纽约的GRADO耳机主力是Prestige系列，从SR60到SR325。这个系列耳机的产品型号已经定型十几年了，只靠后缀区分，从无后缀，到 i 后缀（2009年），到 e 后缀（2014年）。现在宣布了2021年将推出新一代X后缀机型，包括SR60X、SR80X、SR125X、SR225X、SR325X。本来按厂家计划X后缀一代2020年就应该上市的，因为众所周知的原因拖延到了2021年春季。 

具体的新品情况我拷贝厂家的原文如下，自己看。包括新设计的耳机单元（新的磁路结构、新的音圈和振膜）、新的耳机线（60和80为四芯，125、225、325为八芯）、新的头带设计（佩带更舒适）。  

从下面这张官网的图片可以看出SR125X的头带和线材已与之前的完全不同。

New speaker design

The enhanced X Series speaker design encompasses a new magnetic circuit that’s been revised for improved efficiency in conjunction with a newly designed voice coil and diaphragm to further reduce distortion and enhance harmonic integrity. As a result the new Prestige series is easier to drive across a variety of portable devices and deliver the best audio performance possible.

New cable design

The Prestige X Series deploys a new cable design offering more durability and flexibility. The 8-conductor (SR125X, SR225X, SR325X) and 4-conductor (SR60X, SR80X) cables now feature a super annealed copper wire to deliver an improved purity of the audio signal. Being faithful to the recorded event is and always will be a priority for Grado.

Headband redesign

Grado headphones have always been designed for comfort, especially when enjoying long listening sessions. The Prestige X Series redesign to the headband improves comfort which reduces listening fatigue. The headband has a leather aesthetic, however, is a synthetic protein material which means it is vegan-friendly, except for the SR325X which continues to use a leather headband.

从官网公布的SR325X图片来看，SR325X用了新的Flat耳罩，和HEMP耳机相同。不再是之前那种“空心海绵耳罩”。  

SR80X的图片可以看到新的耳机线及头带。耳罩仍为之前那种软海绵罩。

最后，据从厂家得到的消息，X后缀的新款价格会上涨，特别是SR60X会涨幅不小。目前安润还有少量e系列的存货可以考虑。
