The scope is narrowed, and there are still many options, but I have not done much homework with rich experience. I probably went to JD for a look around, and soon selected it: Sony SRS-XB23. The reason for choosing is simple. Dafa's belief is one aspect, and the other is that he likes SRS-XB12 and Sony recently launched SRS-XB23/XB33. The tangle of the three models is the most time-consuming. The XB12 is too small and has only one speaker. It is mainly used outdoors. But I buy a Bluetooth speaker mainly for home use. Occasionally, I may take my daughter out to play. Maybe I will use a Bluetooth speaker. Of course, this opportunity is uncertain. The XB33 feels a bit big, and is not suitable for taking out. So I finally compromised and chose this XB23, which is of moderate size. If you need it when you go out, you can take it away easily. Does it look like a "thermal cup"?!
Sony SRS-XB23 looks low-key, but it can be said that there are many highlights in details. For example, there is a layer of fabric surrounding the noodles. This layer of noodles is special because it is a double-layer design. The outermost layer of fabric is rough and the interlaced lines are thick; The inner fabric is more delicate, so when you look closely, you will have a sense of hierarchy, without a thin taste. Sony has equipped it with a lanyard, which is thick and slightly elastic, so users can tie it to the motorcycle, backpack, or hold it directly in their hands, and the 580g weight will not bring too much burden.
Sony has made a tough move this time. The SRS-XB12/XB23/XB33 full series supports the unprecedented IP67 waterproof and dustproof! When summer comes, many parents may want to take their children to the seaside lake to cool down. Even if you take them for swimming, it's OK. This level should be the highest level of waterproof and dustproof in digital products, even if you throw them into the water for a bath. By the way, the fabric of Sony SRS-XB23 is not detachable, so to a certain extent, throwing it into water for washing can make up for its inability to replace the fabric.
As a Bluetooth speaker, the most important thing we need to consider is voice. Compared with the previous generations of XB series, the X-Balanced speaker unit mentioned in the official announcement is the most important thing for me. In terms of unit structure, it is not round, but adopts an oval shape (one side is wide, the other side is narrow). It looks like a raindrop shape on the whole?! This shape of diaphragm unit can only be seen on some very high-end HiFi floor boxes in the past, but I never expected Sony to use it on a small Bluetooth speaker! Its advantages are that it can increase sound pressure, reduce distortion, and have higher definition and wider sound field. Don't underestimate this improvement. For a Bluetooth speaker with limited volume, this improvement will bring great changes in the sense of hearing.
In addition, the mica reinforced fibrous cell diaphragm (MRC) is also one of the auxiliary means to improve the sound quality. My understanding of this diaphragm material is limited, so I will not play it. But when I saw it, I immediately thought of the E888 that I started more than ten years ago. I was impressed by the sound improvement brought about by the classic biological diaphragm. I think the MRC diaphragm should have the same advantages.
The appearance of Sony SRS-XB23 seems low-key, but many black technologies are hidden in its body. For example, it has two passive diaphragms at both ends of the column (as shown in the figure below). The model name of Sony SRS-XB23. I believe that those familiar with Sony know that this XB (EXTRA BASS) belongs to the bass series, and there are related products in earphones, earplugs, and audio, Their biggest feature is that they are very distinctive in terms of medium and low frequencies, and even in terms of voice color, they are "Sony". This is consistent with the style and purpose of other XB series products. I will mention the audio in detail below.
All the operation keys are located in the long silicone belt below. Of course, they are waterproof and dustproof. The various functions are clear at a glance. It also supports 100 audio systems connected together at the same time. Rich kids must try it. But for me, my favorite is its Bluetooth reconnection function. If you want to reconnect an ordinary Bluetooth device, you must press the power button for a long time to turn it on before it automatically reconnects. Sony SRS-XB23 doesn't need it. It just needs to press the power button for a short time to connect it to the mobile phone. I'm really satisfied with the efficiency!
