I’m awaiting reviews of the new Fiio FT7. I am hoping they knocked it out the park like they did with the closed back Fiio FT1 which I love and own.

There are so many pairs now around the £500 mark. Top contender is still the Arya Stealth, but the Fosi i5 is £300 on Kickstarter (£500 RRP) seems like a good deal if it's any good. I watched 1 video so far in German and the only fault the reviewer had said is the headphone is not for bass heads as it doesn't have that kind of sound which sounds like it suits me. I like the food accent and also the large earcups.

Does the Fiio FT7 swivel?

Don't think the FT7 swivels. Z Reviews just posted a Fosi Audio i5 planar review and liked it a lot.

Just watched the review....A few things he said

"These are the biggest, warmest planars that has ever been, THE END.", "best planars under $1500." "Arya Organic has more detail but I am here for fun." and also he says it is better built than the Organic. He even said "this is better than every Hifiman headphone under $1,000".

He also keep comparing it to the Tungsten which says a lot.

Granted, it is just his opinion (using a product that was given to him) but even if it's half the price, it's worth it as the rrp is going to be about £500 and the Arya Stealth is £550.

So I've backed it! It sounds like a heck of a headphones for £330, with extra pad, which I think would come in useful.

In the time I watched his review, the number of backers has went from about 370 to 399.

Another review out, this time he has done measurements. I wonder the reason for the lack of the lower frequencies is because of those massive massive ear pads placing the drivers further away from the ear, and the attaching method of velcro.


I just picked it against Arya stealth and Fiio FT1

That’s a no from me. I am not liking that bass drop off. I have both the Stealth and FT1 so am very happy. It’s a good start though and competition is always good.

That is the only cavaet with this, but the drop off is similar to the HD600 except the HD 600 doesn't have that 80hz bump.

Personally I wouldn't be that bothered about the sub-bass drop off. If the HD 650/6XX has taught me anything it's that I'm not bothered about bass. However I know that subjective. The Fosi Audio i5 looks like it could be a real killer even when it lands into normal retail channels at it's £400-500 price. Good to see Fiio & Fosi launching some really exciting headphones out there.

The issue for me is that it is chonky; 550grams! Again says more about me and I am very much a gamer first than an audiophile, but those sort of weights are always going to deter me from this sort of headphone as much as costs I think.

For what i listen to, the drop off in those frequencies is not important to me, in fact, I dislike them so this is to my preference. By happenstance though, the Xduoo XA-02 has a "bass boost" button, so it might be a match in heaven?

We'll see, there is still like a month left before the Kickstarter finishes.

Could be. I suppose it depends how well they EQ. I don't really use EQ, but the iFi Zen Can Signature HD6XX edition I picked up secondhand has a very similar preset EQ for boosting sub-bass. So if EQ is available then then might help for those that need it.
 
That bass drop off is ridiculous for a planar, theres got to be a seal issue with the ear pads or something.

More likely just poor positioning during measuring - an air gap generally tends to increase bass in open backed planars as it increases the free movement of the diaphragm. A good example of this is the Abyss 1266 in which the ideal placement of the pads is slightly away from the ears creating maximum bass performance. The opposite is true with closed back planars though, they rely on having a sealed system otherwise bass response will be totally missing.

The tier that I backed comes with a spare pair of pads, but it is not the exact same pair. The one people have been using don't have holes.

Those holes might explain the sub bass drop off.

Yes that's what I like about it too, that screen looks amazing and I think I will just have to get one end of the month when it releases. I've asked them if I can get a review sample though first, no harm in trying lol.


Here it is in action:

Update on kickstarter for the i5.

Good that they are listening and tweaking I guess but I was Kinda happy with the review of it so far.

A Note on i5's Sound Tuning and Bass Response​


Fosi AudioCreator
May 7, 2025
Dear Backers,

We've received a lot of thoughtful feedback regarding the i5's frequency response, particularly regarding sub-bass roll-off. We would like to share the thinking behind our tuning approach.

The tuning of i5 was inspired by the immersive auditory experience created by classic Stax estats. We focused on achieving a highly stylized sound signature with excellent stage presence, particularly suited for genres like jazz and live recording of pop music. This is the concept behind our design of the mid-to-high frequency tones for i5.

In the low-frequency range, we incorporated some concepts from modern mixing and mastering techniques for handling bass. The i5 offers a flat response down to 80Hz, but deliberately holds back in the sub-bass region below 80Hz. This conscious decision was to preserve clarity while avoiding auditory fatigue in prolonged listening.

Our large, deep, and replaceable earpads not only improved wearing comfort but also significantly optimized pinna-related transfer function, contributing to the i5's super spacious soundstage. However, this design also made the reproduction of sub-bass to require much more diaphragm excursion, which explains the bass roll-off seen in the measurements.

However, we've also experimented with modifications such as covering vent holes on the diaphragm and sealing the connection part on the earpads, which result in noticeably deeper bass extension. If sub-bass performance is a high priority for some users, we are open to exploring tuning adjustments in the final production run to better meet your preferences.

All of these elements together shape the i5's unique sound identity, one that dares to depart from mainstream, homogenized tuning styles. We sincerely invite you to experience it for yourself, and just as sincerely, we welcome your criticisms and suggestions.

Thank you for your ongoing support and honest feedback!

The Fosi Audio Team
