Short answer: the Soundcore Boom 2 for value. With Oluv’s or Alan Ross’s EQ applied it delivers solid bass and party-friendly lights for $99.99, against $249.99 for the Stockwell III, and its rating already reflects that value. The Stockwell III answers with a 40+ hour battery that doubles as a power bank and IP55 dust protection, so pay more only if runtime and dust resistance matter most.
The price gap here is stark: a $249.99 premium portable against a $99.99 budget speaker. The Stockwell III offers a parametric EQ app, wall/corner compensation, and a 40+ hour power-bank-capable battery. The Soundcore Boom 2 offers app EQ, IPX7 protection, light-up passive radiators, and party-mode pairing for a fraction of the price.
Choose the Boom 2 for value: With Oluv’s or Alan Ross’s EQ applied, it delivers solid bass and party-friendly lights at less than half the Stockwell III’s price, and its rating already reflects that value.
Choose the Stockwell III for a longer battery and IP55 protection: Its 40+ hour runtime, USB-C power-bank output, and dust protection go beyond what the Boom 2 offers, if those specific features matter more than price to you.
Buy the Soundcore Boom 2. It is rated higher for sound quality than the Marshall Stockwell III and costs less, which makes it the one to get unless you need something the other one does better.
