Meet the OPPO Digital Sonica Wi-Fi Speaker

Portable speakers are great for those who appreciate the freedom to change scenery at a moment's notice without leaving the music behind. But not everyone requires the versatility of a mobile lifestyle, and plug-in speakers tend to be richer in features and quality. OPPO Digital, known for creating award-winning products, has made available its latest high-fidelity wireless speaker system. The elegant Sonica Wi-Fi speaker can stream music from a variety of sources either alone, in a stereo pair, or part of a multi-room set-up.

You can't really go wrong with a matte black finish, and the Sonica's artistic styling and compact form allow it to readily complement living spaces. Although it lacks a rechargeable battery, this speaker is still quite portable, measuring only 30 cm long by 14.7 cm wide by 13.5 cm high (11.8 x 5.7 x 5.3 in) at 2.4 kg (5.3 lb). So if you decide to switch up furniture and change layouts, the Sonica easily adapts.

Underneath the curved exterior lies powerful hardware that has been acoustically engineered and tuned by Igor Levitsky, the same designer who helped bring about the OPPO PM-series planar magnetic headphones. The Sonica packs a 3.5-inch bass woofer, two 3-inch bass radiators, and a stereo pair of 2.5-inch wideband drivers. All are powered by four separate amplifiers set up in a 2.1 stereo configuration for the best possible audio performance. And since the company expects users to crank the tunes, the speaker's driver layout and chassis have been designed to minimize vibrations resulting from high volume levels.

In order cater to all the modern methods of audio, the OPPO Sonica features a host of connections. Users can play all the popular formats from PCs/laptops, NAS drives, and mobile devices alike via Bluetooth, AirPlay, or Wi-Fi. Those accustomed to more traditional methods can plug in a USB flash drive or a 3.5 mm auxiliary cable. And with its ability to handle lossless files (FLAC, WAV, and ALAC up to 24-bit / 192 kHz) and stream through Tidal, it's easy to enjoy the high-resolution experience as the OPPO Sonica intends.

Why the OPPO Digital Sonica Wi-Fi Speaker Might Be for You

Although the form and driver hardware is quite impressive, the OPPO Sonica finds true strength with its ability to optimize audio and pair with additional speakers. Room size and speaker location can make a huge impact on how music sounds. Through the Sonica mobile app (free for iOS and Android), users can adjust settings and select from a list of built-in presets. Whether centered in a room, up against the wall or sitting on a shelf, you can make certain that music will always play at its best.

Now if a single OPPO Sonica speaker is good, rest assured that two can make things even better. The mobile app is designed to allow a second speaker to connect in order to create a stereo pair. Whether it's for enjoying a wider soundstage in larger living spaces or improved channel separation for big-screen televisions, all it takes is a few quick clicks.

More speakers can be added and grouped together for multi-room music playback. The Sonica app allows users to control whether speakers play in sync or individually, where each room can have the same or separate sonic experience going on. Given the built-in adaptive antennas with 2.4/5 GHz 802.11ac Wi-Fi compatibility, the OPPO Sonica eschews the time and complexity of wiring speakers throughout the house. Just plug in, power on, and connect speakers to the local network via the app. And that's it — all control is right at the fingertips.

The OPPO Digital Sonica Wi-Fi speaker is available to order via Amazon or the product website. Priced under the $300 USD mark, the Sonica hits that sweet spot for power, portability, and affordability.
