The Bose SoundLink Color II is a portable Bluetooth speaker with a square-shaped design. It can reproduce vocals and lead instruments clearly thanks to its well-balanced mid-range. However, its treble range is underemphasized, so the higher frequencies of these instruments may sound dull or veiled. It has an IPX4 rating for water resistance, though we don't currently test for this. Although it doesn't have any voice assistants built-in, it can understand you easily when using the voice assistant from your paired smartphone.
Our Verdict
The Bose SoundLink Color II is passable for music. Its mid-range is well-balanced, so vocals and lead instruments sound clear. However, it really struggles to produce low-bass, and higher frequencies like cymbals might sound veiled due to its underemphasized treble. It also doesn't have an EQ to let you tweak its sound. Thankfully, it can play stereo content without downmixing it into mono.

The Bose SoundLink Mini II Special Edition and the Bose SoundLink Color II have similar strengths, with only slight differences. They're both portable speakers that are similarly well-built. The SoundLink Mini has a more balanced default sound profile, with a less veiled treble response that adds a nice high-end sparkle to vocals and lead instruments. However, the SoundLink Color has a longer continuous battery life, better sound directivity, and an IPx4 rating for protection against water splashes.
The Bose SoundLink Flex is a better speaker than the Bose SoundLink Color II overall. The Flex is better built and has a better-balanced sound profile that can produce a more extended low-bass than the Color. That said, the Color has a longer-lasting battery life of almost 10 hours, though this can vary depending on your usage.
The Bose SoundLink Micro and the Bose SoundLink Color II are similarly performing speakers with a few different features. Although both are incredibly portable, the SoundLink Micro is even smaller, and it comes with a strap that lets you attach it to your bag or backpack. Its soundstage also has better directivity. However, only the SoundLink Color II can play stereo content without downmixing it into mono, and it can get quite a bit louder.
The Ultimate Ears WONDERBOOM 2 is a better speaker than the Bose SoundLink Color II overall. Thanks to its 360-degree design, the Ultimate Ears offers a wider-sounding soundstage. It can also get a bit louder with less compression present at max volume, resulting in cleaner audio at louder volume levels. Additionally, it's much better built with an IP67 rating for dust and water resistance though we don't currently test for this. That said, the Bose supports voice assistants through your smartphone, though its performance isn't very good.

It has an IPX4 rating for water resistance, although we don't currently test for this. It doesn't have an advertised rating for dust or impact resistance. There are three lights on top that indicate when it's on, connected to Bluetooth, and receiving audio input.
The Bose SoundLink Color II Bluetooth speaker has very good controls. It has six buttons located on the top. There's a power button, buttons for adjusting the volume, and a Bluetooth button, which lights up once a device is connected. The play/pause button can be pressed twice to skip a track or three times to go to the previous track. The input button lets you connect a device through the AUX port to play audio, and lights up when in use. If you press the power button, it'fll give you an audio indicator for the battery level. If you press the Bluetooth button, it will audibly indicate its connection status. There's also a light that indicates the battery level, as well as a light that flashes twice when it reaches min/max volume.
The Bose SoundLink Color II has sub-par frequency response accuracy. It really struggles to produce low-bass, which may disappoint fans of bass-heavy music genres like EDM. The mid-range is well-balanced, so vocals and lead instruments are reproduced clearly. However, the higher frequencies of those same instruments may be a bit dark or dull due to the underemphasized treble range. Unfortunately, it doesn't have any sound customization features for tweaking its sound profile. For a similar portable Bose speaker with a better-balanced sound profile, and that can produce a more extended low-bass, check out the Bose SoundLink Flex.
The Bose SoundLink Color has a fair soundstage. It can play stereo content without downmixing it into mono, but its directivity is poor, resulting in a narrow soundstage. There's also an overemphasis in the treble range, so the soundstage may seem uneven from certain angles.
The Bose SoundLink Color has passable dynamics. It doesn't get especially loud, and there are some compression artifacts present at max volume. Because of this, it's not well-suited for use at parties or in large rooms.
This speaker has a good battery performance. Though its battery is advertised to last for eight hours, in our tests it lasted for close to ten hours. That said, battery life can vary according to usage, so user experience may differ. It takes around four hours to charge, and it saves power by shutting off automatically after eighteen minutes without audio input. Using its companion app, you can also set it to shut off after five minutes, 20 minutes, 40 minutes, or one or three hours. You can also turn on/off this power-saving feature by pressing the volume-up and input buttons together.
The Bose SoundLink Color has poor voice assistant performance. It doesn't have any voice assistants built-in, so it uses the voice assistant of the device it's connected to. It's compatible with Google Assistant and Siri, but not with Alexa. Fortunately, it can understand you well even if you're far away or in a noisy room. However, you can't activate it with your voice, and there's no mic mute button to stop the speaker from listening to you.
The Bose Connect app is okay. It's compatible with iOS and Android devices, and you can pair two speakers together to create a stereo pair or amplify your audio content in a large room. However, there's no EQ, so you can't adjust its sound profile.
The Bose SoundLink Color has a 3.5mm AUX port that you can use to connect a device to play audio.
The Bose SoundLink Color II has an excellent Bluetooth performance. You can connect up to two devices at a time, and it has an outstanding range, so it will still receive audio input if you're far away. It has low Bluetooth latency with iOS and Android devices, making it suitable for watching videos. That said, some apps compensate for latency differently, so your experience may differ.
