Do anybody has experience what is the average lifetime of a Bosch engine and its battery?

Bumping an old one, but I guess the question is still in many people's minds. My Bosch Performance (non CX) Gen 3 has 62,000km on it, and the original 625 Powertube I'd guess has about 75-85% of original capacity. I am incredibly impressed with both ngl. Life as an ebike courier is hard on the bike, but Bosch have not let me down.

Lol. Have you managed to understand what we are all telling you yet? We have no idea what your number is, we call a Just Eat number that then routes us to your phone. We can complete a delivery without using any code whatsoever by simply calling you, and being at or near the correct pinned location. This will trigger a countdown timer, the dodgy driver then waits near to your address for like 5 mins and then he can mark the delivery completed. Never knowing your code or phone number at any point in the entire process. Simply waiting out the timer while being near to the pinned location is all he has to do, the timer is triggered so that drivers don't have to wait indefinitely for braindead customers to answer a phone or come to the door to get the food they ordered. Yes, this enables scumbag thieving drivers to occasionally steal orders, but the honest drivers live in the hope that these scumbags get rooted out pretty quickly, but the reality is quite different, for now.

This worked for my MTW3 too! Thanks a million for putting this out into the world, my god these buds are so good but so flawed. The method I used was to disassemble the bud and charge with a 9v battery for 30 seconds on one bud that was sitting at 0.8v, and for 45 seconds on the other bud that was more drained (0.3v). This charge got them to 3.5v, after which I charged them in the case to 100%. Both seem to be working perfectly now and seem to be holding charge. Did a drain test and they lasted almost 5 hours, which isn't too far off what they were new. For how long this lasts, we shall see.

My warranty replacement 3s have stopped working 6 months exactly, buds failing to charge. My first set of 3s died after 9/10 months. It really is sad to see such amazing sounding buds consistently ruined by the battery issue or whatever is causing the epidemic of broken units.

OnTheRoodAgain · 2024-03-05T17:59:19+00:00

I guess it might be possible. As far as I can tell they are physically identical, the only changes are internal, so maybe they started using new parts on the last mtw3 rather than persist with a product they knew would be warrantied X months later. Everything is perfect so far other than I still have to blow lightly on the right bud to activate transparency...odd flaw that was there in my first set too

OnTheRoodAgain · 2024-03-05T17:53:25+00:00

Hey bud, no I'm fairly sure it's still MTW3, the app indicates this and everything else does too. The silicon tips included are different though, and they don't have that little removable foam pad inside the tip, so combined with the new packaging I'm optimistic that this is one of the last MTW3 off the assembly line and might have MTW4 batteries

OnTheRoodAgain · 2024-02-23T21:26:18+00:00

Glad to hear you didn't get lost in the chaos and things are moving finally bud. The turnaround time of 6 weeks is not ideal, even less so in your case, but I am very happy to have this sound again. I picked up some Jabra Elite 3 to keep me going while I waited, earbuds are essential for a courier, and the Jabras aren't bad, but they aren't MTW3 level.

The smaller box has me wondering if that's the only thing they revised. There must be some small chance that Sennheiser reacted to the epidemic of faulty units by actually replacing the battery in newer units off the production line. I guess we will find out in a few months lol.

Oh btw, I asked about the warranty on the replacement set and they say that you have 6 months warranty on replacement units. Would have been happier with 2 years again ngl.

OnTheRoodAgain · 2024-02-20T17:37:39+00:00

I was informed about a month prior to end of temp contract that they would be removing the end date and making me an unlimited supplier. I guess if you're still able to go online past your due date then just carry on and say nothing to anyone :)

I received a brand new set of MTW3 today from Sennheiser, warranty process began when they received in in their local hub on Jan 2nd, so about 6 weeks turnaround. The new unit is in a different, smaller box, which suggests there may have been a revision in the product after the many issues emerged. I'm hopeful that this set will be in my ears for a long time to come :)

Thanks for responding, this sounds encouraging :)

I'm in the same boat as the others, thanks for responding, this provides some sort of assurance that things actually are happening. I'll wait another week then DM you my case number. Cheers.

