Buying a Bluetooth Speaker

Bluetooth speakers are convenient and versatile as they can connect to most modern devices. Size, connectivity, and battery life are factors to consider when buying a Bluetooth speaker. The size affects how you carry the unit, the spot to spare, and the volume. The connectivity affects what device you can connect to the speaker and how you connect them; most compact Bluetooth speakers don’t have a physical input. Bluetooth speakers rely on a built-in battery to power the driver, varying depending on size, capacity, and volume level.

About Bose SoundLink Color II and SoundLink Flex

Generally, speakers come in varying shapes and sizes, and Bluetooth speakers are no different. You can find small speakers to hang on a backpack or big enough to host a party. The compact variant like Bose SoundLink Color II and SoundLink Flex is ideal for those who enjoy indoor and outdoor music. These speakers are compact if you want to bring them outdoors and loud enough for casual listening at home. Read also: Bose SoundLink Color II Vs JBL Flip 5 here.

Bose is a well-known audio device manufacturer with many good options. Depending on your preference, the choice may vary. The Bose SoundLink Color II and SoundLink Flex share similarities, such as a rugged body, good sound quality, and reliable connectivity. But the similarities stop here because the two don’t look like they belong to the same line. At a glance, the Color II is best for home use or something relatively light around the house, while the Flex is ideal for more challenging outdoor uses like camping.

It doesn’t mean you can’t take the Color II while hiking, but this speaker is not rated for such applications. On the other hand, the Flex is more versatile, yet we don’t think its appearance is as attractive as the Color II. Sound quality can be subjective, but the two are pretty good for the size, and chances are most people will like their sound delivery. In addition, both speakers also have some features that may be handy such as the Party or Stereo mode if you have more than one compatible speaker.

Bose SoundLink Color II and SoundLink Flex Design

As mentioned above, one of the main differences between Bose SoundLink Color II and SoundLink Flex is the shape or design. The Flex is more rugged, with an IP67 rating and a steel grille. The speaker is coated with a powder matte coating to improve rigidity. However, dropping it on a hard surface will still leave some scratches. The Color II has a rubber coating and arguably looks better, almost like typical smart speakers. The Flex’s speaker places a bass driver at the bottom on the backside, so it is best to avoid placing it on a soft surface.

Bose SoundLink Color II and SoundLink Flex Sound Quality

The most important part of a speaker is the sound quality because it is the primary purpose. Different companies tweak or tune their speakers differently, which can be subjective. We prefer a flat speaker because it can deliver a reasonably accurate sound, but you may have a different preference. We suggest maintaining the volume at a moderate level, especially for the Color II, because the higher settings distort the delivery and make the sound less clear. Small speakers typically don’t produce enough bass, but Bose SoundLink Color II and SoundLink Flex are pretty good.

If you are into bass-heavy music, we think the Flex can better produce the frequency and is more detailed in presentation. The Color II is good for most music genres but not astounding. The separation is one of the best advantages of SoundLink Flex, and the size improves bass delivery.

Bose SoundLink Color II and SoundLink Flex Connectivity

Next, let’s talk about the connectivity side, as Bose SoundLink Color II and SoundLink Flex are wireless speakers that work through Bluetooth. Like most compact speakers, none of these models has physical connectivity, which can be a drawback for some people who plan on using them with a stationary setup. The Bluetooth version is not the newest, but it is understandable because Bose wants the speaker to be compatible with the older models. The performance is decent at a manageable distance.

We don’t recommend putting the speaker in place with many obstructions between the speaker and your audio playback device. One of the best advantages of both speakers is the multipoint connectivity which means the speaker can connect to two devices simultaneously.

Bose SoundLink Color II and SoundLink Flex Battery Life

Battery life is also crucial in Bluetooth speakers because your device relies on the built-in battery for playback. Bose claims the SoundLink Color II lasts 8 hours while the Flex lasts 12 hours when fully charged. In real life, the battery lasts at varying rates because the volume level also affects the playback. The Color II usually lasts slightly over 7 hours at a moderate volume which is pretty good, while the Flex lasts almost 12 hours, which is impressive.

Bose SoundLink Color II Vs SoundLink Flex

The Bose SoundLink Color II and SoundLink Flex are good options for what they can offer. We also want to mention that you can use these speakers in Stereo and Party Modes through the Bose Connect app. The main difference between these speakers is shape and sound production. The SoundLink Flex may look less attractive, but this is the bigger speaker and can produce louder and more detailed audio with better separation. The Bluetooth performance is reliable with minimum interference, but none has a physical input.
