The four bars are just the right amount for us. Its not trash. These USB headphones are very quick to connect and the connection is very strong. It’s a sophisticated scent for sure. i have 4 piercings in each ear so this set is perfect. Bluetooth works very well and the sound is terrific at mid to high levels. Protects the case very well A bit too big. Excellent sound quality for the price, Ive been looking at a lot of comparable speakers and I do think this one has the better bass. Sound:This wking X10 comes with 2 sound modes indoor (bass heavy) and Outdoor (poor Bass and not even Louder than the indoor Just a bit more emphasis on the highs).
