5.0 out of 5 stars Absolutely Muvellous!!!🥳🥳👍🏽👍🏽🤩🤩

S. · 23 December 2022

Hi Fellow Boloians,The questions you need to ask yourself first are:Do you need a wireless charging case? Do you need a companion app?Do you need regular firmware updates?If the answer is "No" then you're on your way to possibly owning the best and most pure anc earbuds on the market.The buds simply work! Lovely design, great build quality, gorgeous sound, superb passive and active noise cancelling.As for the comfort, these are without doubt, the most comfortable earbuds I've ever owned!!! The first I've been able to lie on side without any discomfort. Superb work from the design team 👍🏽🙌🏾I got the Kef's for £149.99 and as of 23/12, they are this same price. They do fluctuate between £149.99 and £199.99. Considering some of the poor expensive choices out there, at £149.99 they are outstanding value!So, in my subjective opinion, the Kef Mu3's are superb and well worth your money, time and music.I also own the technics Eah-az60's which simply offer EVERYTHING I could ask for from premium anc earbuds. If the Kef's aren't you bag then give the technics a look in 👍🏽👍🏽Hope this little review helps and Merry Christmas one and all! 🎄 🙏

5.0 out of 5 stars Biased but still...

First off, I am a great fan of Kef loudspeakers. This is a personal comment, but isn't everything about sound reproduction to do with personal likes and dislikes.I find these earphones are comfortable with great sound. Once burned in, the quality just improves. Comfort is important to me and many, and these do not disappoint in any way or shape. I am confident that these could be in use all day.My only question is in connection with the sound cancellation. I cannot, with my ear, to discern the difference. Perhaps my use is limited and does not allow for a true comparison.

4.0 out of 5 stars Good earbuds quality built, but the maximum volume not good.

Good earbuds quality built, good brand name, sound quality is good enough but the maximum volume not good and some other features not available compared to the high price your are paying.

5.0 out of 5 stars Superb sound.

These earbuds and case look and feel quality, very smooth feel to the hi gloss finish, paired with my phone first time and reconnect instantly, I’m no audiophile but, comparing these to my Bose soundsport I prefer these, really clear and punchy I can here sounds I can’t with the Bose, ANC works just fine but I can’t really tell the different between the three modes if I’m honest, they are really comfortable to wear when you find the right fitting tips and lightweight, haven’t used for calls yet. Would I buy these again, yes absolutely.

2.0 out of 5 stars Poor quality and unreliable

G. · 28 July 2024

I bought these for Christmas in 2022, at first I was pleased with the sound amd quality, a few months later, one of the earbuds stopped working, so I contacted Kef to report the problem, I was asked to return them for repair although they were only a few months old and still under guarantee, I was told I had to pay the postage??, after a couple of weeks I phoned customer services to ask if they had been repaired, I was shocked with attitude of the customer service person, when she told me it was my fault for putting different tips on them, but they had resolved the issue, and if I wanted them back I had to pay £10 for the return postage which I did. Just over 12 months since I bought them I had another problem because no matter how much I turned the volume up you could hardly hear anything at all.I phoned Kef up again to report the fault, and I was told they were our of guarantee and I would not only have to pay postage both ways I would be charged with the repairs even though we're only 2 weeks out of guarantee, again customer services were not very friendly or helpful.I have earbuds I have had for years and never had any problems with them.I decided to not to return them and just put the cost of them down to a bad experience.It's a shame because initially I liked them with ease of use, but the altitude of Kef put me off.

5.0 out of 5 stars Wonderful Kef Sound

G. · 28 January 2023

Wonderful Kef sound but portable, long battery life very comfortable and the noise cancelling is not detectable over the music, tried quite a few different headphones but these are the best yet by a long way.

5.0 out of 5 stars Sound as it should be

D.W. · 27 April 2023

I’ve tried many different earbuds sone costing nearly twice the price of the Kef mu3 but none can match the natural sound that these offer, I’m very particular with what I use to listen to my music with and these are definitely here to stay.

