Fosi Audio IM4 Open‑Back Wired Earbuds – All‑Day Comfort for Work, Commute, or Home

Not really there

Hello Fosi team, I will be as honest as I can in this message and I hope that it will matter what my opinion is, although I am not a musician but i love music . Unfortunately if we compare the quality of the sound between the IM4' s and for example the samsung AKG earbuds, which I bought for 18 euros, we find out that the big price difference is unjustified. Ok , I know the production process, the materials used and the entire package it has a cost , but still the frequency range is almost the same and the sound quality also. I am satisfied with the DS3 DAC and IM4 combo , but , yeah, still the price was to high for the entire experience that is offered. Comfort wise they are ok. I find a little discomfort with the right IM4 , on the outer ear, but probably that is because the shape of my ear , or I don't know. What I love about them is that i do not get fatigued wearing them and i can go for more than 3-4 hours of constant listening. I also like mixing music with them. Maybe after some months i could come back and make a more in depth review of the products, I hope that things will be better until then. Please do send me another form to fill out in few months. Thank you! Liviu

Shipping experience was horrid but the headphones are so far great. I ordered them on july 8th and the last update on the fedex website was on the 14th. Delivery was scheduled for the 17th but it arrived on the 22nd with zero updates whatsoever.

Legitimately the best IEM I have owned

Literally the soundstage is amazing. Being able to tailor two different stages via the replaceable nozzles is by far the most beneficial feature of this IEM. Not to mention the ceramic housing of these makes it feel like such a premium quality IEM. The only other IEM I own that has even the slightest premium feats of the IM4 has been the BASN Metalin IEM.
