It's important to keep this in mind as you read my thoughts on the WF-1000XM3s, Sony's latest true wireless earbuds. Wires? No wires? Headphone jack? USB-C? Over-ear? In-ear? True wireless? What's your budget? Do you care about sound quality or, given the lowish resolution of streaming media, is comfort more important? Are you outdoors a lot? The headphones should probably stand up to more than a light rain shower. Then there's the purpose of the headphones themselves are they for intense home listening - just you and the music - or for a clamorous daily commute? Do you intend to run with them? If so, they need to stay put during the strain of repetitive motion. Reviewing headphones isn't the same you have to contend with so many variables. People read the review, one of likely many, and come to the conclusion that it's either for them or it isn't. You do some tests - call quality, photos, maybe a drop test if you're feeling bold - and you write about the experience. You unbox it, put your SIM it in, set it up, and start using it like the phone before it. I wouldn't say reviewing phones is easy, but there's a sameness to it.
