ISN Audio - H20

I really didn't know anything about this brand. While doing some research, I found Penon Audio, and therefore Isn Audio and Leteciel. They're not very well-known in the US market, and there aren't many reviews. They arrived from Hong Kong today, and it was a big surprise how well-made and tuned this Isn H20 IEM is. I didn't think that for $70 I'd find such good, quality bass and a very pleasant frequency extension in general. Can someone who has the Leteciel Shark tell me what the audio signature is like and if they're worth it? If it's a good option at $109? I love the Isn H20. I'd really like some Penons, but they're very expensive. Any recommendations, please.

I have the ISN H20 and they're wonderful, better than many more expensive IEMs. My absolute favorite is the Aful Explorer, followed by the ISN H20, above the Lesthouer S08, Hidiz MP145 and MP143, Kefine Delci AE, etc.

I was going to recommend this as well. Mine isn't burned in yet but it's already impressive.

I hope you're right. Been waiting more than a week for a code. Purchased the ISN H20s in the meantime for $50 pre-tax. I'm definitely interested in the Fan3.

ISN H20 checks all the boxes. It's *super* impressive for its price at 70 USD (deep, fast, and musical bass; clean and detailed mids; engaging and pretty wide soundstage; good technicalities and more focus on the lower frequencies, but the treble is also nice). Not many people know about it since it's new. I would recommend it to anyone. Sorry if this sounds like an ad, but I am genuinely impressed by it, and you can get it [here](https://penonaudio.com/ISN-Audio-H20.html).

Just disclosing that I only have the ISN H20, which is the ISN below 100USD entry. So if you just want to try their sound that will not break the bank, you can try it. Recommendations for me to target as upgrade is the ISN H60 or the EBC80.

I got this a week ago and I love it. I think they have converted me to a loyal customer and I will only replace my H20 with another ISN. Love the tuning.
