Its Crazy! how much of the same is there on the internet, complaining for the same things... I am one of them who has faced same issues for TW3s and TW4s... I will never buy them again....I bought TW3s on May 2022first fail with squeaking sound and returned on June 2023 // replaced with new TW3ssecond fail with completely dead buds and returned June 2024 // replaced with new TW3sHere there and in between I had oftentimes to reset to factory settings as it would start disconnecting, interrupting music, mic not working etc...gave up & gave away TW3s...SENNHEISER PROMISSED THAT THEY FIXED TW3s issues in new gen - TW4sHave been naive and I bought TW4s on February 2024first fail with dead right bud and returned on September 2024 // replaced with new TW4ssecond fail with dead right bud and returned on September 2025 // yet to ship, expect for the new onesAgain, every 2-4 weeks I had to reset the buds as it would not connect to the phone/laptop, it would suddenly disconnect or have distorted sound.It is frustrating that the item, priced at such premium level of £250-£300 performs so poorly... Ohh and it takes like a month to get replacements!The 2 year promised guarantee is ridiculous, what do you do when warranty expires and it fails there on the spot...You can see that I got "lucky" that the buds failed second time just at the end of guarantee period.... Else I would be out the cash, the buds and with massive disappointment.they should be honoring replacements way beyond that and do minimum of 5 years with promise to replace with new generation, hoping that they have fixed all short comings from previous gen...Thanks Sennheiser, I will have to fly tomorrow without the earbuds...NEVER AGAIN,