Sony SRS-XB23 is a node used to improve the sound quality. In addition to the above physical application of diaphragm technology, it is also quite colorful in the software level. For example, it supports Bluetooth 5.0. Don't think this is not unusual. In the field of Bluetooth speakers, it is really strange!!! In addition to supporting regular SBC/AAC, it also supports LDAC, isn't it surprising?! Sony's Bluetooth audio products within 1000 yuan rarely support LDAC!! There is no doubt that LDAC brings higher decoding capability than SBC/AAC, and the sound quality will be better. However, the premise is that your mobile phone must support LDAC codecs. Now Android 8.0 and above mobile phones support LDAC codecs. Apple users are not so lucky, and can only activate AAC codecs to play music.
Sony SRS-XB23 uses USB C interface for charging. There is no power adapter in the standard configuration, but only a cable with USB C. It doesn't matter. Today's Android phone users all have mobile adapters, which can be used directly. It is worth mentioning that the built-in lithium battery capacity of this Bluetooth speaker is up to 2700 mAh. It can be fully charged after 4 hours of charging, and the battery life can be up to 12 hours. Basically, it can be played continuously throughout the day without any problems!
[Subjective listening experience]
I thought that Sony SRS-XB23 should not have enough drivers to improve its endurance. However, the fact is just the opposite of QIA. As long as it is turned to a moderate loudness, the whole sound pressure is good enough, and there is no sign of weakness.
In terms of specific sound performance, I first listened to Nakajima Meijia's divine song "Once I Wanted to Get Rid of It" with it. I heard that when this song was released that year, Japan's mortality rate dropped sharply, which is a very inspirational music. As a fan who is not so keen on Japanese music, I started to know Nakajima Meijia from this song. Isn't it a bit hard to say haha!! Well, it's not important, but the important thing is that the sound under Sony SRS-XB23 can bring abundant energy and strength, especially the low-frequency part, which has a deeper dive and greater dispersion. Even in this case, the low-frequency details are still at a glance and there is no confusion. This effect is shocking to me. It can be said that the high-quality low-frequency Bluetooth speakers are few competitors! In terms of midfrequency, Nakajima Meijia's voice is quite prominent. The knot image is healthy and complete, and the fineness is good. There is no obvious sense of distortion, and even a little bit of HiFi flavor. Its low frequency never deliberately suppresses the performance of midfrequency and high frequency. The voice and instruments of midfrequency are quite brilliant, and the outline of the lines are clear and recognizable, For fast food music lovers like me who love popular voice, this is just right. The high-frequency part is not so bright, but it is also standard. The advantage is that the dental sound processing is very smooth, delicate and durable. The disadvantage is that it is slightly stuffy. There is still room to improve the transparency.
In addition, dynamic and transient response is also one of the advantages of this small Bluetooth speaker. I never expected such a small speaker to bring a sense of surging momentum, but after listening to Jay Chou's new song Mojito with it, my idea was immediately subverted, The dynamics of this product can have such a significant height difference. If it is used to listen to "Mojito", you can clearly feel the lively melody and the ups and downs of the main and secondary songs! In terms of transient response, Sony SRS-XB23 belongs to the level of vividness and power sense. In short, it is used to demonstrate the popularity of human voice. Its transient and dynamic response is enough. It can listen to fast-paced songs and even let you dance with each passing beat. This lively sense of rhythm is very satisfying to me.
Summary
To sum up, I have never regretted Sony SRS-XB23 since its inception. Sony's unique tuning flavor can bring a lot of fun to my life. I often use it when I wash, mop the floor, code words and go to the toilet. Recently, I am particularly fascinated by the story of Du Yuesheng in the Himalayas. From his birth to his first entry into the Qingbang, the finishing effect of the voice seems to be the voice effect in the cinema, which is very impressive. Dafa is really my heart! Of course, there are many other options for Bluetooth speakers, even cheaper ones. But I think that if you have a little pursuit of sound quality, Sony SRS-XB23 is probably the most worthy one in the price range of 1000 yuan. Its appearance is low-key, its functions are simple, and its application scenarios are rich. The key is the core: sound. I believe you will not regret hearing it!
