JVC S40BT On Ear Bluetooth Wireless Foldable Headphones with Dynamic Deep Bass Boost - Black

Purchased for my partner.She needed something nice with good sound, not too bulky, decent battery life & most importantly fitting the head well while running & exercising .I was torn between this & some of many decent brands & models on sale here. Spent all my free time through a good few days reading review after review about each :DI have for many years now, a Sony & a JVC & a Philips set of wired headphones.In my opinion & taste the Sony is a nice sound with a just ok fit, the Philips is so so with a loose fit & with the JVC the bass stands out & it fits my head & ears the best of the three. So good that i could almost use them as ear muffs just to block out noise :)Reading reviews, there was one reviewer who actually mentioned that it was purchased for use while exercising & it fit well for the task without falling off or moving from the head. This plus my experience with the wired versions of these 3 brands helped me decide on this JVC here.Purchased the black one even though some color would be nice, but i don't quite like the way they designed the colored portion, could have had a nicer design i think.Very very pleased with the headphones.She has them now almost 2 weeks using everyday & absolutely loves them. We charged it up full when just arrived & since then the battery did not go down. Just did a fresh charge yesterday as she is off on a small family trip & travel.It takes around 2 hours to full charge.There was a good bit off confusion at the start as it refused to connect to any device, thought i has to send it back & not pleased about that at all.Seems this unit can only connect to one device at a time. When required to change to another device, one has to keep the on/off button pressed for 10 seconds till the light starts to rapidly flash red & blue. This is from the OFF state, so first turn off the phones (no light)Once flashing rapidly, link from the desired bluetooth device & away we go. Light turns blue & its all connected.The supplied manual was quite confusing & useless & i got this workaround info from a user on here who kindly put it up in his/her review. Credits go to that user so, many thanks u :)We have tried with 3 different android based phones, 1 android based tablet & 2 windows based laptops with bluetooth & all work fine.The sound is lovely such that i am considering getting one for myself too..but i'll try to resist till i would really need it.There is also a mic somewhere in the phones itself which we still haven't tried out, will do when she is back from travel.There are buttons for volume control. There is also the option of a stronger bass setting, this really depends on the type, quality & mastering of the music one is listening too. Nice to have it there for sure.To sum it up,Very very nice headphones here, can recommend.

Sound quality - 5/5Material - 5/5Aux - 4/5Comfortable - 3/5Design (not aesthetically) - 3/5The sound from these headphones is amazing. Hooked up with a well tunned equalizer they're just amazing. Deep Bass, Clear and Crisp Treble.They can also get pretty loud, I ended up using them at about 60% so I don't go deaf. They also have 3 built in EQ setups Flat - Bass - Clear.. I'm using Bass for music and Flat for movies.You can certainly tell that they're premium even just by touch. The plastic has a really nice feel to it, with sturdy buttons and smooth foldable joints.I mainly ordered the S70BT for their aux capability.. I wanted wide compatibility and ease of use in certain situations I came across before when I found myself with BT headphones but required 3.5mm to connect.. so I decided to take the problem out of the equation. As for sound quality over AUX, it's pretty bad compared to the wireless connection, and the built in controller doesn't work over AUX (don't know if this is too much to ask, don't mind it, but I think it should be mentioned).Improved sound quality over AUX using equalizers.As for comfort, after long use my ears feel uncomfortable, but I think that this has to do with the poor design.Now, when I say poor design, I don't mean aesthetically, it's more of a scale issue (for me at least).. I noticed that if I press the headphones against my ears, just gently, the sound improves.. A LOT!.. Now this is where I think the design flaw comes in.. It's obviously a lack of isolation, but I honestly feel like the headband is too long and the speakers sit lower that they should on my ears.. I used to stretch it on all the other headphones I used.. For this one I feel like I need to tighten it. I guess that what I'm trying to say is, don't buy these if you've got a small head?.. :)) Definitely not for kids anyway.. Now I don't want to suggest that the headphones are bad, this is just me, and this might not apply to everyone..My Conclusion: I really like the sound quality and I doubt I can get it from any other headphones in this price range, so I won't be returning them just because they feel a bit oversized. Recommend!

This is my third pair of JVC Headphones over a 5 year period, so I feel able to give a good overview on these headphones.I brought my first pair back in 2015 as I needed some wireless headphones due to some hospital stays. I am autistic so needed something to block out the majority of sound, be easy to use, yet stylish and wearable for long periods of time. Over the last half a decade, I have used these headphones, everyday for hours at a time. They have become a huge part of my identity and are very comfortable.The sound quality is good and easy to control from the actual headphones. They are extremely easy to set up and connect to a range of devices.The design is sleek and comfortable to wear, it may be a little tight against your head at first but this goes over time. They last very long and I charge them daily. These do scratch very easily (see photos) but I am not too bothered about this.Colour options are limited and I have only ever had black pairs - however these are nearly £10 MORE just for the black colour which is a huge downside. Although I am only on my third pair in 5 years, its caused by the charging bock breaking off making it not charge over time.Overall would highly recommend.

I purchased these headphones based on one reviewers advice that you would have to have a pea-sized head to wear them. Well I do have a pea-sized head and thought ‘at last….a pair of headphones that won’t fall off!’ and promptly put them in my basket. They are rather small so beware. Excellent for people with child-sized heads though and the sound quality is very good. Lightweight and you can barely hear the outside world when wearing them. Great for the price.

Great product.
