I understand on the Sr80. BTW i tried out the XB10 with my Senn HD650 and it went very well. it is really small and being bluetooth no hassles of carrying cables.
Are you using a phone with Aptx HD? I found the XB 10 very grainy
digital sounding, compared to my Samsung S8s headphone out and a venture electronics Odessey. I really wanted to like it because of its convenience,but ended up returning it at the end due to its harshness in sound. With bright Grado, I suspect you will have a earbleed if I am not wrong. I bought it for PUBG gaming, but it didnt work out as the device goes to phone mode while gaming due to ingame chat, which has a radio like sound quality. But I was impressed by the bass and seperation. I am pretty sure it would have worked been better
Again,
been there experience from me is : None of these solutions are really portable, rather transportable. Nothing will fit into your pocket to
walk around. I had FiiO e18, JDS labs c5d, Leckerton audio UHA 6s MK1 & Meridian Explorer II. Upgraditis took me to Chord Mojo now. I travel a lot, and always have the problem of forgetting to charge the DAC. The most convienient of the lot was the Meridian explorer as it wasnt a stack, but rather became a part of the cable. As a spare thing, I bought a VE Odessey. But to say, it is literally the most used device in my list, as its almost equal to having just a cable itself. Though it is an improvement to my phone, I dont know if your vivo orginally have a better sound than s8 which may lower your improvement. Its very smooth with the vocals, slightly rolled off with treble, but has good midbass, though not the tightest. For me, it fits the category of "
good enough",
"can live with it" while being extremely portable than any of the boxes letting me to use it very easily. After reading some impressions on another forum, i bought one only to make sure that they were overhyping. But it turned out to be good. May be you can try that too, I dont think it would hurt anyones pocket.

Limitation is CD quality, but thats where all the Indian music gets at the maximum. But, to my ears, its really smooth, listenable, free from the digital glare of cheap dacs.
Will I need the OTG functionality to support the ifi nano idsd LE too ?
My phone is a vivo 1603 dual sim
An trying to look up the net if my phone supports this...
