Thank you for all your honesty and opinions. I hope you enjoy the new Sonic even more than the previous version and feel confident to make a switch as a Soul rider. Big shoutout to Our Kite Life for putting in the effort. 🤙

I own a15 Soul for years and was on a testival in Norddeich/ Germany. Tested the 15 and 18 Sonic4. I can acknowledge the points in the Video, like a Soul on Steroids. Hangtime unbelievable, easy handling. Only a Little Bit slower due to the aspect Ratio. Hab i to choose, I‘d take the Sonic now. Formula1 drivable for the average kiter.

[@SurfmanCHK]

Afterword:I ordered a Sonic4 18m today…

[@neildahl1188]

I enjoy your videos. I am a LEI foil kiter. I have not yet got into the foil kites, but now like the sonic4 reviews in your video. Glad to see you are back.

[@petebang]

Nice video!!! But hej, for every Foil Kite you have to adjust the mixer according to your riding style. One setting I can share to counter wing folding is, only for the Speed 5/ Sonic 2, : B-1 cm, C-2cm. We tested it in Sri Lanka..9/12/15 sqm speed5 in 20-30 knots. The kites became much more stable.

[@olivierhamon3828]

Just tried the Sonic 4 12m , and in comparison to my sonic 3 13m (I also previously own a soul v1 12m), it really feels more stable, specialy the wing tips as mention in the review, it turns quicker which was a bit disturbing at the beginning. the most important point, as an hydrofoil big air lover, I feel it boosts higher may be due to this quicker turn Overall, looks like it has win more from the soul behaviour than it lost from the sonic 3 peformances which make a perfect combo for easily boosting

[@tubelesskite]

Nice review and good editing as always , many thanks !

[@deeearnshaw9551]

Thank you for helping me decide- I just got to try out my new Sonic 4 18m to replace my Soul v1 18m and your review pretty much matched what I felt- couldn’t believe the hangtime increase over the Soul and how much easier it is to steer while boosting. The upwind performance was a pleasant surprise too.

[@aleshaborisovich]

The colours and design of these colours is beautiful! Looking forward to the Soul 3 , 15m in a similar colour beauty ❤

[@robboerman9378]

Thanks for the review. I do feel the sonic 3 gets a bit bad rep on being non-user-friendly. It does require some understanding how to fly it but I find it to be incredibly stable once you do.

[@collegepros]

Thanks! Love your reviews and appreciate everyone’s opinion!

[@OurKiteLife]

Thanks, glad you enjoy them!

[@arminharich3779]

thank you, for your review. I agree on all. I noticed, that is can jump higher with it that the Sonic 3. I can swing it harder up without loosing the edge. What are your experience about jumping hard?

[@olyvine]

This is such a useful video! I have so many people asking me about the sonic4 and there’s so much objective info here 😊 makes it easier to advise what to chose! After all it’s worth more than some cars 😅

[@abacaxifamily]

On the spot! First review of sonic 4 right after release 👍🏽

[@AvengerIl]

I really enjoyed the Sonic2Rs.. I found Sonic3 a little too user friendly, should have gone for VMG I guess? Lot of people like user friendly kites should have just gone for Souls or Inflatables? I was hoping Sonic4 would go the other way... More spicy, more AR

[@manfredanderson2080]

Great honest review with wonderful editing. Soul on Steroids! My next kite must be a sonic 4!

[@victorojeda109]

Blessed recovery ! Just watched your how a Foil works video. Fantastic ! I have a suggestion for a new video about “how energy is transferred from the Kite or Wing through us ( human mast) to the board. This energy passing through us must be wonderful … since we have a huge smile every time ! Best regards

[@krzysztofsmyla3769]

I had the opportunity to compare the sonic 4 and soul 2, both 8m2 for fouling. I can confirm all your observations. In addition I'd say it driffts way better. The sonic I got was RTF with race bar and I must say that tandem is the dream. Sonic in my opinion drifts also better, although it has slimmer shape, keeps it riding downwind, but still having bit of race "soul" stay responsive and dewelops fast power when needed.If I find a buyer for my soul2 I will go for the way faster turning sonic 4. Thank you for your review

[@wallaceanjinho]

Very nice review 👏🏼👏🏼👏🏼🤙🏼

[@alanlysne7423]

Great review as always. Chuck with the relaunch!

[@OurKiteLife]

I wish there was more wind for Chuck so he could of tried proper boosting. Also it was waist deep so he kept hitting the bottom :(

[@ChuckTatham]

@@OurKiteLife really interested to know what the boosting is like! Thanks for including me in the test.

[@ChuckTatham]

not too hard when you can stand up :-) It was pretty darn light though.

[@Kirmo13]

Summer is coming 🤩

[@abacaxifamily]

I’m missing the comparison of the kite sizes of Sonic3 to 4. Does the 12m sonic4 match the power of the 11m sonic3 ? 13m vs. 15m / 9m vs. 10m ?

[@jameskelly714]

Great review. Any news on pricing vs S3? The biggest excitement for me is I might be able to pick up a well priced S3

[@OurKiteLife]

not yet sorry

[@robinungerer1345]

What is the difference between the 10 and 12 m? Would you recommend one over the other (like 10 soul was „better / more loved“ then 12 m)? I fly sonix 3 11 and 18 m, and want to switch my small 11, bot dont know to with sice🤷‍♂️ 🙏 thank you

[@OurKiteLife]

So far we have only tried the 10m so can’t comment on differences between the sizes. Hopefully someone who has can chime in.

[@equilibristik]

Hi, hope your Ankle recovered well. Did you already had the chance to Test the Hybrid and how it is doing on an Directional ? All the best, Daniel

[@OurKiteLife]

Hey Daniel, I haven’t tried the Hybrid yet - sorry!

