The Timberwolf's are a copy of Detector Pro's Gray Ghost series...they just "forgot" to include the quality speakers. The last report I had was Timberwolf was out of business. Regardless, we do not sell products that are copied from another persons product. Would any of you appreciate this being done to you? I wouldn't. However, that issue aside, I've used and sold many cheap, good and better headphones for many years. IMHO, the Detector Pro Black Widow's (Gray Ghost series) are super for the Explorer XS. You have dual volume controls, compatibility switch, limiter switch (must have), extra insulation earmuffs, dual pivot point ear cups, adjustable "stay in place" headband, and a lifetime warranty. I've been very pleased with every model that Detector Pro makes. I highly recommend them. Good hunting, David @ Dixie
