The Sony WF-1000XM4 TWS earbuds are among the best in their segment. However, the models are already two years old, so we can expect their successor, the WF-1000XM5, in the near future.
It is reported that the WF-1000XM5 will offer up to 24 hours of battery life with the case. Fast charging will be supported - 3 minutes in the case will be enough for an hour of work. They also indicate that the case supports wireless charging.
The approximate price and date of the announcement of the Sony WF-1000XM5 are not yet known.
