For different applications, there have been roughly three types of Bluetooth speakers: Bluetooth portable speakers, outdoor Bluetooth wireless speaker, home wireless Bluetooth speaker.

Then how to pick up a high-quality Bluetooth wireless speaker among such a huge speaker system? Just roughly actually pick from the following aspects, you can find a wireless Bluetooth speaker preferred.

First, the sound quality
Two-channel audio speaker unit are far better than the mono speaker in terms of physical structure or cavities.
No matter what the speaker is,of which we need to personally hear the sound just considering some data, if the maximum decibel is less than 80,definitely,it feats as a home speaker. The greater the value of the SNR, the stronger anti-interference ability, the better fidelity.Please pick up those with SNR not less than 70dB.

Second, the functional
Not the more, the better. Some additional features may even become tasteless, some additional features may be tasteless,take some of speakers changing the songs by being shaking for example, it would tend to unexpectedly change the songs. Some are preferable, such as hands-free features radiation protection and facilitating answer the call..
Of course, how the Bluetooth speaker function is closely linked with the Bluetooth version, the current common market Bluetooth version are 2.0,2.1,3.0,4.0. the transmission rate of Bluetooth version 2.0, 2.1 is up to 2Mbps or more. the transmission rate of the latest version3.0, 4.0 jump to more than 24Mbps, the transmission distance is up to 60 meters.The higher the Bluetooth version,the faster the reception rate, the farther the transmission distance,the fewer the power consumption of speaker, the better the speaker sound fidelity.Obviously, the higher version of Bluetooth speakers is better.
Some outdoor Bluetooth speaker features with three anti (waterproof, dustproof, shockproof), which is a very nice.

Third, lifespan
No matter what the Electronics, the longer the lifespan,the better.The endurance capacity of bluetooth speaker is properly at least 8 hours or more.What should be noted is the battery capacity, battery capacity = time×power÷ battery voltage, so the greater the capacity, the longer the battery life. Take the two-channel speaker for example, their power is concentrated between 4 ~ 8W. The battery capacity shall be 1500mAh or more to achieve the desired playing time.

Fourth, portability
For portable outdoor wireless bluetooth speaker. How to choose the size of portable speaker speaker is based on where it would be placed, we need to be able to facilitate all carry in any case. At this point, those rounded are better than those shaped.

Fifth, material
A good Bluetooth speaker is known as necessarily sophisticated materials and sophisticated technology. As far as the Bluetooth speakers crudely made flooding on the market are concerned, many of lead paint are exceeded, these materials would unwittingly affect human health. So you must check the quality inspection certificate when buying . The the the details at the speaker reflects product process, those with neat the key and exquisite analog line and good feeling tend to be not bad.

Sixth, appearance
Difficult to reach, but it is definitely based on your preferences, I prefer to the mini size.

Advantages: installation location diversity,support for large screen mobile phone
Disadvantages: we need use both hands to grip and remove the phone
Sucker easily fall when mist or water droplets on the windshield and block the line of sight

■ manual car phone mobile holder with outlet

Classic manual cell phone holder supports a variety of air-conditioning outlet style excluding those circular or rotatable outlets, you shall make sure the product material, ABS new material is generally the most durable, while picking up those fixed with the outlet and glass sucker products.
Pros: Just use single hand to fix the phone or remove the phone from the car phone stand,it can support 7-inch screen navigation,bottom bracket rotatably supports multiple charging port
Cons: it is not convenient to use when driving
Clip is too flat

■ upgraded semi-outlet car phone mounting bracket

The phone holder would automatically hold the phone, how to work as following: when both sides of the bracket claws open, the front bracket button would pop up, both sides of the claws automatically rebound when you put the phone in the car holder and the backup of the phone press he button of car holder, thereby fixing the phone.
Pros: it is more convenient than purely manual car phone holder,the "paw" front-end clipping the phone with a protrusion can effectively prevent the phone from falling
Cons: it can only support maximum 5-inch screen mobile phone, bottom bracket can not rotate,it does not apply to the phone whose charging port is not at center of the bottom of the phone

■car mobile phone holder fixed with double-sided adhesive

The advantages and disadvantages are highlighted. It can be firmly firmly installed and optionally placed on the car, it is compact and does not take up space. The disadvantage is that it is difficult to remove it once fixed, 3M double-sided adhesive is know for pretty strong viscosity. the phone with radians is invalid.

In addition to the above recommendations, please be careful to buy the following products for safety of life and property,.
■car mobile holder similar to the bracket mounted on the steering wheel

It is actually a patch attached to the center of steering wheel. the backup with no pattern directly attached to the steering wheel, the other side with pattern paste phone. Since the airbags are located in the middle of the steering wheel, it would endanger the safety once the airbag pops up.
■ car phone holder with a skid pad

It is essentially a non-slip pad just with a groove standing the phone rather than a car phone holder. Because the product so versatile and cheap good sales. It has been criticized as those with significant security risk ,the mobile phones can easily be thrown off when we brake or shift .

In short: None of car phone holder is perfect,those hot selling or expensive may be not necessarily suitable for you. In any case, safety is the most important before the selection of our favorite car phone holder.
