While generally well-received for their sound quality, there's often a gotcha or two that keep them from being top picks. These are areas where similarly priced competitors are notably further ahead, like active noise cancellation or where Yamaha's design gets in the way (like long-term comfort). For a good example of what I'm talking about, check out WIRED's review of Yamaha's premium YH-E700B wireless headphones, which earned only 6/10.
Right now, they're $38 rather than the normal $69, which is a respectable 46% discount. This is one of Amazon's Labor Day deals and it's an easy win if you're looking for a good pair of wireless headphones without shelling out top dollar. Yes, these are not the costly Sony WH-1000XM6 (that cost you ten times this amount) but for everyday listening, they have a lot of quality to make a jump at this price cut worthwhile.
