Tripowin Amber 32AWG OFC Oxygen Free Cable HiFi IEM Cable with Interchangeable 2.5mm 3.5mm 4.4mm Plug PVC Sleeve for Audiophile

Extremely comfortable, but DOES NOT fit Sennheiser IE series properly

I bought this cable as an ergonomic upgrade for my Sennheiser IE 200 IEMs. In terms of build quality and comfort, this cable is absolutely fantastic. It is incredibly soft, beautifully braided, has zero memory effect, and completely eliminates cable microphonics (rubbing noise against clothes). It feels amazing around the ears and lays perfectly flat on the desk. However, there is one major flaw for Sennheiser users: The MMCX connectors do not snap into the IE 200 housings properly. Sennheiser uses a slightly recessed MMCX socket with a proprietary collar. The plugs on this Tripowin cable are just a fraction too wide/short to slide all the way in. There is no tactile or audible "click" like with the original cable. As a result, the connection is extremely loose. The cable detaches far too easily with minimal tension or slight head movements. While the audio signal itself works, the mechanical fit is simply unsafe for the Sennheiser IE series. Pros: Incredibly soft and flexible material Zero microphonics / cable noise Great premium look and feel Cons: Not fully compatible with Sennheiser IE 200/300/600 recessed MMCX sockets (loose fit, no click) Verdict: If you have standard MMCX earphones, this is an easy 5-star recommendation. If you are buying this specifically for Sennheiser IE series IEMs, be aware that the plugs will sit very loosely and might disconnect on their own.
