SVEN Speakers for Mobile and Portable Devices, www.3dnews.ru
Though the devices produced under SVEN trademark are quite varied, music speakers are still making the overwhelming majority in the range of the company’s products. Because of the onrushing advent of mobile and portable devices like smartphones, tablet PCs and ultrathin notebooks unable to provide sound of decent loudness and quality, it’s worth turning our attention to the line of SVEN speakers designed for this kind of devices giving their users complete mobility.
One of the most notable accessories of the kind is SVEN Boogie Ball R distinguished with its modest dimensions of 50×50×35 mm and only 56 g in weight. The speakers have a built-in lithium-ion battery (3.7 V, 300 mА·h) providing its 7-8-hour autonomous operation and used as a mobile charger via a micro USB port. Its output power is 2.4 W, which is pretty much for such modest size. The 3.6-mm drivers are not shielded.
Due to its design, the stereo sound spreads in all directions, and to improve its quality, the Bass Expander technology enhancing the lows is used. Any device equipped with a 3.5-mm mini-jack can be used as a sound source. The speakers come with a 2.5-mm adapter and a micro-USB—USB cable to charge the built-in battery. The device is available in black, navy-blue and red.
SVEN PS-36 portable system has several curious design features. It consists of a pair of portable and easy-to-carry 3W drivers with 50-mm diameter equipped with magnetic holders turning them into a single piece. The foldable design of the model protects the speaker system from being damaged when carried.
The system is powered via a PC USB port or the included power adapter operating with 4 AA batteries ensuring 8-hour independent work. Each speaker is magnetically shielded; its dimensions are 120×70×45 mm, and total weight is 267 g (not including batteries).
The concept of SVEN PS-35 differs essentially from PS-35 in its design but not in technical specifications, so it’s needless to repeat them. Each speaker is equipped with a 50-mm driver and almost cubic in shape and transformable, which is intended to combine two features: compact size for carrying and ergonomic design for operating. By rotating the upper part, you can change the sound direction according to the usage conditions and user’s wish.
Along with USB power supply, you can install three AA batteries for 8-hour independent work into the active speaker which also has a volume control wheel, AUX input and a power on/off button. Each speaker’s dimensions are 75×70×65 mm, and the total weight is 372 g (without batteries).
SVEN OMNI portable speaker system duplicates the shape of the integrated drivers, has a small tilt ensuring the omnidirectional sound field, and protruding round grille on the diaphragm. The diameter of the speakers is 132 mm, and their height is 54 mm. The total weight of the set is 600 g.
Each speaker has a 50-mm full-range 2W driver with a neodymium magnet. The enclosure is passive radiator expanding the range of frequencies reproduced by the speaker. The passive radiator is located at the bottom of the devices. The active speaker has a bridge amplifier with power 4 times higher than that of AB class amplifiers, and a volume controller. The speakers are powered via a USB port or a 5V adapter.
Beside black-and-gray, the speaker cabinets come in yellow and apple-green. It’s notable that when the system is on, the base of the cabinets and the volume controller is backlit.
SVEN 355 is the simplest compact solution for a laptop. Aluminum magnetically shielded diaphragms with 44-mm diameter and 2.5W power are enclosed into black plastic cabinets and have bass-boosting passive radiators. The power is supplied via USB, but the sound is transmitted via a separate 3.5-mm mini-jack. The device uses the same kind of passive radiator as OMNI. The novelty is equipped with a volume control wheel. The size of each speaker is 130×75×68 mm, and the weight of the set is 473 g.
But if we seriously discuss the sound quality and volume, hardly any portable desktop speakers would compare to headphones in this respect. Their range in the variety of SVEN products is quite diverse by type and design. Let’s have a look at some headphones the company places special value on, admitting their unique features, as well as high sound quality with deep bass.
SVEN SEB 12 WD model has wood as case material, which improves acoustic properties of these in-ear headphones with a 10-mm diaphragm.

Among full-size headphones, we can single out SVEN HP 50 WD in retro style with wood imitating design. They have comfortable ear cushions, an adjustable headband, and produced under a special SVEN technology – Extra Bass Volume, providing deep and taut bass.
