Second time ordering from Back Market and I once again was very impressed with the speed of processing and shipment, and the quality of the used/refurbished item. The XM4’s are arguably the best version of these Sony earbuds delivering good ANC, balanced sound, and full, punchy bass. Earbuds case looks practically new and showed no signs of wear; earbuds came memory foam tips that were too small, but that’s an easy fix. Battery life on the earbuds is basically like new, and I enjoy hours of listening on a full charge. Love these things!

Didn’t realize I needed to charge them initially, they didn’t connect, but once I charged them, they connected right away, they are amazing. Perfect condition.

Initially, the device was set to Chinese, but i was able to change the language through the Sony app. Everything so far is fully functional and the earbuds sound great!

Cons - Right earbuds battery drains very quickly, and could only charge to about 80% no matter how long it was left to charge. Every 5-8 minutes, it lost 10% of its charge. I also received silicon earbud tips, rather than the foam that should come with these. The ANC was lackluster to what I expected, likely due to the silicon tips. (I assume this is due to the tips needing to be replaced, and the foam is more expensive than the silicon tips) Pros - Charges very quickly, Sound is good, and the app allows good EQ customization, to tune it to your sound preferences, along with a large selection of premade EQ presets. Very good controls, intuitive, and customizable, though due to the size, it can be a tad awkward to tap it. Personal preference here, while I liked the buds, they are quite large for earbuds, felt a little weird in public truthfully, but they are comfortable, but with how big they are, the tap inputs are positioned higher than most earbuds, so it's something to get use to. At this time, a return has been started, as the battery issue can't be overlooked, however BackMarkets support was amazing, very fast to respond, eager to resolve the issue, even though this is the first time I have purchased from them, and it didn't work out, I will buy from them again at some point due to the outstanding support.

Awesome earbuds. Noise cancelation blocks out all the weird gym music and sounds. Separation of sounds allows full enjoyment of listening

Pretty good. The only minor issue is every once in a while the bluetooth connection will drop, but it happens pretty rarely.
