Build Quality and Design
When investing in a speaker around the 10,000-rupee mark, superior build quality is a top expectation. The Sony ULT Field 1 meets and exceeds this expectation with its robust and premium design. The speaker features a high-quality plastic frame on both the top and bottom, coupled with rubber grips that enhance stability and durability. These design elements not only contribute to its sturdy feel but also enable the speaker to stand vertically like a tower, ensuring versatile placement options without compromising sound quality.

The front of the speaker is covered with a fine fabric mesh, adding a touch of elegance and providing a premium tactile feel. The overall aesthetic is modern and sleek, making it a suitable addition to various environments, from living rooms to outdoor settings.
Controls and Connectivity
Convenience and ease of use are at the forefront of the Sony ULT Field 1’s design. The top of the speaker is equipped with intuitive controls, including:
- A charging indicator
- An On/Off button
- A Bluetooth pairing button
- Play/Pause and Call pickup button
- Volume up and down buttons
- A unique “ULT” button
The back of the speaker houses a Type-C charging socket, which is a modern and efficient choice for quick recharging. The IP67 rating further enhances the speaker’s appeal, ensuring it is both dustproof and waterproof. This makes the Sony ULT Field 1 ideal for outdoor activities, such as pool parties or beach outings, where exposure to water is a concern.
In addition to its rugged build, the speaker includes a convenient strap or lanyard, allowing for easy carrying. This feature is particularly useful for those on the go, as the speaker can be effortlessly attached to bags or luggage, enhancing its portability.
Sound Quality of Sony ULT Field 1
The Sony ULT Field 1 supports Bluetooth 5.3 and AAC codec, ensuring a stable connection and high-quality audio streaming. Its sound performance is where the speaker truly shines. The speaker can produce impressively loud sound without any distortion, even at maximum volume. The clarity of the mids and highs ensures an enjoyable listening experience across various music genres.

One of the standout features of this speaker is the “ULT” button. When engaged, the ULT button significantly enhances the bass, transforming it from punchy to deep and resonant. This deep bass is well-tuned and does not feel artificially boosted, providing a clean and immersive audio experience. The speaker’s tall design allows ample space for the woofer to operate, contributing to the rich, deep bass that enhances music playback.
Battery Life of Sony ULT Field 1
The battery life of the Sony ULT Field 1 is another impressive feature. Under typical usage conditions, the speaker can provide between 8 to 10 hours of playback time on a single charge. This long battery life ensures that users can enjoy their music for extended periods without the need for frequent recharging, making it a reliable companion for both short outings and long trips.
Additional Features and Areas for Improvement
The Sony ULT Field 1 comes with a few additional features that add to its versatility. It includes three preset equalizer settings: Off, Custom, and ULT. The ULT setting, in particular, enhances the bass significantly, providing a deeper and more powerful sound. However, an area for potential improvement is the addition of more preset equalizer options. More presets would allow users to fine-tune the sound to their liking more precisely, catering to different listening preferences.
Our Thoughts
The Sony ULT Field 1 is a stellar portable speaker that offers excellent value for its price of 10,990 rupees. It boasts superior build quality, exceptional sound output with deep, well-tuned bass, and a robust battery life. The IP67 rating and portable design make it an ideal choice for both indoor and outdoor use. While the addition of more preset equalizer options could enhance the user experience, the overall performance of the speaker is highly satisfactory. Whether for casual listening, outdoor gatherings, or travel, the Sony ULT Field 1 is a reliable and high-performing audio companion that will not disappoint.
