Current is part of what is used to calculate watts. Watts (W) = Amps (A) x Volts (V) x Power Factor. Amps = Current.
In case you were wondering what is power factor gets a bit confusing to me anyway,
Power Factor = W/VA. Confusing because Watt is part of the first calculation which written out would put W on both sides of the algebra.
Power factor is never more than 1.
I want to welcome my friend @Anfernee to HF and to this thread. Anfernee has been very experienced in portable gears and he has almost all the summit-fi gears. I encourage him to post some of his gear pics here soon!

I wound up getting one of the last few pairs of MDR-EX800ST from that Amazon Japan seller's store. I wanted to be sure and get one partially to have a piece of Sony's audio history, and to have another nice sounding DD IEM. Looking forward to hear how its huge single DD compares to the Penon Vortex and the TZ700.
I had a pair of the MDR-EX1000 waaaayyy back in the day, and have fond memories.

Thanks for the welcome. My name is Anfernee, and I am an audiophile currently living in the US. Due to work reasons, I prefer portable gears, I can take a lot of IEMs with me on a trip, and I don't have to worry about them becoming a burden on me. Maybe someday, I'll consider taking my friend's advice and stepping into unfamiliar territory .
I like copper cables from all over the world because I like a more natural sounding, the only affliction is that there will always be all kinds of difficulties in purchasing.
I haven't published any professional review articles, but I have constructed my own "top gear list" and called them "BIG 12". I generally maintain 12 pairs of headphones and cables as my starting lineup, and they change over time when better challengers emerge; those who are eliminated will be sold; that's my "law of the jungle" for them .
I like to pursue the ultimate sound experience, and this is not limited to the brand reputation of products or their history. You'll see that I might be bashing a brand the day before and then immediately rave about a new product as it comes out and experiences it. I love connecting with people; it keeps me motivated and passionate about the community .
I absolutely agree. When I spoke of source compatibility and amplitude matching, I wasn't referring to all iems, but was making a point that it COULD devalue and underappreciate how one may perceive an iem's full potential.
A lot of my experience comes from single dynamic drivers mainly, although the most memorable experience was through Rhapsodio Bomber MKII, which uses a single graphene magnetostatic driver (exotic specialist iem!).
It costs $4400 and sounded worse than an average tws earphone when underpowered (would heavily recommend an external amp). Experiences like these taught me that not all iem sounds good on mediocre sources and debunks the assumption that iems do not need much power.
There's seems to be an overwhelming amount of misconception trending on social media that you don't need anything more than an apple dongle to hear what an iem is capable of. It pains me everytime I hear someone crusading that amplifiers are meant only for headphones.
After listening to m17 i require desktop amps for my iems now. You really don't know the power or what your iems are capable of without listening to them with desktop level power imho.

In my experience, higher power can "sharpen" up note attacks, given that an IEM has not reached its full potential beforehand. For example, Final E5000 requires a lot of current to sound properly. It is unremarkable and "blurry" on Apple dongle, but sharp and snappy with anything more powerful. You don't need much, just BTR5 or KA3 is fine, though a person who bought this IEM based on my recommendation uses it with his desktop stack.
It should be noted that frequency response measurement at around 85db shows no difference at all between apple dongle and KA3 with E5000. However, the actual listening experience is noticeably different. Noted that E5000 does not sound bad on apple dongle or weaker sources, though, just not quite right.
Another interesting observation is about Shuoer S12. In stock configuration, its attacks are overly sharp on BTR5. So I dampened its nozzle and closed its back vent. Then it becomes slightly soft and pillowy until I kick the BTR5 into high-gain. Perhaps by dampening, I changed its sensitivity or something? Anyhow, I still hasn't heard anything that sounds outright bad without powerful sources.
And high-end IEMs with technologies like LID (64 Audio) or FLAT (Symphonium) should stay the same across sources. That's the point of high-end design, isn't it?
