在考虑给我的周末骑行装备升级。现在买一个中端头盔，还是再攒一阵子上高端款，拿不定主意。那些升级过的人——你们真的感觉到舒适度或噪音方面有提升吗，还是说主要只是品牌溢价？

Thinking about upgrading my setup for weekend rides. Torn between buying a mid-range helmet now or saving a bit longer for a premium one. Anyone who made the jump—did you actually notice comfort or noise improvements, or is it mostly branding?
