The Sony WF-1000XM4 may be priced at the higher end of the wireless earbud market, but they really do offer a premium experience with amazingly good sound and a myriad of features.

- Excellent noise cancelling
- Very good transparency mode
- Foam earplugs insulate very well
- good battery life
- Support for SBC, AAC & LDAC
- Powerful sound
- smart ANC
- very long running time.
- Only three attachment sizes
- moderate on the phone.
The WF-1000XM4 sound powerful and natural and have one of the best noise cancelling systems with good adjustment options on board. However, the Sony in-ears are no experts for phone calls: speech sounds a bit muffled, background noise is audible.
The noise-cancelling feature of the Sony headphones works very effectively and adapts to different situations. The sound is undistorted and balanced.
New in Stiftung Warentest's headphone comparison: 32 current in-ear and headband headphones. One of them delivers top sound, another is top fit for sports. In addition to the test winners, the current test offers many other good headphones. With long battery runtimes of up to almost 86 hours, the headphones with earpieces scored particularly well...
For the higher price, there is a convincing sound image by in-ear standards, good ANC and an exemplary sound app.
