Along with the portable speaker JBL Charge 2, the kit contains only a power supply, replaceable plugs and an instruction manual. No additional accessories are implied.
Charge 2 design
The appearance of Charge 2 is practically no different from the previous model and is focused only on mobile and widespread use. The original JBL Charge 2 looks like a cylinder, making it easy to attach, for example, to a bicycle frame using a standard holder.
A large battery negatively affected the column's weight: it exceeded half a kilogram. Perhaps this characteristic of JBL Charge 2 is the only one that can cause inconvenience to the user.
The body is mostly made of rubberized plastic. One of the distinguishing characteristics of the JBL Charge 2 is the well-thought-out shape of the case, in which the speakers are covered with plastic grilles recessed into the base material. The full-range loudspeakers are located on the side of the manufacturer's logo, while the second grille is installed only for symmetry in the design.
At the top, the grilles are separated by a control panel equipped with backlit keys. The buttons are not touch-sensitive, as is customary on modern devices, but are depressed. Such a characteristic of JBL Cherge 2, as the absence of protruding parts, is a good advantage, especially if the acoustics are used in extreme conditions. You can distinguish the buttons tactilely, blindly, the volume swing is embossed. There is a small hole next to the tube - a microphone.
Passive radiators are located at the ends of the column. They are not protected by anything, but at the same time they are deeply recessed into the case, so that, as users especially note in their reviews on JBL Charge 2, they are not affected. During operation, the emitters vibrate very noticeably.
On the right side of the case, there are small legs that allow you to set the speaker in an upright position. In the JBL Charge 2 acoustics, the characteristic that marks it is a special indicator located under the volume control buttons.
Three connectors are hidden under the grill located on the back of the speaker: for charging third-party devices - a high-current USB input, for connecting sound sources - TRS 3.5 mm and for charging a gadget - microUSB.
Due to the elongated base, the column does not have sufficient stability, which makes it easily topple over. Despite this, in the reviews, users note that this does not threaten the acoustics, since after several shakes, its speakers remain directed upward.
Column Measurements
Many users in their reviews carried out various tests of the characteristics of JBL Charge 2. For this class of acoustics, the uniformity of the frequency response graph is acceptable at intervals from 75 Hz and 2 kHz and from 5 kHz to 12 kHz. It should be noted separately that the schedule reaches an acceptable level quite early.
The maximum sound pressure, which is often measured by specialists, is one of the important parameters of loudspeaker systems. The check is simple: the column is placed on a chipboard table in such a way that the main speakers are directed towards the measuring microphone. At a distance of one meter from, a measuring microphone is attached at the same height and connected to a spectrum analyzer.
Synchronized with a smartphone with setting the maximum volume level. During the test, the average dBA readings are recorded for half a minute of sounding in any player of the so-called pink noise.
According to the results of the tests carried out, we can say that the portable acoustics of JBL Charge 2 are practically not inferior to their counterparts in terms of sound quality and volume.
Sound
JBL speakers are distinguished by excellent sound quality: even the fake JBL Charge 2 sounds more open and louder than their original competitors, for example, the Sound Blaster Roar. The lower and upper registers are more detailed, which allows you to convey the nuances of the sound of various musical instruments.
The JBL Charge 2 manual mentions such a function as simultaneous synchronization of up to three third-party devices. The gadget that was connected first remains the priority: the rest do not enter until the playback on it is finished. When you press the corresponding key, priority is transferred to the device that is currently connected to the speaker.
The disadvantage of the JBL speaker as a wireless headset is the reduced microphone sensitivity: in order for the interlocutor to hear at least something, you need to move close to the speaker. Despite the fact that the maximum volume is not high, the timbre of the voice is broadcast without any distortion.
The maximum volume level is sufficient for sounding a room with an area of 20 square meters. The JBL speaker at a volume of 50-70% copes well with any genres and compositions, delighting listeners with clear high notes, detailed bass and a good middle. This gadget is ideal for both background sounding and creating a working atmosphere.
JBL Charge 2 is almost the first speaker on the acoustics market, capable of playing heavy compositions at a fairly high volume level. In detail and depth of low frequencies, losses occur only at maximum volume. Despite its compact size, the speaker accurately and efficiently reproduces many genres of music. Controversial compositions are best played out at an average volume level.
Separately, it is worth mentioning such a feature of the Charge 2 as a fast connection via Bluetooth - a pair is created in almost a second, while analogs need five to seven seconds to connect. The JBL Charge 2 instructions indicate the battery life - 12 hours, during which music playback is carried out without problems. The mentioned time can be reduced several times if portable acoustics are used as a charger for a tablet or smartphone.
