I wanted to post the years worth of RMA's from my Fedex shipping account, but they only keep 180 days. I have replaced MTW2 and MTW3 at least 6 to 10 times over the course of years, including with the shipments to extended warranty. And I got paid out on both of them. The quality control on these products is disastrous. I only bought this(with 3rd party warranty), because this has the codecs I want. On reddit the fanboys got furious at me mentioning it, and regurgitated some corporate line about how the problems only existed on the 3 with the battery. All lies.
That being said, I'm using them right now. The fit test is good, did not validate my fit when the tips where inverted in my ear even though I couldn't tell. If you take out the earbuds, it almost instantly connects(iPhone). Bluetooth has come a long way. Listening to AptX adaptive on FMA120.
I'm pretty irritated to see a screen having you select 4 different modes in the Sennheiser app. Standard, low latency, AptX adaptive, and lossless. And you need to put them in the case to restart them to take effect. The phone doesn't support any of this, so why is this shown to me? Is this implying I need to do this arduous nonsense to switch codecs with my dongle? Why?
Already ran into a bug. The multipair only supports 2 devices which is fine/obvious?. But I cannot delete one of my devices from the buds. I wouldn't care if I could add MORE than 2 devices, but windows is not detecting the buds. So I can't deduce anything from this other than it only stores 2 devices at a time which is ridiculous.
I may or may not have heard the MTW2 and MTW3 bug where the left side stays closed when you put on transparency. Given Sennheiser, I would flip a coin to assume it's already on here. I can't get any LE audio out of this which is not surprising because they said I wouldn't.
edit:
I appear to be on LC3. Not sure if accurate. Doesn't sound great but trying to configure this has been dodgy for me. I barely know how to use this atm. I am in "high resolution" mode. So it appears they were just careless in designing the iOS interface.
edit 2:Works in LC3 but does not seem to like the Auracast. The "gaming mode" with 25ms I'm waiting for seems to rely on this. Attached is the email from chipset firm explaining this. Would have liked to test the LE directly with windows but...see the bug above.
