My requirements are colorful soundstage, comfort, good quality great battery life along with range and option for cord
Not sure what you mean by colorful soundstage. Generally soundstage is referred as the spatial representation of the music as if played on a stage in front of you. Wider soundstage feels like the music is played by instruments laid across the wide area in stage. Soundstage generally goes with imaging where you can almost pinpoint where the music from partucular instrument is coming from. A wider soundstage is generally preferred than narrower one and you can only make those differences accurately in more audiophile varties - for this you need to go wired ones at your budget.
At your budget 4.4bt in my opinion is good one as others have one good than other like Jbl e55bt and plantronics blackbeat 605 forgoes aptx encoding (which is crucial) Sony xb650bt does not work passively and Skullcandy hesh 2 wireless amplies unnecessary bass overriding the mids amd highs are "screamier".
If you can increase your budget to 8k then see if you can get LSTN fillmore wireless, they are wonderful and thatswhy difficult to find in stock.
