Sennheiser MOMENTUM 4 Wireless vs Audio-Technica ATH-M50xBT2 (Black)
The Sennheiser MOMENTUM 4 Wireless is the flagship option here, boasting a remarkable 60-hour battery life, even with Active Noise Cancelling (ANC) on. In contrast, the Audio-Technica ATH-M50xBT2 (Black) offers a solid 50 hours but lacks ANC altogether. In real-world use, the MOMENTUM 4's superb audio quality and long battery life make it a standout choice for audiophiles. However, if you're looking for something more budget-friendly and don't require noise cancellation, the ATH-M50xBT2 still brings the heat with its high-resolution audio capabilities via the LDAC codec.
