Sony ULT WEAR WHULT900N/B
85 out of 100 medium confidence 15 reviews
The Sony ULT WEAR headphones deliver impressive noise cancellation and powerful bass via the ULT button, with many users praising the long battery life and comfortable fit. Sound quality improves significantly after using the companion app to customize the EQ, though some find the default sound muddy and the ULT bass boost overwhelming. A few long-term users report scratchy audio after two years, and the headphones are noted as bulky for some.
