JBL Tune 710BT vs
AKG K371:
710 is wireless as well as wired. Pads are a bit on the small side and being pleather get sticky and hot.
The sound is bassy/warmish and with elevated treble up top.
Mids sound quite good and are slightly on the laid-back side. The treble has some sharpness but does have a soft ‘texture’. There is no sharpness to the sound. This headphone has (tastefully) elevated but somewhat muddy bass. On the go a little extra lows is welcome. This also works well with most pop recordings. Those looking for realistic hifi sound which sounds good when playing high quality recordings on higher quality headphones may well be disappointed as the bass is too much and not high quality. Those looking for well extended and tight bass must look elsewhere. Youngsters enjoying bass will like it. Not suited for real bassheads.
A bassy and smooth sound without harshness where all instruments sound natural.
K371:
It has a neutral tonal balance. This means all instruments sound ‘natural’ or at least are at the right level. This does not mean all people will perceive it this way.
Those that want to use this headphone as a monitor or even to check their mix on a headphone can use this headphone and get good results.
Is this the perfect headphone ? No it also lacks here and there a bit and while tonally correct it isn’t a real high flyer when it comes to finer details and smoothness in the treble.
Bass is on the correct level (so NOT for bassheads !) and sounds quite good providing you have a good seal. Mids sound ‘open’ and ‘forward’. There is no cuppy sound and the bass and mids are integrated nicely. Those preferring ‘laid-back’ sound should look elsewhere.
The upper treble and highs is not the K371’s strong point. It certainly isn’t performing poorly though. There is good clarity and treble is not over the top and there is enough ‘air’ and ‘detail’. The K371 doesn’t do things wrong here, it just doesn’t excel.
Those looking for a ‘soft’ and ‘smooth’ audiophile type of treble may be disappointed. Treble is slightly on the coarser side but certainly not ‘grainy’. No sibilance nor shouty sound and treble is at the correct level. Just not super refined.
Those looking for a closed headphone with a neutral sound should definitely audition the K371.
Mechanically not the best headphone. Cable is microphonic.
SRH440:
The sound is ‘warmish neutral’ with sharp treble up top. This is good for monitoring because you can pick out details more easily. For music enjoyment the treble is a tad too sharp at times. Bass doesn’t go deep but sounds full and accurate.
Mids have a warmish neutral character. The sound is dynamic. Treble is not ‘refined’. Bass quality is better than the SRH840 which is a bit bassier but also muddier/less well defined.