Acoustics from Harman were not only improved by the manufacturer, but completely redesigned, which made it possible to create one of the best speakers in their class and at such a price on the JBL Charge 2. The gadget has good bass, plays music at the maximum volume level quite well for its category and comes with a capacious battery that allows you to charge third-party devices. The average price of JBL Charge 2 is 7 thousand rubles.
Autonomous work of the column
At an average volume level, when connected to a tablet, the JBL speaker can work for 18 hours, after which the battery is completely discharged. The large, high-power battery allows the JBL Charge 2 to perform well in battery life compared to similar devices in the same price category, slightly inferior in this indicator to some other portable speaker systems.
Connection options
You can synchronize the JBL Charge 2 portable speaker with any devices and gadgets using a Bluetooth connection or using a 3.5 mm cable. Unfortunately, such a cable is not included in the kit - you will have to purchase it separately. For connection, the Bluetooth 3.0 profile is used - a high-speed high-quality connection.
Distinctive features of acoustics
As mentioned above, the main feature of JBL Charge 2 is the mentioned Social Mode, that is, the ability to charge third-party gadgets. Using a standard USB cable, you can connect any device to a portable speaker - smartphone, tablet, player - and charge it while listening to music. This function is very beneficial and useful and will play a good service in situations where it is difficult to access the network to fully charge the gadget.
Summary of the review
Throughout the years of its existence, portable acoustics of the JBL brand have made a good impression on users, striking with their quality and excellent sound. Coupled with an original and unique design, the Charge 2 significantly outperforms its main competitors in the same class and price range. The ability to charge third-party devices can help the user out during travels or long walks, which has been repeatedly noted in numerous reviews on JBL Charge 2. The cost of Charge 2 with such a set of functions and characteristics does not look so high: the column may well compete with the expensive products of famous brands, bypassing many of them.
JBL is a company with 139 products for car audio and home electronics. It enjoys well-deserved recognition among professionals and amateurs of high-quality audio. Every year, the line of JBL subwoofers for the car is replenished with new models, they become better, louder, more voluminous, to which the consumer sector is sensitively responding.
Development history of JBL subwoofers
Since the introduction of premium automotive loudspeakers in the 1970s, JBL has been actively involved in the development of converters and amplifiers for the implementation of Hi-Fi systems in cars, making the most of its rich engineering experience. Cars have changed markedly since then. Music media and customer habits have changed even more. In the course of this process, the demand for quality loudspeakers, subwoofers and amplifiers as a key element in the reproduction of quality sound has grown.
JBL brings this refinement to life in all its beauty, leveraging technology that has been conceived for studio monitors, concert speakers and premium home equipment.
JBL car subwoofer technology
The patented SSI ™ smart impedance technology with an exclusive impedance switch allows you to have one versatile line of subwoofers and choose the optimal impedance for your system based on the number of subwoofers in use. In addition, you will certainly appreciate the possibility of a simple extension of the system for the future.
The suspension ensures that the diffuser is securely fastened, even with a long stroke. There are a number of reasons why JBL uses rubber and butyl rubber mounts on all car speaker systems.
The first is durability. Suspensions made of polyurethane foam deteriorate over time and fail under the influence of moisture, ultraviolet radiation and humidity. Rubber suspensions, in turn, are immune to these influences. The second reason is that rubber and butyl rubber suspensions provide optimal cone attachment and absorb unwanted anomalous distortions that occur near the diffuser edge. Thus, the advantage is a reduction in the level of distortion and an increase in the reproduction power. This results in a higher sound quality, clear and loud reproduction of sound at low and medium frequencies without any destructive effect on the suspensions.
All JBL subwoofers are designed to operate over a wide range of cone offset, and progressive stiffness centering washers are indispensable. This centering washer maintains the suspension stiffness consistently and throughout the reel's range of motion. The larger the amplitude of the coil movement, the higher the efficiency of its work!
Without this level of control, the diffuser can deform, leading to unwanted distortion at high power.
JBL cabinet subwoofers
The patented Slipstream bass reflex in JBL enclosed subwoofers eliminates the annoying background noise generated by high air currents in the bass reflex tube. Compared to conventional bass reflexes, a key advantage of the patented Slipstream technology is the ability to achieve higher volume and eliminate distortion. This makes your system sound louder and delivers clearer bass.
