No shops show this model anymore but I had a Studio speaker previously so had a good idea on the quality this would offer.We compared Sonos, Marshall, JBL and Bose. None of these compared to the deep bass, room filling sound and overall great looks. £180 is an absolute bargain for this power house.Reviews I've read mentioned poor battery life (less than 6 hours) but as I am more interested in quality of sound rather than the longevity of the battery it was a no brainer.You will not be disappointed with this speaker ## Frequently Bought Together - Harman Kardon Onyx Studio 7 - Portable Bluetooth Speaker Black - DJI Osmo Mobile 6, 3-Axis Phone Gimbal, Object Tracking, Built-In Extension Rod, Portable and Foldable, Android and iPhone Gimbal, Vlogging Stabilizer, YouTube TikTok Video, Slate Gray --- ## 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.pl/products/373238662-harman-kardon-onyx-studio-7-portable-bluetooth-speaker-black](https://www.desertcart.pl/products/373238662-harman-kardon-onyx-studio-7-portable-bluetooth-speaker-black) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-09-16*
