Vifa Copenhagen 2.0: $800 Amazon
Pros: Fabric finish is easy to clean and cozy to touch. Durable - dropped from 2m with only minor scratches. Wi-Fi/AirPlay/wired (optical, aux, USB) in addition to Bluetooth. ~5 hour battery at full volume.
Cons: 350hz and 2-3khz peak. The Vifa Helsinki is cheaper and generally has a more neutral frequency response, I’d highly recommend getting one of those instead if you specifically want a Vifa. Not sure I can recommend this one generally these days, the Uboom L has 95% of the sound quality with more features and a way cheaper price. No water rating.
