NuForce BE Sport4 Premium Wireless Sport Earphones with 10h Battery, Sweat Proof, AAC + aptX, Quick Charge and with Graphene Drivers

Not worth the money, feels more like a £20 - £30 product.Sound quality is a mixture of muddy low ends and sharp and shrill high ends. Just not refined or handled well at all.The connection is constant, but there are digital artifacts throughout which is really distracting. I tried the earbuds on 5 different products (Apple, Android, Windows), all with the same issue.Cable is very very cheap, thin, noisey. as are the plastics use over the product.The remote is heavy and tugs, feels cheap.The voice use to inform you of command is hilarious and of poor quality, sounds like it was recorded in a bath.Carry case also feels like a cheap China ProductFor close to £90 I'd expect way more.Best avoid and look elsewhere.

I have spent the past 6 months delving into the World of bluetooth headphones/earphones with very mixed results. I bought these after becoming frustrated with my Jaybird X3's falling out during vigorous workouts and they offer the BEST FIT. No matter how much I move (think kettlebell swings, jogging, weightlifting) and sweat these do not budge, the battery also lasts much longer than the Jaybirds which is a massive bonus. Now, for me the sound quality of the Optomas isn't as good as the X3s - I can only describe them as sounding a bit narrow e.g. the soundstage isn't as big and you can't hear as much detail BUT when working out do you really listen that closely? They also offer good noise isolation, so are great when the gym is busy. For me, the secure fit + magnetic heads and better battery life are more important than sound so I 100% recommend these earphones.

UPDATE (February 2020):Had these for about 18 months now and the left ear has completely stopped working out of the blue. It’s a shame as I’m now out of the 1-year warranty period and I don’t use these every day. At most, five times a week for 1-2 hours for gym sessions only.In terms of audio quality and comfort, I really did enjoy these but extremely hesitant on purchasing another pair if they don’t last for more than 2 years. Although other well-known brands might not have the same audio quality I'm looking for, value for money would be better given the support and alternative options when buying from a better known brand.I’ve emailed both the company and the seller and have been informed that nothing can be done once they’re out of the warranty period which is understandable but a shame that they have stopped working when the warranty expired!————————————————I bought these specifically to use for the gym. Overall, the sound quality is actually really good for the price you’re paying in comparison to other brands. I would highly recommend these to anyone who doesn’t want to fork out for a new pair of headphones just for gym but would still prefer a good quality product that delivers good sound and decent sound isolation.On a day-to-day basis I use Bose in-ear, sound isolating headphones which of course are renowned for their quality. In comparison, the NuForce headphones deliver a clear sound with a good smooth bass which isn’t too overpowering or tinny. I did need to adjust the EQ on my device to get the sound I was looking for whereas I don’t need to do this with Bose. Initially, the sound is a little bit of a compromise if you are used to using more expensive headphones but once you are used to the sound, it’s actually ok.The ear buds do a great job of isolating outside noise. Especially in a gym environment where they’re already playing their own loud music. Although, I still don’t feel they fit/sit well on my ears like my Bose in-ear buds. I feel that I have to constantly check they’re not falling out and they do feel a little loose even after trying the various sizes that are provided.The only downsides I could pick out:a) Setup - the instructions were not clear. Just a bunch of pictures. It probably actually takes 4 seconds to turn them on with the power button as opposed to the 2 seconds described on the manual.b) Connection - although they connect perfectly easily to any device (I have so far only used them with an iPhone 6s and an iPod Touch) for some reason the connection crackles and starts to jump a few minutes in. Whether it’s playing a song or watching something on any of these devices. It surely can’t be my devices as I regularly connect Bluetooth speakers with them and they never have this issue.c) Charger cable - it’s a little tough to remove the charger. The connector is quite stiff so I did have to tug at it quite harshly form the charing port on the headphones which worries me a little as I didn’t want to damage the headphones on my first use.Overall, the charge lasts a while. The range is really good. And they are definitely a game changer for gym workouts! I just wish the sound wouldn’t crackle when I’m in the zone! It can be a little off-putting.

A little disappointed since these headphones were featured in a review for the new OnePlus Bullet 2 headphones, which I was thinking of upgrading to. They are cheaper, but not as good as the OB1s I currently use.Good enough to keep at work for general use, but not great. Reasons :Sound quality - not bad, but not amazing. Required quite a bit of tweaking of my phone's equalizer to get enough base.Comfort - out of the box, really itchy on the insides of my ears. Not comfortable. I matched the earbud rubber things to the size of my existing headphones, but they felt very "full" in my ears. Perhaps intentional.Aesthetic - ok, but quite large. I hate reviews where people complain about the look of things. You can see them in the picture, but these were genuinely bigger than I expected.Reception - awful. My phone loses connection to these dudes when in my trouser pocket. My OnePlus bullets connect happily from two plasterboard-separated rooms away...Battery life - impressive. I have not yet charged these since I got them a week ago. This is ideal for work... I can just let them charge at the weekend!Overall then, not too bad. Meh. These things are always subjective and they will "do the job". Are they better than others. Hope this is considered a fair review.

I’ve owned a lot of headphones and I’m really into Home Audio, so I did quite a lot of research when I stupidly broke my gym headphones/buds. I stopped on these after the generally decent reviews and I’m really happy I did.The 1st impression is of quality. Metal buds with very good magnets to keep them together, really good choice of silicone attachments for all ears (mine fit the ones on there), a nice little bag to put them in (a must to keep headphones a while).The sound quality is really good. Nice and clear on a wide variety of music. Decent through the sound range, including a good bass kick. Voice is also really clear: I listen to a lot of podcasts and audio books.They are good in terms of being usable in the gym. Sweat doesn’t change the sound or make them fall out as some less well designed ones do, although I have a very good seal with the standard fitments in the box (including the little silicon ‘wing’ keeping them in my ear nicely).Battery so far is good and proves the claims made by the manufacturer.I’ve a pair of B&W P5 Wireless and whilst these don’t quite match, they’re not as far off as expected. For the price, a huge bargain.I think they will last a while, but will obviously test this out. Very happy with the purchase.
