I was told to get a pair of house shoes by my foot doctor. The only time I have had any issues with the heel strap slipping (as some reviewers have noted) is when my heels are really dry, but thats an easy fix. I cant imagine someone 250 pounds using this. スマホに使うハイレゾのイヤホンを探してホームセンターの商品を買ってはみたものの、かつて使っていたモノと同じ。音質はイマイチ。音量を上げないとよく聞こえないし( -｀)が、ウォークマンで以前使っていたハイレゾイヤホンは音量をそんなに上げなくてもよーく聞こえて音質も良かったのを思い出し、それがソニーさんの商品だったので同じメーカーものをアマゾンで検索、で、この商品を見つけたのです！いや～、良きです。色も好きだし、音も良し。 The regular buds are too hard and they dont stay in throughout the night and the plastic makes my ears hot. At first, the door would not shut properly. Her favorite color is blue so she loves them too. LOVE them! but um. A plus point in favor of the Samsung buds is that they get regular updates through the app, some performance related.
