I am a Sennheiser Fans. Overall the MTW3 is the tip-top level in the industry. While noise cancellation operating, the background is quiet like in deep sea. It is however the serious intermittent disconnection is a critical issue particularly in busy location. The appointment has been made for repair and servicing. But the repair centre is quite remote and long time waiting. It consumes a lot of time on two ways travelling.
Amazing, neutral sounding TW earphones well worth the price. Low end is superbly controlled. Highs could be better but still overall they are very well worth the money. I haven’t used these for exercise though
Sound quality and ANC is great. Compared to B&O Beoplay EX, it lacks clarity, but not far off. For ANC compared to Sony, Sony wf-1000m4 is still slightly better. But overall it's great when commuting in subway, because it hits the balance of sound quality and ANC. In subway, you will appreciate TW3 sound quality more than Beoplay EX because of the ANC. The case is too big and sometime have connections issue in the downside. In conclusion, TW has great sound quality, ANC and priced reasonably.
