The Yamaha 66K-13907-00 and 66K-1397-00 are part of the **Yamaha YAS-660** and **YAS-660B** (or similar) series, which are compact, portable soundbars designed for home entertainment. Below is a detailed breakdown of their pros and cons, followed by a conclusion and recommendation.

---

### **Yamaha YAS-660 (Model 66K-13907-00)**

1. **Compact and Space-Saving Design** The YAS-660 is one of Yamaha s smallest soundbars, making it ideal for small rooms, apartments, or spaces where a larger setup isn t practical. It blends well with modern decor.

2. **Wireless Subwoofer Included** The bundled subwoofer enhances bass response, which is often lacking in small soundbars. This makes it suitable for movies and music where deep bass is desired.

3. **Dolby Digital and DTS Support** It supports Dolby Digital and DTS decoding, allowing it to process high-quality audio from Blu-rays, streaming services, and gaming consoles, though the output is still limited by its size.

4. **Bluetooth and Aux Input** Easy connectivity for streaming music from smartphones, tablets, or other devices via Bluetooth or a 3.5mm auxiliary cable.

5. **Virtual Surround Sound (Yamaha s YSS)** Uses a built-in processor to simulate a more immersive audio experience, which can be effective for movies and games in a small space.

6. **Affordable Price** Compared to larger soundbars with similar features, the YAS-660 offers good value for its price point.

7. **Easy Setup** Minimal wiring and setup; the wireless subwoofer connects via Bluetooth or a cable, and it pairs easily with TVs via HDMI ARC or optical audio.

8. **Decent Speaker Quality for Its Size** The tweeter and midrange drivers produce clear, detailed sound for its compact form factor, though it lacks the depth of larger systems.

1. **Limited Power and Bass** At just 60W (RMS), the soundbar is underpowered for larger rooms or high-volume listening. The wireless subwoofer helps, but it may still feel weak in comparison to larger systems.

2. **No Wireless Rear Speakers** Unlike some competitors (e.g., Sonos, Bose), the YAS-660 lacks a full wireless surround sound setup. The subwoofer is wireless, but the main speakers are not.

3. **Basic Soundstage** Without a dedicated rear speaker or Dolby Atmos support, the "surround" experience is simulated and may not feel as immersive as larger systems with physical rear speakers.

4. **No Built-in HDMI eARC** While it supports HDMI ARC (Audio Return Channel), it does not support eARC (enhanced Audio Return Channel), which limits its compatibility with newer TVs and high-resolution audio formats like Dolby Atmos.

5. **Plastic Construction** The build quality is functional but not premium; some users may prefer a more robust or metal-accented design.

6. **No Voice Control Integration** Unlike some competitors, it does not natively support voice assistants like Alexa or Google Assistant for hands-free control.

7. **Limited Party Mode** The YAS-660 does not have a dedicated "party mode" or multi-room audio capabilities, which are features found in more advanced systems like Sonos.

8. **No Subwoofer Volume Control** The wireless subwoofer s volume cannot be adjusted independently from the main soundbar, which can be limiting for balancing bass in different scenarios.

### **Yamaha YAS-660B (Model 66K-1397-00)**

The **YAS-660B** is essentially the same as the YAS-660 but may include slight variations such as a different color finish (often black or white) or minor firmware updates. The pros and cons remain largely identical to the YAS-660 above, with no significant differences in performance or features.

---

### **Conclusion**

The **Yamaha YAS-660 (66K-13907-00) and YAS-660B (66K-1397-00)** are well-suited for users who prioritize **compactness, simplicity, and affordability** without sacrificing too much in terms of audio quality. They excel in small spaces where a large soundbar would be impractical, and their wireless subwoofer adds meaningful bass enhancement. However, they are not ideal for **large rooms, high-volume listening, or users seeking a fully immersive surround sound experience** without compromise.

If you value **ease of use, basic Dolby processing, and a no-frills setup**, this soundbar is a solid choice. For those who want **more power, wireless rear speakers, or advanced audio features**, you may need to consider larger or more expensive systems (e.g., Yamaha YAS-300, YAS-510, or competitors like Sonos Beam or Bose Smart Soundbar 900).

---

### **Recommendation**

- You have a **small room** (e.g., bedroom, apartment, or office) and need a minimalist audio solution.

- You want **wireless connectivity** (Bluetooth, HDMI ARC) for easy streaming and TV audio.

- You appreciate **basic Dolby processing** and a **wireless subwoofer** for improved bass.

- You are on a **budget** and don t need high-end audio performance.

- You prefer a **simple, plug-and-play** setup with no complex wiring.

- You have a **large room** (e.g., living room, home theater) and need **louder, more powerful sound**.

- You want **true wireless surround sound** (e.g., rear speakers that don t require cables).

- You prioritize **Dolby Atmos or DTS:X** support for immersive audio.

- You need **multi-room audio** or **voice control** integration.

- You want a **premium build quality** or **adjustable subwoofer volume**.

- **For a slightly larger but still compact soundbar:** Yamaha YAS-300 or YAS-510 (better power and wireless rear speakers).

- **For wireless simplicity and multi-room audio:** Sonos Beam (Gen 2) or Sonos Five.

- **For high-end home theater:** Yamaha YHT-4950U (with rear speakers) or Bose Smart Soundbar 900.

- **For budget-friendly wireless subwoofer:** Vizio V-Series or Insignia NS-525.
