I had a chance to test and compare two models: Samsung S50B vs Sonos Arc and this review should help people who are looking for a good soundbar. The Samsung S50B was rated 4.6, while the Sonos Arc has a rating 7.
Each of the models under consideration has active amplification type. The built-in subwoofer is not implemented in any of these models. An external subwoofer can be connected to any of the units in this comparison. Rate 6 out of 10 received the Samsung S50B for audio features and specs, but the Sonos Arc received 5 out of 10. The Arc can play audio from Spotify.
Wireless Internet connection is realized only in the Arc. Soundbars from this comparison have Bluetooth support. There are 0/1 HDMI inputs/outputs in the Samsung S50B versus 1/0 HDMIs in the Sonos Arc. As in the S50B, so in the Arc there is the HDMI Audio Return Channel (ARC). The connectivity of each of the models was estimated at 7/10. The manufacturer of the Arc provides a device control application. The Sonos Arc equipped with a microphone. The models under consideration cannot become part of a multiroom system.
Dolby Atmos audio decoder is onboard the Arc. Devices from this comparison cannot process surround sound due to lack of DTS:X. The S50B was rated 6/10, while the Arc received a mark of 4/10 for multichannel surround.
