This is because the XM4 headphones still have at least one feature the XM5s don’t. The ability to fold up making them more portable and easier to use for travel. They’re also still some of the best noise cancelling headphones around. And right now you can pick them for just $228 which is about the lowest they’ve been in a while, if not ever. In addition to the XM4 headphones, the Sony XM4 true wireless earbuds are also on sale during Prime Day. These are being discounted down to $198. Although we’d still recommend the headphones since they’ll provide better sound quality, if you need something ultra portable, you can’t get much more portable than a pair of earbuds that fit in your pocket. Is $198 still a little out of your budget? Not to worry. Sony is also discounting WF-C500 true wireless earbuds. Which are now down to $58 for Prime Day instead of the normal $99.99 price. Or you can go with the WHCH710N noise cancelling headphones for $68. You’ll get up to 10 hours of listening time on the earbuds or up to 20 with the charging case. And up to 35 hours of listening time on the headphones. Sony XM4 headphones and earbuds Sony WHCH710N headphones and WF-C500 earbuds