[@Gorops]

Can You clear some things out? Who is its intended target audience and use? What is the sonic good for and whats the better use case for soul? Additionally i have a question. As I live close to a lake and far from the sea I rarely get to kite as the wind speed is considerably lower than at sea. What kite could i buy to reliably try twintip kitesurfing in 8-12 knots with gusty mainland conditions? I weigh around 90kg. Thanks for info.

[@OurKiteLife]

Sonic4 is for someone who knows how to fly foil kites and looking for high performance and big air. Better use case for soul is someone looking for an all round kite or who is new to foil kites. For your scenario I’d go with the soul (handles gusts better) in a larger size - 18 or 21m

[@juanpasala]

What about angles whils going upwind? speed for course racing?

[@OurKiteLife]

angles for upwind felt similar to Sonic3. Haven't done course racing

[@benmaz]

I’ll be doing a side by side test for course racing with the Sonic 3 as soon as I receive the 4

[@bennettian]

Hi, super vidéo, I am getting 'good' with my foil, I like very light wind. What kite should I go for for extra light wind, any advice ? I am thinking Soul 18 with 21m lines ? (I am 85kg, front foil 1100cm2, my light wind setup today is Soul 12m with 25m lines, this is enought to take off even in 5-6 knts with a loop , but some times not enough to keep on going.

[@OurKiteLife]

18m would definitely work in those ultralight conditions, however it is much slower to turn and the range may be limited. I’d probably lean toward the 15 personally, but if you can demo both that would be the way to go

[@Johan_Pentrose]

Terrific. When did you shoot this video. We’ll be there for a week and i see you guys are in wetsuits at Salvo……thanks. Looks like the wash will be great for a few days in a few days.~vincent

[@OurKiteLife]

We were in Salvo for the last week of April and first week of May. Hope you have a great trip!

[@Johan_Pentrose]

@@OurKiteLife Thank you! I got an efoil so really getting the hang of foiling in general and your love of fkysurfer has me sold. we will be at Hatteras village just down from Sandy Bay and the wind looks ideal for the next week. Sorry to miss seeing you and your crew there like a year ago! Always watching you guys! Get well see on the water!

[@aleshaborisovich]

Hello! You tried Soul2 and Sonic 4, with which kite would you get more power in low winds of the same size?

[@OurKiteLife]

Comparing soul2 10m to sonic4 10m, the sonic has a little more power in lower winds

[@aleshaborisovich]

@@OurKiteLife Thanks 👍

[@aleshaborisovich]

Hi, I have another question. Does Soul2 10m have a little bit more power in kite loops than Sonic 4, 10m?

[@thomaschristensen8991]

Hope new videos will come soon

[@Valentins_fantastic_World]

Hello, which harness model on 10:44 is it?

[@ChuckTatham]

@valentin Mrx It's a Dynabar XT bar with "U" bolt setup on a Dakine Vega harness. Interesting catch :-)

[@Valentins_fantastic_World]

@@ChuckTatham Thanks for info. I use seat harness too.

[@Jonpilo-uz1yf]

Which size of sonic 4 have more boosting, faster riding in below 20knots? 10m or 12m?

[@OurKiteLife]

It would depend on the wind speed. We’ve only flown the 10m so can’t comment on the 12

[@Jonpilo-uz1yf]

@@OurKiteLife okay, thanks for info

[@CroLarus]

...hope everything is OK and you can continue with kiting and video's...

[@Electric-fatbike]

Disappointed that the Sonic 4 has a lower AR. I was hoping for a higher AR. First kite that FS has not put the technical info for the kite on the website. It seems like the canopy might be thicker than the Sonic 3 which will create more drag. Nice review.

[@abacaxifamily]

I’d say, if you are looking for higher aspect, you should go for the VMG. Canopy of sonic3 is 44g/32g, Sonic 4 got 44g/34g So upper and lower sail is more durable

[@darsmy5702]

Do you think that it drifts better than the Soul 2 ?

[@OurKiteLife]

Soul would drift better due to its aspect ratio

[@shaa197]

Hello from Siberia! Maybe this kite is better than the previous ones because it's a new kite? 😁

[@ChuckTatham]

this is always a factor....fresh tuned kite. A well tuned Sonic 3 is well behaved too. :-)

[@abacaxifamily]

Yes and no, it depends what your preferences are. S3 is a good kite no question , S4 is different but better in a few points only.

[@henryle3283]

I’m in Texas, USA where can I buy sonic 4?

[@OurKiteLife]

Flysurfer has their dealers on their website: flysurfer.com/fs-partner/

[@davidbeach7399]

Hey, how is the ankle recovering? Are you not making videos anymore?

[@OurKiteLife]

Ankle is almost back to normal. We are planning to publish more videos in 2024 :)

[@ThomasTune82]

what about depower? the sonics were race kites.. so there was not as much depower like on the souls..

[@jurgi1103]

The range of the sonic4 is bigger than on the soul2.

[@krash2094]

Where can I order a Sonic 4 from ? Also do you guys have a special promo code by chance ?

[@OurKiteLife]

Here are Flysurfer dealers: flysurfer.com/fs-partner/ Sorry, no discount code!

[@krash2094]

@@OurKiteLife Thanks 👍 and which bar do you recommend for the sonic for free-ride twintip ?

[@OurKiteLife]

Sorry just saw this! We recommend the FS Infinity bar

[@franckr2275]

In a nut shell buy the sonic it is better !!!!!!

[@querlyfan2502]

It seems a bit like a updated speed 5
