Overall Impression

The Sven PS-399 is a portable boombox-style Bluetooth speaker rated at 100 watts. Its volume level is shown via a backlit display, implemented in a way commenters compare directly to the Tronsmart T6 and T6 PLUS speakers. Some users question whether the advertised 100 watts actually gives it more power than Sven's own 50-watt PS-650 model. Opinions on this are split, with some claiming it is more powerful and others disagreeing. One listener who owns an 80-watt Tribit Stormbox Lava says the PS-399 sounds very similar to that speaker. Shoppers also weigh the PS-399 against Sven's own PS-990 when deciding how many units to buy. One comment implies that four PS-399 units cost roughly the same as two PS-990 units.

One user who owns an 80-watt Tribit Stormbox Lava reports that the PS-399 sounds very similar to it. This suggests the PS-399 can hold its own against known boombox-style competitors.

@user-misterBin0007

I have a Tribit stormbox lava at 80 watts. Very similar sound 👍

The speaker shows volume level changes through a backlit display, an implementation a commenter compares directly to the Tronsmart T6 and T6 PLUS speakers. This gives users clear visual feedback when adjusting volume.

Ilia, the volume increase and decrease display with backlight on the Sven PS 399 speaker is implemented like on Tronsmart T6 T6 PLUS speakers and they are the same only updated.

Although the PS-399 is advertised at 100 watts, users disagree on whether it is actually more powerful than Sven's own 50-watt PS-650. Some say it is more powerful while others say it is not, leaving the real output unclear.

@ВладОбидин-ц9з

I have a Sven 650 at 50 watts, will the 399 be more powerful? Because I read what people write, some say it's more powerful, some say it's not, there's 100 watts there.
