The top one is top mount. They just work. I purchase these strictly to work out in and use as an everyday shoe and I am extremely satisfied. If they were longer I would of kept them. A lot of time-saving advice and strategies that average-joes and athletes alike can benefit from. Im not an expert when it comes to cartridges but this one does sound really good with my turntable, easy install and safe packaging not hard to replace so go ahead I recommend. Wanted to try these. Noise cancelling on the mic is better on the voyager. Works great for Netflix, Apple Music, Pandora, etc.
