This product gets a 5 star rating form the one and only V.i. P. I have opened up shows performing as a hip hop artist and DJ for rap a lot records, Kurk Kobangz, Lil Wayne and many more. The fact is without these needles the sound wouldn't have had the bass that it did. I would say these are hip hops premier needle for the M44G which is a basic upgrade for the M447. My first pair was stolen during a violent robbery in 2012 but I got another pair and I am rebuilding my empire to twice the strength as before. These needles are the soldiers who will fight with me to the top. It's not common for a good long lasting great sounding product to come around but when it does you need to buy it and keep it. If I ever recover my stolen items I will never lose them again. Thanks amazon for asking my opinion once again and thanks Shure for sponsoring me and sending these to me. You guys are the $&@t!!!
