### ⭐⭐⭐⭐⭐ Great
*by J***B on 1 May 2026*

Works great and sounds good , very good for price

### ⭐⭐⭐⭐⭐ Amazing product
*by E***D on 12 April 2026*

### ⭐⭐⭐⭐ Simple, Good-Sounding Phono Preamp with Easy Bluetooth Setup
*by M***E on 23 February 2026*

The Fosi Audio BOX X1 with an MM turntable, feeding a Bluetooth transmitter which then connects to my Roth VA4 active speakers. Setup was very easy and worked first time. The turntable goes into the BOX X1, then out to a UGREEN Bluetooth transmitter (set to transmit mode), which pairs wirelessly with the speakers. No apps, no screens, no messing around, just buttons and LEDs. Once paired, it reconnects automatically. Sound quality is better than I expected for the price. The BOX X1 is quiet, with no noticeable hum or noise in my system, and it does a perfectly good job of phono amplification. Over Bluetooth, the sound remains clear and balanced. Yes, Bluetooth is technically lossy, but in real listening terms the loss is mostly academic. I wouldn’t notice it unless I was directly A/B testing against a wired connection. There is a small amount of Bluetooth delay, but in a vinyl-only setup this doesn’t matter at all. It has no impact on listening enjoyment. Overall, this is a very good value phono preamp. Paired with a modern Bluetooth transmitter, it’s a practical and affordable way to get vinyl playing wirelessly without sacrificing sound quality in any meaningful way. Pros • Easy to set up • Clean, quiet sound • Great value for money • Works well with Bluetooth transmitters Cons • MM cartridges only • Bluetooth is technically lossy (but not an issue in practice) I’d happily recommend this to anyone looking for a simple, budget-friendly phono preamp.
