Just make sure you install it in the right orientation the first time. The sound quality is very, very good, and stays good at high volume. Not quite good enough for an absolute purist audiophile, but way better than the typical listener might expect or need in order to be satisfied. The ULT button is useful, but I recommend using the graphic equalizer on your phone to fine tune it, if you can. Battery life is great as long as you aren't pushing the volume to max or almost max all day. The lights are a bit bright but you can turn them off, or dim them in the app, and even change the pattern they move in. There are several useful features in the app, but I recommend printing the user manual from Sony's website. Also recommend getting a silicone cover and a zippered carrying case. Overall I feel this is the most practical and useful portable speaker I've ever had. ### ⭐⭐⭐⭐⭐ Top-tier sound and endless battery. Worth every penny! *by on Reviewed in the United States August 5, 2026* This Sony speaker has turned out to be an excellent purchase. The sound is top-tier, with great power, and the Bluetooth connection works flawlessly. Although it is a bit heavy, I take it with me every day because it is incredibly useful. What stands out the most is the battery life: it lasts through my entire night shift until 7:00 AM and still has charge left over. I am completely satisfied with the quality and performance of this device; it is truly worth every penny I paid for it ### ⭐⭐⭐⭐⭐ Great powerful speaker *by on Reviewed in the United States March 29, 2026* I was pleasantly surprised by this speaker. The sound quality is real good for a portable speaker. I’m going to consider it portable because it has a well thought out strap and you can take it places with you. It is kind of heavy and large, but the dimensions are in the product description so nothing that I didn’t already know. The build quality of this speaker is top notch. When you hold it in your hand you feel like you got something for your money. The materials look and feel good, and the bass speakers in the end are well protected and punchy. I use this on a sailboat, pontoon boat, camping trips, and in the backyard. It just works and sounds great everywhere. I have gotten it wet and used it in very dusty environments with no issues. As far as sound goes, I’m not sure you could beat it with a speaker the same size or price. It is crisp and bass sounds good. At 100% volume it gets a little out of control but that is almost every speaker on the market. The battery life is all day with no issues. It has never died and I have used it for 10+ hours straight. ## Frequently Bought Together - Sony ULT Field 5 Wireless Portable Bluetooth Speaker, IP67 Waterproof, Dustproof, and Rustproof with Enhanced Bass, 25 Hour Battery, 360° Party Light, and Shoulder Strap (SRSULT50B), Black - Sony ULT Field 1 Waterproof Portable Bluetooth Speaker, Enhanced Bass, 12h Battery, IP67 Rated Dustproof Shockproof Rustproof, Detachable Strap (SRSULT10B), Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/717467767-ult-field-5-wireless-bluetooth-portable-waterproof-speaker-black-25](https://www.desertcart.fr/products/717467767-ult-field-5-wireless-bluetooth-portable-waterproof-speaker-black-25) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-08-15*
