Review: Great speaker with useful features and a good design - A good speaker with a mode that boosts the bass. The battery is good can go days without needing to be charged. It is compact for easy traveling with it. It is light weight and comes with an attachable shoulder strap for carrying it hands free. For the price it's a great speaker with a lot of useful features and a built in mic for calls or voice assistant. Review: One is perfect two can be tricky connecting. - The sound on the speaker is absolutely amazing. The app for the speaker however needs a lot of work. The sound was so good I immediately bought a second one the day I got the first one so that I could utilize the "party connect" feature which allows you to connect up to 100 of these. The instructions on how to do it are as clear as mud. I've been able to get the speakers to connect two times, every time you turn on the speaker if you're going to connect a second speaker you have to go through the process each time. It took me about 25 minutes the first time in about 18 minutes the second time. The key is to only connect one speaker to your phone or tablet via Bluetooth, then hit the connect button on the first speaker, then turn on the second speaker without connecting it to Bluetooth hit the connect button on the second speaker. I had to go through the process several times including deleting the app removing the connection from my iPad and starting over. If you're only going to get one of these speakers I can tell you it's absolutely worth it the sound is amazing especially for its size. I bought this for when I travel with my iPad to have better sound quality playing movies and it does not disappoint. It gets about 12 hours of battery time if you're using the sound enhancing ULT, otherwise you can get up to 25 hours which is not even advertised for the device if you turn off ULT, I will say though the sound quality drops dramatically by turning off ULT. The build quality seems really nice, it feels like a solid piece of equipment that won't fall apart in your hands. The only complaint I have is the connection of multiple speakers. ## Features - ULT BUTTON: Boost the bass with the press of the ULT button, delivering enhanced sound depth for your favorite tracks. - SHOULDER STRAP: Designed for easy portability, the included stowable shoulder strap makes carrying your speaker effortless. - PARTY CONNECT: Link multiple compatible speakers together for synchronized sound and an epic party atmosphere. - WATERPROOF, DUSTPROOF, and SHOCKPROFF: With IP67 ratings, this speaker is designed to handle the toughest conditions, from beaches to hikes. - UP TO 24 HOUR BATTERY LIFE & QUICK CHARGING: Long-lasting power to keep the music going, no matter where you are.

I use my ULT 3 so much that when I needed something punchier for work I opted for the ULT FIELD 5 & it did not disappoint. The coolest part is they can pair up together, I may invest in an even larger SONY speaker again next. ## Frequently Bought Together - Sony ULT Field 3 Wireless Portable Bluetooth Speaker, IP67 Waterproof, Dustproof, Rustproof, and Shockproof with Enhanced Bass, 24 Hour Battery and Shoulder Strap (SRSULT30H), Forest Gray - Sony ULT Field 1 Waterproof Portable Bluetooth Speaker, Enhanced Bass, 12h Battery, IP67 Rated Dustproof Shockproof Rustproof, Detachable Strap (SRSULT10B), Black - Sony ULT Field 7 Wireless Bluetooth Party Speaker, IP67 Waterproof, Powerful Bass, 30h Battery, Karaoke, Comfortable Handle, and Colorful Lights (SRSULT70), 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.co.uk/products/717710577-ult-field-3-wireless-bluetooth-portable-waterproof-speaker-forest-gray](https://www.desertcart.co.uk/products/717710577-ult-field-3-wireless-bluetooth-portable-waterproof-speaker-forest-gray) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-09-21*
