Few companies compete with Sonos when it comes to portable speakers, but at $159 for the cheapest offering (the new Sonos Roam SL), owning a Sonos Bluetooth speaker doesn’t exactly come cheap. Fortunately, there are a number of companies making decent Sonos alternatives these days, at a fraction of the price.

Case in point: this Harmony Capsule 300 Portable Bluetooth Speaker from Monoprice. Amazon currently has this best-selling Bluetooth speaker on sale for just $64. Regularly $82+ a surprise sale gets you a 22% discount off the already-low price.

Buy Harmony Capsule 300 Speaker $64.60

The Harmony Capsule 300 was just released this past spring, and this is the first time we’re seeing this model discounted online.

This Amazon deal gets you the Monoprice portable speaker for under $70. With its sleek black colorway and cylindrical shape, the Harmony Capsule is a Sonos dupe for one-third the price. Great for both indoor and outdoor use, the portable speaker delivers 30 watts of big, booming sound from a pair of 52mm drivers and one 66mm speaker driver.

Bluetooth 5.0 ensures easy pairing to your phone or computer (from up to 32 feet away), while a built-in microphone lets you answer calls from the speaker (I.e. no need to search for your phone). The microphone is compatible with smart assistants like Siri too, so you can control settings using just your voice.

The Lithium‑ion rechargeable battery gets you up to 30 hours of playback time before needing to be plugged in. The speaker is also rated IPX7 on the waterproof scale, meaning it can withstand splashes of water or rain without worry (it can also be immersed in water up to three feet deep for an hour without damage).

For comparison, the Sonos Roam gets up to 10 hours of playtime and is rated IPX67 — meaning you should avoid submerging it in water for more than 30 minutes. The Sonos is also a little smaller, coming in at just over six inches (or about the size of a Starbucks Venti cup), while the Harmony Capsule is slightly larger at around eight inches in length.


Still, both devices are still super portable and lightweight, tucking easily into a bag for an outing to the beach or park, or sitting in a corner of your room for loud, wide-ranging sound.

Normally $80+, the Monoprice Harmony Capsule Speaker is a great Sonos alternative and on sale for just $64. This deal includes the portable speaker, charging cable and a carrying strap for portability. See full details on
