M3 True Wireless 3 GraphiteSH-M3-TW3-GRA

This is the second pair DOA - dead on arrival. I kept it on charge for 5 hours and buds won't start. Cradle detects them but it is not powerful enough to start them...

first 2 weeks it was really good, then people couldnt hear me properly. i thought it was something to do with the IOS so i waited for an update and still it didnt improve much. Is it because i only use one ear piece to talk.. im not sure. if i keep both then you feel really immersed and cant hear much anything of the ambient noise. so for example its dangerous to keep this and walk around.. i feel. Its really impressive in sound reproduction when listening to music.. Sennheiser class. But not impressed with communication, i’ m thinking to buy the cheaper CX series for this. I have been using the brilliant Momentum free for about 6 yrs and gifted it to someone special. Is there any Sennheiser support reading this please comment/help... its not cheap so please be considerate.. so that people like me keep buying Sennheiser.

If you store the item for over 4 weeks without charging. The buds do not work. If you try to recharge it does NOT work. If you request for an invoice for the item in order to get assistance on how to fix them , you are informed there are no invoices. This product has 48 months warranty however without this invoice they are unable to assist you to get them fixed under warranty . Very disappointed

Update: Out of the box, the headphones are great per my below initial review, however, you quickly start running into quality issues with battery drain and poor overall battery life, in a little over a year, the earbuds won't turn on no matter how long you leave them to charge. Finally, they just die. You cannot do anything with them. Warranty claim are a pain in the backside. Just avoid these if you can afford other options (sony/bose), the quality issues are too common and highly likely. The earphones are great. The build quality, sound clarity, separation, noise cancellation, fit and transparency and all great. BUT be mindful of what you’re buying, they aren’t the loudest, bassiest or ANC beasts. I’d say their strength lies in separation, you can hear every tick and instrument and if these are the things you’re looking for, they’re right for you

The right earbud stopped working within a year. This is the second time this same issue is happening after having it replaced already. And I forgot to purchase the extended warranty now and no base warranty or support provided on amazon. What now? Edit: I mailed Sennheiser and got it replaced from their closest distributor. I had to drive there. Can get it replaced as long as it's under warranty. 2 years from date is purchase.

Product stopped working after 5 months and no base warranty provided

These very expensive earbuds have a serious issue with charging. Especially if you dont use the device for some time you can forget the idea of ever charging the buds again, they will simply not receive charge. There are a number of 'hacks' and 'tricks' to get them working, but I didn't buy a cheap set from some dodgy website to be meddling with them for something so basic, I forked out for a premium set of buds only to have them fail so miserably. Think twice before buying Sennheiser, plenty of other more reliable brands out there that are made with better quality standards.
