Bluetooth 4.2 versus Bluetooth 5.1

Bose strives to always deliver a great product with great performance. We take everything into consideration when designing a new product. We look at the benefits to all features and functions. Since there was no change in the specification of the Bluetooth A2DP stereo audio profile, the enhancements between the two versions (Bluetooth 4.2 and Bluetooth 5.1) had no bearing on the audio performance of the soundbar. Given the limited benefits of Bluetooth 5.1, we made the decision to use hardware installed in previous soundbars which have the benefit of thorough field testing along with proven interoperability and reliability.
