Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.

- Reviewed in the United States on May 21, 2025Color: A, RedVerified PurchaseVery comfortable and functional. Excellent warranty service from otium as well
- Reviewed in the United States on January 25, 2023Color: A, RedVerified PurchaseYou'd never guess by looking at me, but I go to the gym nearly every day. For the past year I'd been using Shockz OpenRun bone conduction headphone for the gym as I like to listen to music and YT videos while working out, but I also like being able to hear around me in case anyone wants to compliment my sweet azz. (For the record: this hasn't happened yet, but it might, and I need to be prepared.)
The problem is, in the past 12 months I've been through two pair of the OpenRun headphones. The first set stopped taking a charge and wouldn't turn on the first time it got cold here in Colorado and the second pair worked flawlessly until the rubberized exterior wore out at the control buttons. I didn't want to spend $150 again for the same thing so started looking around for other options.
I'd been planning on using an older pair of SoundCore over the ear headphones that were broken, but serviceable, when Amazon showed me these Optium. The SoundCore's didn't have an IPX rating and most of the reviews said they didn't last long under stressful usage, so I was excited to see these not only having an IPX rating of 7 but also their price tag (I purchased them for $20)
I bought them hoping they would suffice, and they came the next day. I have worn them to the gym a few times now and I can honestly say they're perfectly fine (for the price). Do they have amazing sound quality? No. I can hear the music and videos without worrying about them falling off my head, though. Do they have bass because we're all about that bass, right? Not really, no. But, then again, neither did the Shockz. In fact, my Amazon Echo 2 buds have more bass (and ANC) than these. At the gym, that doesn't matter to me since there's lots of clinking and clanking anyway. Plus, no ANC, which means I can hear around me when someone wants to whistle at my legs. Don't get me wrong, these aren't "tinny"' they're just bass-less, so, more treble. Kind of like my truck speakers ... but that's another story.
The IPX7 rating also means I don't have to worry too much about them when I'm in the steam room or sitting in the spa. I don't swim or shower with them, though.
The charge lasts far longer than either my OpenRuns or my Echo 2s, but these have significantly less features to drain the battery away.
Earlier today I took a call while listening to music through these and the other end said I sounded fine, so that's a plus.
These Optiums came with a small case, some ear pieces to adjust to your ears and a small clip you can use to clip the wire to your collar or headband, if you're that guy (don't be that guy).
For $20 I couldn't be happier with a headset. I would have given these 4.5 stars, if allowed, as opposed to 5 if they had any sort of bass.
- Reviewed in the United States on March 6, 2025Color: A, RedVerified PurchaseI’m writing this 3 years after the fact. These are cheap headphones but you get a bang for your buck. I bought these in the summer of 2022. I’ve also bought headphones from a competitor that looks exactly the same.
The competitors on Amazon fell apart within a year, however I’m still using these ones 3 years after purchase. I only use these for the gym, EVERY DAY, through sweat and abuse yet the base and sound in both buds are just as good as when i bought them.
In no way am I really taking care of these things so it’s just a testament to the quality of these “cheap” headphones.
It’s $20, take the dive. I’m sure you’ll like them.
Currently in process of buying my second one as a backup.
- Reviewed in the United States on April 23, 2025Color: B, BlackVerified PurchaseI've pressed two sets of there's headphones.. the first was the better of the two by a long shot. The newest set is very low volume when everything on my phone or laptop and the headset are turned all the way up. Kicking myself that I lost the older pair that used a micro USB charging cable ..( the new set used USB-C cable)
- Reviewed in the United States on March 29, 2025Color: A, RedVerified PurchaseGreat headphones. I purchased them for my fiance who's a garbage man, plays softball and do his side jobs while listening to muaic and these headphones are awesome. Hes had them since christmas 2023 and they still keep a full charge for 2 days for him and when they do get low it only takes 30 minutes to charge. Awesome headphones 10/10 would buy them again.
A nice big plus is that they have a type C Charger
- Reviewed in the United States on January 10, 2019Color: A, RedVerified PurchaseI am not an audiophile. I can't imagine shelling out $100+ on nice headphones. I have an $8 pair of wired Panasonic earbuds that I think are great (minus the annoying cord) -- and indeed, those are my baseline for comparison purposes with the Otium headphones.
The Otium headphones are inferior to my $8 earbuds in every possible way except for the fact that they do not have a cord that gets tangled as easily. The noise that comes out of them is flat and lacks richness. It has plenty of bass -- especially if you turn the volume up -- but it's like they had a meeting and said, "If we crank the bass, nobody will notice the otherwise-terrible sound quality!" I was listening to new music and hated all of it because of the quality issues and the small, nearly-imperceptible skips in the playback (I'm on a hardwired fiber connection; it isn't my internet). To say that these earbuds play "music" is like calling pasta sauce smeared on a saltine cracker "pizza." And again, this is from someone who thinks $8 earbuds are great.
And let's just say I got a defective model, and they don't all sound this bad (I think they all sound this bad; mine sounded bad but not "holy cow this is defective!" bad): these are SUPER UNCOMFORTABLE. The only adjustment you can make to the fit is by changing out the rubber tips. That's better than nothing, but since the over-ear piece is entirely non-adjustable, all the weight (and relatively speaking, it is a lot of weight) sits on your inner ears. I don't think I could wear these for more than an hour or two before I'd have to take a break from them. I also find myself wishing there was a joint between the "ball" of the earbud and the bulkier, outer-ear piece, which might make it easier to get a better fit.
The good: they came with few extra sets of rubber tips in different sizes, a nice case, a little cord-keeper (to help take up some of the slack in the cord between the ear pieces), and they were packaged in a cardboard box instead of a plastic clamshell (thank you!)
**UPDATE**
The seller contacted me in response to this review to offer to send me a new pair of headphones because I found the first ones so unsatisfactory. They did not ask me to change my review, which I appreciate. I'm not taking them up on the second pair because regardless of sound quality, I don't think they'll be any more comfortable than the first pair, but I appreciate their effort to resolve the issue and have left feedback saying as much on their seller page.
**UPDATE UPDATE**
The seller contacted me again (a year later?) in response to this review, offering me a $15 gift card to delete my review. To quote: "As a small business your experience is important to our success,we would be pleasured to give you a gift card worth $15 if you delete your review. And would you mind telling us your order number and amazon email? So that we could send the gift card to you as soon as possible?" This is super shady and I feel like you all should know that they're manipulating their reviews.
**UPDATE UPDATE UPDATE**
The seller contacted me AGAIN (what are we up to now, 15 months later? I write this in March 2020) with the same offer as the first time. They've passed my comments onto their R&D team and want to send me a new pair. As I stated a year ago: I don't want a new pair. These wireless headphones are not for me. I know you guys are reading this. Please stop e-mailing me about this. My review stands.

1.0 out of 5 stars Cheats . They are dumping bad quality product in India
Color: B, BlackVerified PurchaseVery disappointed with the battery backup.
I bought this same earphones of the same company when I was in the US and it turned out to be really great, having a great battery life which unfortunately I lost.
I came back in India recently, needed an earphone for running, was glad to find this same earphone on Amazon India and so I bought it. Only after a couple of uses I found and realized this is nothing like the one I bought in the US. Its battery backup drains after using for just couple of hours. They claim it's battery life is 8 hours which is not even near of the actual battery life of 2 hours.
They are charging almost same amount of money in the US but there we get a good performing product but here, in India it seems they are cheating people .
