Review on 🔊 BOGASING M4 Bluetooth Speaker - 40W Stereo HD Surround Sound, Deeper Bass, 24H Playtime, IPX7 Waterproof, Bluetooth 5.0 TWS Wireless Dual Pairing Portable Speaker for Home, Outdoor (Black) by Cris Drew

You'll be hard pressed to find a better sounding speaker for $60. I've compared it to Tribit Soundmax and a few others in this price range, BOGASING has a much better and deeper sound presence in 3D mode, almost like Bose, highs and mids are very clear with good bass for most of the music. BUT; That's why I only gave it 4 stars: 1) The only acceptable EQ setting for music is 3D, for some reason the speaker lowers the volume significantly when you switch to mega bass mode, not only that but it loses it also the presence of sound . I think they do some tricks with the DSP to improve the sound, which brings me to #22) Overdriven bass in 3D, songs with loud or muffled bass lines sound a bit distorted at high volume, almost like the speaker is vibrate too much, the bass may become quiet. distorted (the EQ app on your phone can help). Almost as if the DSP were doing its best. 3) Battery life is good, maybe 12 hours at half volume but not 24 hours. Great soundstage most of the time. Don't think you can beat the prices. I need to use the speaker more to get the best sound. I'll update if I can get a 3D setting for better high volume beats.
