Rated 1 out of 5 by from Almost Impossible to wear them properly The TwistLock technology that is used in these headphones may be great in theory but there's no included instructions on how to use it. So, they are too large than a "normal" in-ear headphone to fit inside the ear, and they just drop out of the ear (even with the small enhancer). Additionally, the perceived sound quality is very low as a consequence of not fitting correctly. On top of that there are no clear L/R markings. They are there, but hidden... under the bit that goes behind the ear (the earloop). So unless you take them off, you won't know which is Right and Left. But this is the least. I found some online videos on how to fit headphones with TwistLock technology. However, these refer to similar products, with different enhancers or no earloops, and they are not adequate.

Rated 1 out of 5 by from Why not to buy the headphones I bought these a week ago and when using them for the first time they seemed really good as they didn't move about while running however one day while running the part of the earphone where it goes behind your ear fell out and got lost, now the headphone isn't useless as it doesn't do its job anymore

Rated 2 out of 5 by from Comes apart too ez The behind the ear pieces come off way to easy. They need to be a tighter fit. I have almost lost them twice in only 4 uses. Looks like I will be adding some glue to hold them together rather than risk loosing parts.

Rated 1 out of 5 by from Tiens bien mais son médiocre Acheté il y a quelques heures, son tendant trop vers les basses et presque rien dans les aigues donc plutôt médiocre sur ce point et en général plutôt mauvais mais bonne basses si c'est ce que vous voulez entendre. Clair dans les appels, bouton ne sert QUE pour les appels ! (Attention à ceux qui penseraient que cela coupe et reprend la musique comme tous les autres écouteurs celui là ne le fait pas). Deux oreillettes incluses en différentes tailles (2) mais ne change que le tour dans l'oreille (pas le petit capuchon que vous mettez dans l'oreille comme les intra)

Rated 4 out of 5 by from Good for the value These were exactly as I expected from a comfort and sound quality perspective. My only feedback is that the over the ear piece does come off easily and I have almost lost one of them 3 times. You need to be especially aware of this if you take one bud out and leave it around your neck or tucked into your shirt. Also be aware that the music control does not control the volume (a small detail that I missed in the specs).

Rated 5 out of 5 by from Super confort pour un super son ! Acheté pour profiter d'un bon de réduction, reçu quelques jours plus tard par colis (Livraison rapide, colis conforme). Pas facile de trouver le truc au début pour les mettre facilement, mais une fois cette difficulté passée : écouteurs super-agréables, super son, et surtout qui ne bougent pas, bien calés sur mes oreilles.

bonjour, peut on commander le volume avec ces écouteurs ? Le kit mains libres semble pouvoir changer de piste, mais qu'en est-il du volume ? (j'imagine que oui, mais je voudrais être sûr). Merci pour votre réponse.

Asked by: benoitpe
Le kit mains libres ne permet que de répondre à un appel. Il ne change pas de piste (essais sur 3 téléphones aucun ne réagit). Il ne commande pas le volume.

Are these wired or wireless?

Asked by: jon carpenter
The FOCUS 300 are wired headphones. If you are looking for wireless headphones, I would recommend to take a look at the INSPIRE 500 or FOCUS 500 headphones.

Hi, Thank you for your question. Sadly, neither the JBL Focus 300, or any other (sports)headphone we have in our current product catalogue are suitable for swimming with. If you have any other questions, please feel free to contact us on customer.support@harman.com
