The Harman/Kardon Go + Play 3 is a portable home speaker that shares its stylish, understated design with other home speakers from the brand. Its built-in carrying handle means it can accompany you from room to room, and Harman/Kardon promises that its three-way speaker design offers both stereo playback and powerful bass reproduction in a relatively compact package.
Our Verdict
The Harman/Kardon Go Play 3 is decent for listening to music. Though it lacks low bass, which is to be expected given its size, it still packs enough of a punch to keep kick drums feeling exciting, and basslines have a little extra warmth, which fills out the sound nicely. The mid-range is quite balanced, so instruments and vocals alike are reproduced accurately and with detail. A slight boost in the treble range adds a little extra shimmer and presence to sounds like cymbals, without rendering them piercing. The speaker will play back stereo audio and gets plenty loud for medium-sized indoor rooms, though you'll lose some treble range frequencies if you're positioned behind it, as its forward-facing design slightly limits its directivity.
Balanced sound with a good amount of punch.
Handle makes carrying easy.
Plays back stereo audio.
No companion app to customize the sound.
Forward-facing speaker, so treble reproduction depends on your listening angle.
The Harman/Kardon Go Play 3 is okay for watching videos. While it's not quite large enough to reproduce the low-bass rumbles of explosion effects, it does play back stereo audio, so details, like delay tails in sci-fi soundtracks, are present and detailed. It gets loud enough to fill a living room with audio, and its balanced mid-range ensures dialogue sounds natural, too. Its latency with iOS is good, but very high with Android, which can lead to lip-sync issues. That said, different apps and devices compensate for latency in different ways.

The Harman/Kardon Go Play 3 is very good for listening to podcasts. It has a balanced mid-range that reproduces voices accurately and with detail, while it gets plenty loud enough to fill up a medium-sized room with sound. Its carrying handle makes it easy to take with you from room to room, and you can pair it with two devices for easy switching between your phone and laptop. If there's a downside, it's that this is a front-facing speaker, so if you're standing behind it, voices can sound a bit muffled.

The Harman/Kardon Go Play 3 does not support voice assistants.
The Harman/Kardon Go Play 3 is not designed for outdoor use. It's not rated against water or dust ingress, nor does it have an impact protection rating. If you do choose to risk using it outside, you'll benefit from its well-balanced sound and ability to get loud enough to accompany your next summer BBQ. There is a touch of compression at high volumes, though, so it's not an ideal party starter, and its seven-hour battery life is only okay. In short, this speaker is a decent choice for using outdoors, but if that'll be your speaker's primary use, you should look elsewhere.

Popular Speaker Comparisons
The Harman/Kardon Go Play 3 is a portable home speaker that's designed to be carried with you around the house. It's larger and heavier than the Harman/Kardon Onyx Studio 8, which is, in turn, larger and heavier than the Harman/Kardon Onyx Studio 6. The Harman/Kardon Aura Studio 3 is the only 360-degree speaker from the brand we've tested, so it's the one to look into if you prioritize directivity performance.
All the Harman/Kardon speakers we've tested are meant for use indoors. If you're looking for a speaker that will work well both indoors and outdoors, the Bose SoundLink Max and the Ultimate Ears EPICBOOM are both rated IP67 against dust and water ingress, so they're worth considering.
Check out our recommendations for the best portable Bluetooth speakers, the best home speakers, and the best Bluetooth speakers.
The Harman/Kardon Go + Play 3 is about double the size of the Harman/Kardon Onyx Studio 9, so it's probably unsurprising that it gets a lot louder and has a more consistent bass response. Both of these speakers have sleek yet understated designs that should suit most rooms in your home; their lack of IP ratings means you won't want to take them outside, anyway. They also both have loosely balanced frequency responses that suit a wide variety of audio, from podcasts to music. But if you like to tweak your speaker's sound, you'll want the Studio 9 as it comes with a companion app with a 7-band graphic EQ.
The Harman/Kardon Go + Play 3 and the Bose SoundLink Max are portable Bluetooth speakers with different strengths. The Harman/Kardon has better directivity and a more bass-heavy sound, but unlike the Bose, it doesn't come with a companion app to tweak the sound to your preferences. The Bose is better built and rated IP67, so it'll withstand a rain shower or windy day in your garden. The Bose's 15-hour battery life is also much longer than the Harman/Kardon's seven hours.
The JBL Boombox 3 and the Harman/Kardon Go + Play 3 are medium-sized portable Bluetooth speakers with different strengths. The Harman/Kardon has slightly better directivity, making it a better choice for park hangs, where people might be sitting at varied angles around the speaker. On the other hand, the JBL's almost 30-hour battery life is much longer than the Harman/Kardon's seven hours. The JBL is also rated IP67, so it'll withstand getting wet at your garden party, and it has a companion app, unlike the indoor-oriented Harman/Kardon. If you know you'll only use it indoors, the Harman/Kardon is well worth a look. If not, the JBL is the better pick.
The Harman/Kardon Go + Play 3 and the Harman/Kardon Onyx Studio 8 are home Bluetooth speakers that share Harman's stylish design language. Of the two, the Onyx Studio 8 is the more visually arresting, with a wraparound band that doubles as a stand and handle. The Play 3 resembles a more traditional boombox. Ultimately, the Play 3 is the better pick for most people. It gets louder and is also cheaper. The Onyx Studio 8 is a bit lighter, though, so if you'd prefer a speaker that's easier on the arms when moving from room to room, that's the one to pick.
