Review: a great option for those seeking a compact, affordable, and high-quality amplifier - The Fosi Audio HT4S is a compact yet powerful Bluetooth amplifier. It combines Bluetooth connectivity, solid build quality, and impressive sound performance into a small, user-friendly package. Design and Build Quality The first thing you'll notice about the Fosi Audio HT4S is its sleek and compact design. Housed in a sturdy metal casing, the amplifier feels durable and well-made, with a minimalist aesthetic that can easily blend into any home audio setup. Its small footprint makes it a perfect choice for users with limited space, whether on a desk, bookshelf, or entertainment center. The front panel features simple and intuitive controls, including a volume knob, input selector switch, and an LED indicator. There are also several input options, including RCA and Bluetooth, making it versatile for connecting multiple audio sources. The Bluetooth antenna is discreet yet effective, ensuring a stable connection. Features and Connectivity The Bluetooth 5.0 capability of the HT4S is one of its standout features. It offers seamless wireless connectivity, allowing you to stream music from smartphones, tablets, or laptops with ease. Pairing is quick and reliable, and the Bluetooth range is impressive, maintaining a stable connection even across larger rooms. The Bluetooth signal supports aptX, which ensures high-quality audio streaming with minimal latency. In addition to Bluetooth, the HT4S offers RCA inputs, allowing for wired connections to a wide variety of audio devices, CD players, or desktop computers. This makes it a versatile amplifier, suitable for both modern and traditional audio setups. Sound Performance For such a compact amplifier, the sound quality of the Fosi Audio HT4S is remarkable. Powered by a high-performance amplifier, it delivers clean, powerful sound that punches above its weight in terms of size and price. The HT4S can drive a wide range of speakers, from small bookshelf models to larger floor-standing units, with ease. The sound signature is balanced and detailed, with a slight emphasis on the midrange and highs, making it ideal for vocal-heavy music or instrumental tracks. Bass is tight and controlled, though not overly boomy. If you're looking for more bass impact, pairing the HT4S with a subwoofer would be a good idea, as it lacks a dedicated bass boost feature. One of the most impressive aspects of the HT4S is its low noise floor. Even at higher volumes, it produces minimal distortion, providing clear and crisp audio output. Whether you're using it for casual music listening or as part of a more serious home audio system, the sound quality is more than satisfactory. Ease of Use The HT4S is designed with user convenience in mind. Setting up the amplifier is straightforward, and the controls are intuitive. The volume knob has a smooth, precise feel, and switching between inputs is as simple as flipping a switch. The LED indicator makes it easy to see which input mode you're in. Durability and Heat Management The metal housing not only looks sleek but also helps with heat dissipation. The HT4S runs cool, even during extended listening sessions at higher volumes. This is an important feature, especially for those planning to use the amplifier for long hours. Its solid build also suggests that it will stand the test of time with proper care. Price and Value At its price point, the Fosi Audio HT4S offers excellent value for money. It’s hard to find such a compact amplifier that delivers on sound quality, build, and Bluetooth performance at this price range. It’s an ideal choice for those looking for an affordable yet high-performing amp to power bookshelf speakers or create a wireless streaming setup. Final Verdict The Fosi Audio HT4S Bluetooth Amplifier is a great option for those seeking a compact, affordable, and high-quality amplifier. Its combination of Bluetooth 5.0 connectivity, versatile inputs, and impressive sound quality makes it suitable for a wide range of applications, from casual listening to powering more serious home audio systems. Pros: Compact, durable, and stylish design Bluetooth 5.0 with aptX for high-quality wireless streaming Clean and powerful sound with low distortion Multiple input options (Bluetooth and RCA) Easy to set up and use Cons: Bass output might feel a bit light for bass-heavy genres Lacks a dedicated subwoofer output Overall, the Fosi Audio HT4S offers excellent performance for its price, making it a fantastic choice for audiophiles on a budget or anyone looking to enhance their home audio setup.
Review: Unbeatable for the price - Compact, good sound. Good value for a simple 5 speaker sound setup. No individual volume/balance controls but this wasn't an issue for me.

Compact, good sound. Good value for a simple 5 speaker sound setup. No individual volume/balance controls but this wasn't an issue for me.

### ⭐⭐⭐⭐ Honest review for someone wanting great sound paired with a TV in the bedroom
*by R***. on 28 May 2025*

I bought this to power some old tower speakers connected to my TV in my bedroom. Previously I has a full side, old, marantz avr with an optical in on my bedside table which was huge and great but totally out of place. This came up on offer with a voucher at roughly £105. It reads like a 5 channel amp that might be mistaken for a home theater replacement but it can't decode surround sounds formats so don't buy it thats what you're after. Reviews I found on YouTube were focused on SIM racing using it as a bass rumble module and I'm sure it's great at that. For me I disregarded all that and got it as a small footprint, 2 channel amp that had optical in for the TV. If you forget about the extra speaker outputs and consider it an amp 2 channel amp with a dac I think it's great. It looks lovely. A lot more premium than the similar priced amps that have the inputs on the front and need to be screwed down. It's built well enough to look lovely on a shelf. The remote works great and you can turn off the led indicator for the source input if you don't want to see the light. I've only got it plugged into the optical out of the TV (remember to switch to pcm or you won't hear anything) but it sounds great. I think, if you're not listening to music through a smart TV it would pair really well with a wiim mini for a budget network streaming solution. And it's got a sub out. I think an under the radar great start to a pretty premium, small footprint, separates setup. So far so good. And you can plug an Amazon echo via the 3.5 mm jack or Bluetooth to it so a very versatile device
