The first AV device that comes to mind as an AV device that you want to accompany your summer leisure is a Bluetooth speaker that is waterproof and can be taken out for active leisure activities such as the outdoors. In late June, when I was interviewing for the production of this article, midsummer days continued in the metropolitan area, and when I started interviewing in my garden, I couldn’t stand the heat, and the Bluetooth speaker for interviewing was also in the water of the bucket. I threw it into the water, played with Jab Jab, and then started playing music.
In such a hot summer, the Bluetooth peaker is a gadget that you can play outdoors or around the water. The biggest feature is the ease of carrying it anywhere. If you have a smartphone, you can boost the sound and listen to it. The Bluetooth speaker is a summer staple.
BOSE, JBL, Sony, and the three major audio brands that represent the world dominate the top share of Bluetooth speakers. The theme of this time was to explore the difference between such standard brand Bluetooth speakers.
The first thing to keep in mind is the size and market price of the Bluetooth speaker. Basically, the larger the housing size of a speaker that plays music, the more it contributes to sound quality, which is particularly advantageous in terms of bass reproduction. The current selling point is about the size of a 500ml PET bottle, and the budget is in the 10,000 yen range. IP67 waterproof and dustproof specifications that can be actively used outdoors are standard.
If you pick up products that meet these specifications from the products of the three major brands of BOSE, JBL, Sony and Bluetooth speakers, the following three models are applicable.
It may be rough to treat BOSE, JBL, and Sony as rivals because the prices are close, but the specifications are also similar. The weight is 580g for BOSE, 550g for JBL, and 580g for Sony, so the difference is only 30g. As for the toughness specifications of dustproof and waterproof, BOSE is equivalent to IP67, JBL is equivalent to IP67, Sony is IP67, and so on, but Sony is also rustproof. The continuous playback time, which indicates battery performance, is exactly the same for all three products, BOSE, JBL, and Sony, in about 12 hours.
After that, there are differences in speaker design and original technology for each product, but what is worrisome about Bluetooth speakers is the difference in sound quality. This time, I paired it with an iPhone and listened to the same song and compared it. As for the sound source, I listen to two songs, BTS “Dynamite” and YOASOBI “Sangenshoku” intensively.
Bose-oriented BOSE, sharp JBL, balanced Sony
First, I tried listening from BOSE “SoundLink Flex Bluetooth Speaker”. Speaking of BOSE, it is a classic brand that can be called a pioneer that expanded the Bluetotoh speaker market with “SoundLink mini”. The “Sound Link Flex Bluetooth Speaker” can be placed vertically or horizontally, and has a function to automatically correct the sound balance using the unique “Position IQ technology”. However, it does not seem to assume that the main body will be installed vertically like a bottle.
When I actually listen to the sound of BOSE “SoundLink Flex Bluetooth Speaker” … It seems to be a classic brand, and it seems that it is good at reproducing the rich and full space of the deep bass that was the model of Bluetooth these days. Both BTS and YOASOBI have natural singing voices in the mid-high range, but should they be called bass-oriented in terms of balance? Even if you move the main unit vertically and horizontally due to the correction of “Position IQ technology”, the way you hear the sound does not change, but there seems to be a momentary lag in the operation. In addition, it is the only model among the three models I tried this time, and when I pulled it up from the bucket and played music with water dripping, the sound was muffled by the water droplets, so you should be careful about cases where it gets wet all the time.
JBL “FLIP6” adopts a tubular body (horizontal installation is also possible) suitable for vertical installation with the main body upright. JBL is a long-established brand in the world of audio, but recently it has been very successful on the Parisi route, which is more like the West Coast of the United States, where you can play and dance by the poolside. Functionally, there is nothing special other than connecting multiple units in a chain, and it is one of the simple routes.
I actually listened to the sound of JBL “FLIP 6”, and after ensuring a sufficient amount of deep bass, the sharpness of the dynamic rhythm and the pleasantness of the beat are outstandingly good. At the same time, the singing voice and male and female vocals stand up sharply. When it comes to the sharpness of bass and treble, it is a type called Donshari, but there is no unpleasant feeling in the high range, but rather the expression of singing voice and melody is clear and dynamic, and it is exquisite as the sound balance of the Bluetooth speaker. Even if it gets wet with water, it has the power to fly off with a passive radiator. It’s a simple and highly complete Bluetooth speaker.
