The sound quality initially did not seem very great indoors during the first tests. I later used the speaker for an outdoor BBQ event with roughly 80-120 people in a large field beside a pond. It was able to produce adequate volume to cover a very large area without sounding harsh or distorted. The battery lasted for the full event and really surprised a lot of the guests. For the sale price I paid for this speaker, it is a tremendously good value. With use the sound quality has improved a lot, the drivers must have needed to be worked in properly. If you position it correctly for the room, it can produce some seriously impressive bass frequencies for a bluetooth speaker. Can't speak for long term reliability, weather resistance, or compare it to other speakers, but can honestly say if this comes on sale again, you can't do wrong picking one up. Realistically speaking the regular retail price is not all that bad considering the performance. ## Frequently Bought Together - W-KING 300W PEAK Party Large Speaker, 40Hz Massive Bass/Subwoofer 7.5“, Big Portable Speaker with IPX7 Waterproof/Sound APP/EQ/Fast Charging/Stereo Pair/OTG/TF/USB/AUX,Loudest Wireless Outdoor Boombox - W-KING Portable Speakers Bluetooth Wireless, 120W Max Loudest Bluetooth Speaker, IPX6 Waterproof Outdoor Speaker with 70W Deep Bass/2*Subwoofer/DSP/EQ/42H/LED/MAC-in/Power Bank, Large Party Boombox - W-KING 90W Peak 50W RMS Powerful Bluetooth Speaker - IPX6 Waterproof, Large Outdoor Portable Wireless Deep Bass, 40H Playtime, Power Bank, TF-Card, AUX, NFC, EQ --- ## 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.jp/products/613431004-w-king-loudest-boom-box-7-5-subwoofer-2-1ch](https://www.desertcart.jp/products/613431004-w-king-loudest-boom-box-7-5-subwoofer-2-1ch) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-16*
