Those who listen music indoors in medium volume this is a perfect choice. It outperform its size. Sound quality and bass is par with my 50k LG soundbar. But keep in mind that certain places it out perform. If you keep in the centre of room it may not, but if you keep it closer to a wall and corner and you sit closer to the opposite wall then you can witness the real charm of this speaker. Amazon delivery was not good.. they delayed and not ready to do open box delivery. Post escalating to customer support they assigned other delivery person and performed open box delivery. Amazon already charge for open box delivery and some delivery boys won't do seeing the size of the box. We didn't accept the product and escalated issue. Then open box delivery they performed next day. ## 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 (SRSULT30B), Black - Supmay Hard Carrying Case for Sony ULT Field 3 Wireless Portable Bluetooth Speaker, Wireless Portable Speaker Protection Case with Mesh Pocket for Shoulder Strap, Charging Cables, 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.gr/products/735836751-sony-ult-field-3-bluetooth-speaker-48w-massive-bass-24hr](https://www.desertcart.gr/products/735836751-sony-ult-field-3-bluetooth-speaker-48w-massive-bass-24hr) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-09*
