HiBy W5 Bluetooth Hi-Fi Headphone Amplifier In The House: Unboxing and First Impressions

Man…When I first read the specs on the HiBy W5 Bluetooth Headphone Amplifier, I couldn’t help but back it on Kickstarter. For $69 I got a wireless headphone amp that can drive 300-ohm headphones, supports Hi-Res wireless connections and sports a top-flight ESS Sabre DAC chip. I figured I couldn’t lose. Most of the Headphone geeks I spoke with said it can’t compete with the Earstudio ES100 since it doesn’t have a balanced output, but this thing is cheaper and claims to transmit 192khz sample rates, which the ES100 can’t do. Not to mention it’s tiny!

I’m just starting to play with the W5 Headphone Amp, and so far I can say I like the sound quality. I’ve used it by itself and as a Bluetooth receiver for my Burson Soloist MKII….it sounds divine in both settings. The only gripe I’ve had with it so far is the touch controls…it seems very finicky so far, and I find myself wishing that the damn thing had a physical button or two. I’m going to play with it a little while longer then I’m going to write a proper review…Stay Tuned.
