I'm not convinced that ANR necessarily offers better hearing protection- after all the headset is pumping even more energy into your eardrums. Contentious point but not unfounded . I've tried all sorts of hearing protection, including ANR in a far noisier environment than an SEP. My current solution works as well as any other - moulded ear plugs with filter and passive headset. Bose (used to?) have very poor passive protection. DCs are very popular in FW world but I would go for a Peltor. Better passive protection, lightweight decent quality. Cheap.
