Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- InSet 7 Black ZS (Zero Stack) Upper: ZS44 / 28.6 Lower: EC44 / 40 Compatible with 1-1/8" ＞ 1.5" standards Headset Compatible with ZS (Zero Stack) standards Headset InSet is compatible with Zero Stack (ZS) and Zero Stack (ZS) & External Cup (EC) mix specifications.
