I am doubly happy because I received it emory-Class / dp / B00AYC6V2U / ref = sr_1_2? Ie = UTF8 & qid = 1393670959 & sr = 8-2 & keywords = + microphone + SDHC card instead. It is faster but more expensive. I had not taken because the extra speed would not have served much given me the speed of the videos I put on my J3 is far exceed the maximum throughput of both cards (especially the second course ). But then, having received for the same price, and my Walkman supporting it anyway, I made no fuss!