4.0 out of 5 stars I agree with other reviews

Perfect but it’s not loud enough but I recommend it

Klanglich absolute Spitzenklasse – audiophil und ausgewogen

H.S. · 5 August 2025

Klanglich für einen In-Ear Kopfhörer wirklich beeindruckend!Was sofort auffällt: Der Bass ist schnell, trocken und extrem gut kontrolliert. Es gibt kein nerviges Wummern, sondern einen klaren, präzisen Tiefton, der Musik kraftvoll unterstützt, ohne sich in den Vordergrund zu drängen.Die Mitten klingen sehr natürlich und ausgewogen. Gesang wirkt absolut authentisch, fast schon greifbar – egal ob ich Klassik oder moderne Popproduktionen höre. Es fühlt sich einfach richtig an, nicht überbetont, aber auch nicht flach.Auch in den Höhen liefern die Mu3 genau das, was ich mir von hochwertigen In-Ears wünsche: Sie sind klar und fein aufgelöst, ohne dabei zu zischen oder scharf zu werden. Das macht das längere Hören sehr angenehm und ermüdungsfrei.Was mich besonders überrascht hat, ist die Räumlichkeit. Für In-Ears bauen die Mu3 eine wirklich gute Bühne auf – man hat das Gefühl, die Musik lebt im Raum, statt nur im Kopf. Das ist in dieser Bauform längst nicht selbstverständlich.Das Noise Cancelling ist solide – nicht ganz auf dem Niveau von Sony oder Bose, aber absolut alltagstauglich. Für mich steht aber der Klang klar im Vordergrund, und da spielen die Mu3 ganz oben mit.Unterm Strich: Wer Wert auf exzellenten, präzisen Klang mit audiophilem Charakter legt, sollte sich die KEF Mu3 unbedingt anhören. Sie sind nicht nur für Klassik oder Jazz geeignet, sondern liefern auch bei Pop und elektronischer Musik ein extrem stimmiges Klangbild. In Sachen Soundqualität brauchen sie sich nicht einmal hinter deutlich teureren In-Ears von Sennheiser & Co. zu verstecken.

Excellent son, super autonomie, connexion facile mais ANC discrète et confort discutable

M. · 19 February 2022

Le son est vraiment très bon quoiqu'un peu plat (neutre) mais c'est la signature KEF, ne vous attendez pas à un son dynamique ou basseux.L'autonomie est intéressante, près de 8h à volume 3/4.Il n'existe pas d'appli mais la connexion est facile, même lorsqu'il s'agit de passer d'un appareil à un autre (les écouteurs ne sont pas multipoints).En revanche, la réduction de bruit est assez nulle...heureusement qu'il y a une bonne isolation passive, sinon l'ANC serait quasi inexistante.Enfin, le confort n'est pas terrible. Les écouteurs ne conviennent pas aux grands conduits auditifs. Même avec les plus gros embouts, ça nage un peu dans mes oreilles. Et si vous vous achetez des embouts plus grands, sachez que vous aurez un peu de mal à fermer le boîtier de recharge (mais ça se fait).Je suis assez déçu et vais les renvoyer.

Einfach gut

Robuste, klangvolle und langlebige Kopfhörer. Einfach gut zum weiterempfehlen 👍

Kendi Sınıfının en iyisi

Ç.Ç. · 5 May 2023

yurt dışı incelemelere bakanlar zaten kendi tarzında en iyisi olduğu görecektir. KEF stereo hoparlör konusunda ne kadar başarılı olduğunu duymuşsunuzdur. Ufacık hoparlörler harikalar yaratan bir firma. Kulak içi kulaklık konusunda da kalitesinden ödün vermemiş. Eğer amacınız kaliteli müzik dinlemekse bu fiyat aralığından kesinlikle tavsiye ederim, ANC si ve Mikrofon kalitesi Sony ve diğer rakip firmanın ürünlerinden biraz arkada kalabiliyor ama müziğin doğallığı konusunda KEF in yanına bile yaklaşamıyorlar.

正解の音はここにあった

S. · 30 May 2025

テクニクスAZ100,80、ゼンハイザーTW3、有線ではSureSE846などを使っています。AZもゼンハイザーも、低域強調の不自然さが気になり、イコライジングで調整して使ってきましたが、たまたまKEF Mu3のレビューを読んで購入してみました。これが正解の音だったんだな、と納得のいくイヤホンです。非常にバランスが良い。低域から中・高域まで隙が無い。すべての音が正確な場所で、埋もれず、広がりをもって耳に届く。しかもモニターライクではない。素晴らしい音楽鑑賞空間を提供してくれます。首都圏朝通勤時に2，3度、一瞬接続が途切れました。またノイキャン外音遮断性は低いです。が、その弱点を打ち消すだけの音の良さがあるので、ちょっとテクニクスやゼンハイザーに戻る事はあり得ないと思います。良いオーディオ機器なので、出来るだけ音量を上げて、音場に浸る事をお薦めします。
