Item as described and shipped fast. Sounded better than my previous FOSI BT10D. The binding posts are a bit close together due to the small size of the unit so connecting up to speaker may be a bit challenging.Yet to try the subwoofer out, will update when I do.

I was previously using a small & cheaper BT 2.1 channel power amp with the same Texas Instrument's TPA3255 chip. However, Fosi Audio BT30D Pro works much better than the previous one. The difference is obvious. The only part I can point out is that the mid-range is slightly weak. It's a really good class-D power amp for this price range.

Ordering experience was great, Delivery was quick, packaging was also great. Coffee included in it was a Big Surprise. The device is genuine, sound quality so far is unexpectedly good. Never expected such great sound quality from such a portable amp. If I need to buy any thing again in future, the audio store will be my 1st preference.

This little amp really kicks. Sub out is nice. Would be nice if it had more LEDs and remote but still great for the price for what it does. Runs my garage system using old drivers and sub from old Klipsch 2.1, but works perfectly.
