Top 10 Best Bluetooth Speaker Under 100 Dollar

Depending on your needs and the type of music of each person, we can choose the appropriate speaker. These top 10 are the most popular products, suitable for most users.

How To Choose a Good Bluetooth Speaker

Bluetooth speakers - like other electronic devices, also have a lot of important specifications included. However, to fully understand the meaning of speaker specifications is not easy, non-specialists easily fall into confusion before the technical data sheet, causing many difficulties for ordinary users when buying. shop. Today,I will help you understand thoroughly some of the specifications recorded on each speaker so that you can analyze and find yourself the most satisfactory speaker.

Instructions for viewing the basic specifications of the speaker

After choosing a speaker with a style that suits your needs and purposes, the next thing you need to pay attention to is their specifications. Because these parameters will largely determine the sound quality as well as the durability of the speaker you are interested in.

Maximum power

The first parameter that the manufacturer usually gives is the maximum power of the speaker. The unit is W (watt). That is the parameter that speaks to the maximum power consumption of the internal driver. This parameter is often confused with the loudness of the speaker. But wattage doesn't exactly determine how loud a speaker is, they really just tell how much power the internal driver consumes.

The maximum power of the speaker is the sum of the maximum power of the drivers inside it.

Example: The Marshall Kilburn speaker has 25W of power coming from 3 internal drivers, 1 15W woofer and 2 5W tweeters each.

Next example: The Harman Kardon Onyx Studio 4 speaker has a peak power of 60W from 2 tweeters and 2 woofers, each with a capacity of 15W.

Frequency response

Frequency length is the next important factor when considering a speaker's specifications. Basically, the wider the frequency range of a speaker, the better. The lower the frequency range, the better the speaker's ability to play bass, and vice versa, the larger the frequency range, the higher the highs of the speaker will tend to be. Information about the frequency range of the speaker is also recorded in great detail by me in the Specifications section of each speaker.

For example, for the Marshall Kilburn speaker, the frequency response range of the speaker is 62-20000Hz. That is, basically the most bass Marshall Kilburn can show is 62Hz, the highest is 20000Hz.

Theoretically yes, but in practice, for small speakers, the frequency range is quite for reference. For example: According to the specifications given by the company: JBL Boombox's frequency range is 50Hz - 20000Hz, the frequency range of Harman Kardon Go + Play is also recorded similarly to 50Hz - 20kHz. But really, according to music players, Go + Play still has a much better bass than Boombox.

Speaker battery life

For speakers with batteries, the next thing you need to pay attention to is the battery life and charging time of each speaker. In fact, to find the most accurate number, you should use the formula:

Actual battery life = Manufacturer announced battery life / 2

Manufacturers often make commitments "20000 mAh battery capacity for up to 24 hours of music playing time". In fact, with less than ideal conditions, the speaker's playing time is only half that amount.

In addition, the time to fully charge the battery is also a remarkable thing. Some speaker lines, in addition to fully charged mode, also provide fast charging mode to make the speaker more convenient to use.

Water resistance

The IPX rating is an international standard for protection against ingress of water (waterproof) on electrical and electronic equipment in general and wireless bluetooth speakers in particular.

To find out how waterproof a device is, consumers will look at the digits behind the IPX code. Specifically:

Water Resistance code:

  • IPX0 Not water resistant.
  • IPX1 Resistant to vertical drops of water.
  • IPX2 Resistant to dripping water when the device is tilted up to 15 degrees from its original position.
  • IPX3 Protected against water spray at an angle of 60 degrees.
  • IPX4 Protects against splashes of water in any position.
  • IPX5 Resistant to low-pressure water jets for at least 3 minutes.
  • IPX6 Resistant to high pressure water jets for at least 3 minutes.
  • IPX7 Protects the device from being submerged in water up to 1 meter for 30 minutes.
  • IPX8 Protection from the effects of immersion in water up to 1 meter (depending on manufacturer).

Some bluetooth speakers have extremely good water resistance up to IPX7, for example some JBL speakers like JBL Charge 4, JBL Link 10, ... Or like Marshall's Hit the road speakers are often equipped with anti-corrosion standards. IPX5 water like Marshall Stanmore II,...

Connect ability

For wireless speakers, bluetooth connection is considered a very default feature, so basically, we don't need to care about them too much. Bluetooth is a wireless connection standard that connects different devices and transmits data over short distances

For higher bluetooth connection technology, for example Bluetooth 5.0 - devices that will use this new technology will be able to transfer data twice as fast (compared to bluetooth 4.0). Not only will the pairing process be faster, there will be less delay and minimize the amount of audio "dropping" on the line.

Speaker Marshall Stanmore II is one of the speakers equipped with the most modern bluetooth connectivity available today, bluetooth 5.0.

In addition, the speaker's connectivity is also supplemented with its own apps and features that support access to the music store of iTurn, Spotify, Chrome Music, ... conveniently.

Speaker configuration

The last important thing, the sound quality of the speaker will depend a lot on the internal hardware configuration, depending on the drivers, the size of the sound chamber, ... This part is quite complicated and requires a fair amount of knowledge. strong in sound, but surely I will come back and bring another detailed article to analyze speaker sound quality based on the configuration and size of the drivers, resonator…
