Do not buy any Shure products from this company, no warranty. I have send my high end Shure SE846 Professional Sound Isolating Earphones for repair for a minor fault to E-Infinity, when it was returned to me the earpiece literally fell apart. E-Infinity told me that I would need to send it back to them for further repairs. Instead I contacted Shure Customer service and they informed me that they have received several complaints about E-Infinity and any product bought from them is NOT covered by Shure warranty. Also E-Infinity refused to provide me any information and internal communication about my repair even after I quoted GDPR guidelines. I will be starting a small claims court procedure because E-Infinity provided me an unauthorized product and destroyed my Shure SE846.
