”Practically flawless wireless earbuds.”- ‘Techradar’ – 5 Star review.

Work out without wires

With a Bluetooth connection to your smartphone or other music device, you can work out without wires. This leaves you free to exercise without the connection cable getting in the way. A 10-metre range from the source means your music device can be safely stored away or secured. A 10-hour rechargeable battery life is ample for the most intense sessions - even a marathon or two!

Work out without worry
Designed for durability, the BE Sport4 earphones are resistant to sweat and water (IPX5 rated) - making them the perfect partner whether they're used in the gym or out and about. Featuring revolutionary SpinFit TwinBlade ear tips, the BE Sport4 in-ears stay put where others fall out. They are uniquely designed to keep the earbuds securely in place during strenuous activity.

Change style, change colour
With a choice of green, yellow or grey ear wings, you can change the colour of your earphones to suit your style. Each colour comes in three sizes (as do the ear buds), meaning you can easily get the perfect fit for comfort and security.

Out in front for sound quality
The Optoma NuForce BE Sport 4 headphones also perform in the sound quality department. Supporting aptX and AAC files and making use of graphene-coated drivers, the BE Sport 4 in-ears give you the punchy and dynamic sound you need for maximum motivation.

Take the call
The high quality microphone fitted makes these headphones ideal for making calls. The inline remote also gives basic play, pause and track skip functions as well as the ability to use voice activated prompts – just ask Siri or Google Voice.

Get the headphone that keeps up without getting tangled up – the Optoma BE Sport 4.

Rated 5 out of 5 by from Great sound, and really easy to use. My first in ear bluetooth earphones. I've found them great, and easy to use.

Rated 5 out of 5 by from Great sound quality, even better battery life. Majorly impressed with the battery life on these. As someone who listens to 3 hours+ of podcasts a day while on the job, I can go around 3 days without having to charge these up, which is worlds longer than my last pair of bluetooth earphones that I had to charge every day. Sound quality is fantastic too. I can't comment too much on the build quality as I've only had them a few weeks but they feel super solid.

Rated 5 out of 5 by from Excellent gym headphones. Bought a pair of these on Chris from the Chamber street, Edinburgh location’s advice & have zero complaints. Great fidelity, quality battery life & a reasonable price. Service was excellent, no pressure to buy (ended up buying online as they were not in stock) but was given a great breakdown on my options. Very happy customer.

Rated 3 out of 5 by from Good sound, very poor Bluetooth range Sound is good, once you get the right fit in your ear. I bought them for running, as they are water proof. Bluetooth range however is terrible . I have had to change the arm I wear my phone on as the Bluetooth cuts out if I wear it on my left arm ( blue tooth module is in the right side of headphones )

Rated 5 out of 5 by from Battery for days... Litterally I was sent these headphones as a replacement to the Optoma NUFORCE BE SPORT3. which in itself is a testament to what a fantastic shop Richer Sounds is! If you look at reviews for these headphones, they struggle to find any benefit over the 3, to me, the differences are subtle and add to an already fantastic headphone. I listen to these quietly as i do a lot of on road sports, this week i have used these headphones on a 2 hour run, a commute. and a 4 hour run, without charging the battery still has plenty of life left!. the sound quality is great for such a small device. they're obviously sub par to over-ear headphones. but they're more than good enough for sports. The selections of ear tips and supports are fantastic, they even come in different hardnesses to ensure all ears are covered. If i were to pull up a point i did not like about these it would be the cable. but is is the same as all earphones like this. i personally find that the cable sometimes gets stuck in my neck crease, so that when i look over my shoulder it pulls on the ear buds. this can be sorted by putting the cable over the top of my ear which stops the cable from dropping to where it gets caught. I would have absolutely no hesitation suggesting these earphones to someone.

Rated 4 out of 5 by from growing on me each day Very light and comfortable, charges quickly and battery life is very good, blue tooth connected easily and it is generally very convenient and easy to use. Sound quality initially a bit light but that may be the quality of my rip off music files. Sensitive treble so noticing sounds not heard previously. Not a strong base. It doesn't bother me but any jostling of the cable causes interference and this may be intrusive if exercising. I use it while working and overall it is growing on me each day and I like it very much.

Rated 1 out of 5 by from Bad fit Bought these last week and have been really disappointed. None of the ear tips fit, and all of them are weirdly itchy. Even with the wins on I couldn't get a decent fit and everything just sounds empty, with zero bass unless I hold them in my ears. Obviously I understand that I can't return them but I would if I could as I'm very unhappy with them. Had high hopes after my Beats X died (a common problem - I would've got more as they were excellent otherwise) Not recommended

Rated 1 out of 5 by from Tried my best to like them but they are awful I can't understand how these get positive reviews. Firstly they don't sound anywhere near as good as my old cheap skullcandy,'s but worse than that the design is really poor. They keep pulling to on side because of the weight of the battery in the controller. The rubber has a rough finish so after a couple of minutes the left earpiece is being pulled out. I wish I could have changed them but didn't feel like I could take them back. Unfortunately the first really bad product I've bought from Richer Sounds.

Rated 5 out of 5 by from Great quality and sound I bought my earphones a few days ago. I really love them. It comes in a nice package. Richer Sounds provided a great delivery. I didn't want a truly wireless one, so it's perfect for me. You can easily choose your wings and you never lose your earphones. You can do a quick charge and it lasts for weeks. I'm very satisfied with the product.

Rated 5 out of 5 by from Great value for money earphones After getting advice from Richer Sounds Leeds, opted for these. I have been very impressed with the sound quality. They are perfect for using in the gym.