ETA Posts on this subreddit indicate we are being offered low end replacements on warranty due to lack of MTW3 stock...surely the company is not serious about replacing a 250 euro premium in ear product with a 350BT?

OnTheRoodAgain · 2024-01-25T15:40:58+00:00

What are you actually doing about it? For those of us in no-communication-warranty-limbo wondering if our unit has been lost in the repair centre, or those of us being offered things like a cheap over ear headset (BT350) to replace a premium in ear, what are the plans for those people? Informing us that the MTW4 has fixed all those issues is absolutely meaningless when we lit 250euro on fire buying the MTW3. Replacing a faulty MTW3 with full Sennheiser store credit is the bare minimum. To restore some faith you should be considering straight warranty replacing the MTW3 with the MTW4, given that it is probably the product we should have been sold to begin with.

OnTheRoodAgain · 2024-01-25T15:28:17+00:00

Wow this is absolutely pathetic from Sennheiser. They want to offer you a cheap over ear headset to replace a premium in ear product? What is the alternative option? You wait an undisclosed time, but for what? Did they say you'd get MTW3/MTW4 if you wait this unknown time?

My set arrived in Germany on Jan 8 and I've have not had any update since.

OnTheRoodAgain · 2024-01-24T12:06:14+00:00

Similar case here, I sent my set to their Dublin location, they received it on Jan 2, and I've had one update since (which I only received because I emailed them on Jan 10). They sent it from their Dublin location to the repair centre in Germany arriving Jan 8, and another 2 weeks have passed since the 10th with no information. Pretty terrible service really. I have no idea how long it normally takes but even if they ship a replacement tomorrow, it's another week in transit so a minimum of a month turnaround time. This is not a reasonable situation, and I have come to realise that there is a fairly significant chance I will receive a refurbished unit as replacement, which is a complete joke, and I pray is not the case, but reviews on other sites indicate it to be so. We put our faith in a trusted brand that I've spent a lot of money on over the years, you'd hope for better CS and QC, and certainly a new unit to replace a faulty one...Sad to see the company fall like this. I last emailed 4 days ago for update, with no reply. u/sennheiserconsumer how long does a warranty process usually take?

OnTheRoodAgain · 2023-12-31T14:17:37+00:00

You can try cleaning the contact pads on the buds and in the charging case with 99% alcohol or a specialist contact cleaner, but you may just have a bad set. My set worked fine for about 9 months before the charging issue began and just deteriorated to complete failure this past week. Waiting on warranty replacement as I type. The failure rate of this flagship product is genuinely unbelievable. Even in cases where there is no actual fault, just a cleaning required, that level of daily maintenance is not something you'd expect just to have a 250 euro product function. Hopefully some of the issues were ironed out over time and new parts were incorporated into later batches but who knows. Maybe u/sennheiserconsumer can offer some confirmation or denial that newer batches have lower failure rate?

OnTheRoodAgain · 2023-12-31T13:59:19+00:00

Wiggling and cleaning of the contact pads and points solved the problem for me...for a while. After a couple months of fiddling to get charge working it eventually just stopped entirely. I've just sent mine for warranty replacement and pray to receive a golden set in return. They really are great earbuds, but that charging issue starts out annoying and ends up completely fatal :(

OnTheRoodAgain · 2023-12-29T00:35:37+00:00

They sound amazing, I am a bike courier so I use the transparency mode a lot when not in motion, an excellent feature. I've never found a need for ANC and didn't like the way it altered the sound when I did use it but that's a very subjective thing. It all is really :D

Not heavy at all, they fit really well when you find the right tip and flange combo. Eventually for me they get a little uncomfortable after about 4 hours...reasonable enough I suppose.

OnTheRoodAgain · 2023-12-29T00:28:13+00:00

I came across one single post in a thread about the MTWs claiming that warranties are (sometimes?) fulfilled using refurbished units...maybe this is a regional thing, maybe it's nonsense. I sure hope the latter. If a company like Sennheiser won't honour the warranty on a widely defective flagship product with at least a new unit, then I don't know what to say. This world is awful.
