Altec Lansing HydraMotion 2.0 EverythingProof Wireless Portable Bluetooth Speaker, Light Gray Royal Blue, IMW1102-LGRYRYB

I wanted to replace my 4 but I've noticed that the new flips are mono only, the extra bass was nice but no stereo so the instrument separation was mud sounding and the hydra jolt was stereo but it was lacking in the bass department and hurt my ears at loud volumes, I saw the hydramotion 2.0 was cylinder shaped, had stereo and boy it blows my flip 4 out of the water, it has clears highs and decent bass and doesn't hurt my ears at higher volumes and has full sound, the sound is amazing what can say, sounds way more balanced than the hydra jolt 2,a lot warmer sound, id recommend going into developer mode and search for Absolute Volume disable it then restart your speaker turn your phone volume to a hundred percent and that way you can control you speaker volume separate from the phone so you can get the most volume, and I say this because some people in the complained about the volume being to low, its your phone thats being janky it sets the volume of the speaker to low because there is a mismatch with absolute volume control so running the phone volume separate from the speaker fixes this. highly recommend this speaker and it could go toe to toe with the flip series even though they when in the bass department but can't match it in the sound stage department.