Rated 4 out of 5 by from Great battery life and good sound for the price. I bought the headphones as I am training for a 10k run and so far I think they are worth the money. They seem stable in the ear after finding the right fit, but there are plenty of buds and wings to chose from. My only improvement that I could suggest would be auto shutdown when they were attached around my neck using the magnet.

Date published: 2019-04-24
Rated 4 out of 5 by from OVERALL a good choice, not perfect..... I bought these to replace a pair of standard wired apple buds due to them falling out whilst running..... Audio quality : there's been a few occasions where I've been astounded how good these sound, having AptX on improves the quality slightly but connectivity is very hit and miss (losing my will to live with them on a commute to work, it was like listening to a jumpy CD almost constantly)...im guessing you could only practically use that mode of you werent leaving a room but anyway, I've found with AptX off, the sound quality and loudness is more than adequate.... Build quality: Very good, solid construction, no parts feel flimsy or cheap. Price: I got these at £75 and I think id pay up to £100 for them.... Fit: Right........ The buds and earhooks fit very well indeed, really good design.... HOWEVER.... The wire round the back of the neck (maybe because of the integral remote) causes this 'pulling' sensation on the earlobes (or in that area) which initially can be rather irritating, especially when you turn your head from side to side... And tightening the slack with the adjuster doesn't seem to improve things so I leave it relatively loose.... You do get used to it somewhat though..... Its not enough of a flaw to make me sell them put it that way...

Rated 4 out of 5 by from Simple to use in ear headphones Got these as replacements for the Sport3 s I got for Xmas which were damaged. Like the 4's a lot more. Very stable in the ear when you find the right combination of in ear shape for you. Good sound for a middle aged fella who like contemporary to classical. Works well outside too, I. Oortant for me as I spend soo much time outside. Would prefer to have more effective battery level indicator, as drops rapidly when it goes, but as it lasts me 10 hrs + of train journeys a week without a charge. V happy with them.

Rated 4 out of 5 by from Great sound; easy controls; impressive battery Bought a couple of months ago and I use them travelling to/from work as well as at the gym. I can usually get two or three days’ use out of the battery. The short charge (20 mins) feature is great too.

Rated 5 out of 5 by from Perfect gym headphones Bought these a few months ago and have been using them while at the gym. Sound isolation is incredible and blocks out practically all of the background noise. There are lots of different shapes and sizes of tips supplies so that you can find a good fit. Sound quality is very good for the price. Don’t go quite as loud as I’d like, but they are loud enough, and as the isolation is blocking out all the background noise this isn’t too much of an issue. Wireless connection is great, easy to pair and have only has issues with connection if I go a long way away from my phone. Would definitely recommend.

Rated 5 out of 5 by from Brilliant sound, perfect fit Have used theses in every workout this past couple of months, brilliant sound and blocks out completely the surrounding gym music and noise. Comes with lots of spare ear attachments very easy to find your best fit.google assistant works flawlessly so I don't have to use my phone to change tracks or artist. Would buy again and Wil upgrade if there is any new ones coming on the market in the future

Rated 2 out of 5 by from Not ideal Having read good for reviews for these, I was let down by the sound quality and volume - not strong.
Date published: 2019-03-11
Rated 5 out of 5 by from Excellent sound and don't fall out Recommended a set of these by Lloyd at Exeter store who is a gym goer, who has tried many wireless sets. These are definitely a bit fiddly to get the fitment right but plenty of options with supplied buds etc. For me, the bud with the in-line control is 'right side'. Ensure that the ear fitments point forward and are square to the speaker/battery housing. Choose a bud fitment for lug'ole size. Get all this the wrong way round and they will fall out, isolation will be terrible. Plenty loud enough and plenty bassy. Try Absence of light by Darko De Jean & Jean B. ONLY issue is that as it isn't true wireless, is that when sweaty the cable can grip your neck and you can just feel the pull sometimes when looking left to right, but I do have a 19 inch neck. Other than that, very pleased with them. Battery life lasts ages and mine work upto way over 10m in range across an office. Another set of wireless (Soundmagic BE10BT) that I own are commended as having great connectivity but my pair aren't - not even in my pocket. I think some of the bluetooth modules in headsets are a bit hit or miss and worth checking, on purchase. I own some Audeze Mobius wireless headset which also work ~10m well. You'll not get knowledge regarding AV and Hi-fi in any other national highstreet store like you do at Richer. Well done Exeter & Plymouth stores, both of which I use.

Rated 1 out of 5 by from Terrible bluetooth, Muddy, lack of bass DONT buy these! Having read some glowing reports ("near perfect") i hoped my purchase would be both useful and at least as good as the free earbuds that came with my phone. Sadly they are neither and i cannot recommend them at all. As mentioned in other reviews the bluetooth is very finicky with phone in pocket and regularly drops out or DCs completely. The ear seal is very hard to get right compared to other earbuds ive had and the result is no volume or bunch to the bottom end at all. Even with the right seal the sound really lacks punch and can get quite muddy even on high bitrate tracks. My free samsung wired earbuds are way WAY better, even after a 20 hr 'burn in'. Utterly disappointed i will absolutely seek a refund as not fit for purpose

Rated 5 out of 5 by from Quick Setup and Good Sound Quality Spend time getting the right in ear configuration for you, it makes all the difference to your experience. Quick and simple to set up on all Bluetooth devices. I’ve found the sound quality pretty good and battery life is outstanding for wireless earphones. Easy 10hrs use on a single charge (which takes 15mins for 2 hours and approximately 1hr and 30 mins for a full charge).

Rated 5 out of 5 by from Great sound and great battery life! The magnetic ends of the earphones really help and the battery life is awesome. Sound is balanced, a little more bass and they would be perfect. Coming from a bass head however
