![]() ![]() Still, the Sync 20+ offers a marked improvement over tinny laptop speakers as long as you don't mind watching movies in mono in a small room area. Setting the equalizer to "Bass" in the Poly Lens app does help improve things considerably, but the monaural experience can be off-putting for some. For instance, we observed that a lot of detailing in the audio was missing while playing back the school bus action sequence in Terminator: Genisys or in the Chateau fight scene in The Matrix Reloaded. The relatively lower bass response means that movies may not be as enjoyable as music on the Poly Sync 20+, particularly with action sequences in multichannel audio downmixed to mono. All measurements were taken with the Sync 20+ connected to the PC via USB. We found this to be largely true while testing with lossless FLAC tracks such as Belle from Notre Damde de Paris, Hotel California by The Eagles, and Child of the Universe by Ambra Angiolini, which have distinct vocal and guitar signatures. Thus, some of the finer nuances in the tracks including voice and instrumentation can be reproduced much more faithfully than your average laptop or smartphone speaker. While playing back a 1 kHz sine wave, we observed very low total harmonic distortion (THD) and background noise. In our measurements, the Sync 20+ yielded a signal-to-noise ratio (SNR) of 51.4 dBFS, which is somewhat on the lower side but does not affect casual listening much. That being said, the 40 mm loudspeaker augurs well for higher frequencies, particularly the mids and vocals. As you can see in our pink noise diagram below, the Sync 20+ can reproduce distinct bass only from around the 52 kHz mark. The passive radiators ensure enough bass for casual listening, but do not expect it perform great at very low frequencies. Still, the overall sound profile is quite decent. Poly confirmed to us that it is not possible to pair multiple Sync 20 units in stereo mode. However, you will only get a monaural experience since the device sports only one loudspeaker. ![]() The Poly Sync 20+ also doubles up as a neat listening companion to your smartphone or laptop. If you like a fully hands-free, natural talking experience while moving about your home or small office space, the Poly Sync 20+ will ably fit the bill. The microphone can easily pickup voices while walking from one corner of the room to the other without having to shout your lungs out. In our testing, we found that to be largely true. Poly specifies that the microphone has a pickup range of up to 2 m and is ideal for a 4 m x 4 m room size. The added bonus is that the Sync 20+ supports noise and echo reduction, which should result in call quality better than your average laptop or smartphone microphone.Īnother nifty feature of the Sync 20+ is that the steerable microphone array can be quite sensitive to your voice across the room. That being said, the quality is more than sufficient for regular phone calls and online meetings. The microphone frequency response is rated between 100 Hz and 6.7 kHz, so do not expect too much of a bass effect in the voice. Callers on the other side report good voice clarity with no perceivable clipping or disturbances. The Poly Sync 20+ makes for a good calling device when connected to your phone or PC. The four rubber feet ensure a tight grip on the surface without skidding. The USB cable itself is not detachable from the device, though. The base sports a groove for neatly winding and tucking away the USB cable when not needed. ![]() The same lighting cues are also offered by the BT600 dongle. The bar glows blue upon a successful connection, green during calls, and red when the microphone is muted. Poly also offers the Sync 20 as a Microsoft Teams-certified version in which case you will also find a dedicated Teams button on the panel.Ī status light bar glows along the length of the touch control panel when the device is connected to the source. The top of the device is completely occupied by the speaker area, which internally houses a bass reflex system with dual-passive radiators, a 40 mm loudspeaker, and a steerable three-microphone array.Ī touch-sensitive control panel with dedicated buttons for call/answer, microphone mute, volume up and down, and a programmable "Rocket" button is present below the speaker area. The smart speakerphone is IP64-rated for dust and water resistance. The Poly Sync 20+ is portable and well-built. ![]()
