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 analyses reviews to verify trustworthiness.
Bluetooth latency is excellent for video games when paired with an Aptx-LL adapter.
Bass boost mode is clean and provides good rumble. No glaring issues with sound. Upper mids/lower treble is prominent in comparison to some K612s which makes vocals more treble-centric or 'clear', similar to SHP9500s. No issues with sibilance.
Comfort is not amazing due to its edged shape. I suspect using custom tips from 3d scanning would make these extremely comfortable. One of my ears experienced irritation with the hook styled wiring so I just leave it dangling. My ideal earbud positioning soundwise makes the outside edges of the earbud dig into the cartilage which also makes it a little tender.
A rounded shape would've made these much more comfortable.
These came with 2 sets of cables one set for straight out music and the other set for my iPhone 8 plus in a very nice and professional looking case. I am very happy with the sound took a little getting use to as I had not used this type of headset before but well worth the money I spent on them...
I have been using the M6 pro and the adapter for quite a number of months now. I got it as a replacement to the version 1, which the audio quality are good, but on calls it is not so good. I have been told that on a call my voice is muffled (on both versions) and couldn't hear what I was saying - I have to put the mic next to my mouth during a call before the caller can hear me. If you use the strap to tighten the cables to the back of your ear, the callers cannot hear you unfortunately.
Bought these as an alternative to Shure SE 215 and was really impressed. Sound quality is great. Slightly too crisp on the highs when used with the silicon tips but by no means harsh. When used with the Comply foam tips (included) this is fully sorted and also tightens up the low end to the point where I personally think they are just about spot on, particularly for the price. Not as bass heavy as some of the alternatives out there but still plenty three and well controlled which suits my taste well.
When used as IEMs on stage the mids are really clear and punchy cutting though really nicely. Isolation is perhaps not quite as good as SE215s but not far off and perfectly usable.
Package comes with a really nice case with space for extras and both sets of detachable cables included in the purchase price. Cable is good quality and the 'memory' cable portion holds shape well when shaped to your ear.
Overall these are a really comfortable pair of IEMs with solid sound quality and a fantastic price for what you get.
I bought these as a direct replacement for the M6 PRO 1st Generation and the difference is noticable: - The low frequency is much improved - The highs are less tiny (helped too by the lows) - The cable is thicker (good and bad but will be tougher) - The 3.5mm angled plug is much stonger
I've bought so many pairs of in ears I've lost count. Straight out the box these sound great - and certainly better than their price tag may suggest. Fit is a little weird to get used to - I had to try most of the tips to find what suited me best. The fact they come with 2 cables is great - one with a mic, one without. And you can upgrade them to bluetooth as well, which is genius. Sound is detailed without being too real to listen to all day. Bass is nicely controlled. No harsh treble, mid-range is great too. Honestly, for the price, I can't fault these. I have more expensive over ear cans, but in ears for me are for the bike, gym, around town... I actually found myself wearing these around the house whilst tidying last night they sound that good. I rarely write reviews, but if you're fussy like me, try these.
I'm writing a mature review, after constant use for more than 6 months. I have to say the audio quality is more than good for this pair of headphones/monitors. They don't sound too absurd, all frequencies seem pretty balanced, which is good. I don't like that they tend to overdrive/distort a bit when above a certain volume, even with the best audio files.
That said, they are not noise cancelling headphones, but the included eartips help a lot to dampen the sound and for the most part they do a good job. Pretty decent choice also for the eartips sizes and such. Great.
Comfort wise, definitely to improve. Don't really like them. Though for this price you would get something like Beyerdynamics or Sennheiser that do not last as long since they don't have the same cable system so used on monitors.
I purchased this to use with my cell phone. I currently own a set of Sennheiser CX300II's but it doesn't have a mic. You get a generous set of accessories which adds a lot of value. It comes with two sets of cables. One with and one without a mic. The cables are stiffer, thicker and more tangle resistant than the CX300II's and one would presume more durable. It comes with 6 set's of silicone tips and one Comply memory foam tip, plus a 1/8 to 1/4 inch adapter and a large case. The large case is necessary because the stiff memory wire adds a lot of bulk to the earpiece.
The ergonomics are a little bit weird with the memory wire. I watched the YouTube video before attempting to set mine up. This for me is both a plus and a minus. On the plus side, once it is setup it is very comfortable and stable and makes sense since these monitors were designed for musicians on stage. On the downside, they are more fiddly, to put on/take off and are bulkier, requiring a big IEM case.
In terms of sound, the M6 is mostly balanced. I find it has strong deep bass, similar to the CX300II's, while not exactly flat, is fun to listen to. As with all earphones, you MUST get a proper seal; otherwise, the sound will be tinny and thin. I didn't find the treble quite as detailed or emphasized as the CX300II's, but it wasn't objectionable either. Individual vocals came across strong, but multipart harmonies tended to bleed together and, didn't have the clarity and separation I know is there. To be fair, the detail's I'm talking about I hear through my full sized planer magnetic headphones which are in a different league altogether; however, I'm just talking about the resolving power of the M6II's against CD quality Flac files which for testing, I used my Emotiva Stealth DC-1 Dac/Headphone amp instead of my cell phone. Comparing them to the slightly less expensive CX300II's, the Sennheiser has a slight edge with slightly better treble, separation and vocal detail. As a side note, these things are not as efficient as the CX300II's and require more volume if that is important to you.
So why the five stars? For $65 CDN, you are getting a great sounding IEM with a lot of value. In terms of overall sound quality, they are slightly less detailed in highs and midrange than the CX300II's, which was the price/performance leader a while back, but I believe they are discontinued now. The cords are removable/replaceable, which is relatively rare in this price bracket. If you damage the cord on the Sennheiser, you must replace the entire earphone...which brings us to the Lifetime Replacement Program. If you ever damage or lose your M6 beyond the warranty period, you can get a replacement pair at half price from Mee Audio. Although I've not used this yet, people who are hard on their equipment may find this beneficial.
Update 9/26/2018: I'm not a big believer in burn in, but after 50 hours as recommended by the manufacturer, the sound has opened up and there is an audible improvement. The vocals have increased detail and separation. I now rate the M6 slightly better than the CX300II. I prefer the vocals and the bass which is deeper and tighter. The CX300II's have slightly more treble, the bass is strong but sounds bloomy in comparison.
