his earbuds: 1More Triple Driver in-ear headphones

meanwhile, Yamaguchi is a loyal Sony fan. Starting out he had one of those weird Sony all-in-one headphones: Sony Waterproof Walkman® with NFC™ & BLUETOOTH®...

and then under Kageyama's influence, he got the Extra Bass wireless headphones: Kageyama thinks too much bass is a travesty though

Tanaka favours earbuds. He has a few, but the Shure SE215 is his favourite

Shure SE215 Wireless

Hinata has low-end earbuds for music on the move, otherwise he much MUCH prefers playing it openly Sony EX110AP In-ear Headphones

Yachi doesn't put a lot of stock into what kind of earphone/headphone she has, but recently Shimizu gave her the Sony h.ear mini wireless and she's been using that ever since
