sits at a strange position in the ear and can be very hard to mould off and as it is a big modular monitors its also hard to get the silicon to shape around it.
So due to time and cost of remake we have chosen to discontinue all Westone range.
I hope this information helps with your understanding on why we have done this, if you have any more questions please do not hesitate to get in touch.
Customer Service Agent
I would be grateful for any information please.
