The engineering quality that goes into the Breslmair titanium rims is beyond reproach. They fit the Breslmair trumpet, cornet and flugelhorn bottom parts and also fit the Breslmair 3-piece trumpet mouthpiece system. This allows you to use the same rim with them all. They will overcome the allergy that some people have with gold plated rims and also feel much less cold to the lips in cold environments. For me the V rim feels narrower on the lips than I was expecting. So have now placed and order for Breslmair parts with a wider rim. Due to the price you need to be careful and make sure you order the correct size. The rims are also also available in silver plate at a cheaper price, so it may be a good idea to try these before purchasing the titanium rims.
In summary, these are great quality rims that, with the correct size will enable you to play more comfortably.
