Great in-ears
Disclaimer: I bought these solely to use as in-ear monitors during live music performances, and not for listening to music. I’m sure they are great for listening to music, but if that’s what you’re interested in, then this is probably not the review you want to read.I was initially skeptical of these earbuds because of their low price-point compared to some of the major competitors (Shure, Sennheiser, etc). However, I just used these during a gig for the first time the other week and they were great!My setup was using a Roland V-Drum electronic drum kit, with a monitor mix running directly into the drum controller. The sound in the BASN earbuds was crystal clear, and did a very nice job of suppressing most of the external sound in a loud room. Not noise canceling necessarily, but not too far off either. Because the earbuds did such a good job and minimizing external noise, I didn’t have to crank them up super loud. Having primarily used traditional wedge speakers for my entire live music performance career, I could definitely tell a huge difference at the end of the night, when my ears were NOT ringing!Because I could hear myself, and the rest of the band, much more clearly than I’m used to, I felt like I was able to play more relaxed and didn’t wear myself out as much as I normally do after a few hours of drumming.The earbuds were very comfortable. They stayed in pretty well, even once I began to sweat. I adjusted them 1 or 2 times during the performance, but nothing major.If there is a downside with these earbuds, it’s that the suppression of external noise makes it more difficult to verbally communicate with the rest of the band during a performance. If you play in a band that likes to use verbal cues as a way to communicate during performances (which I often do), these earbuds could make that more difficult. However, the tradeoffs are well worth it.Final verdict: Great in-ears at an amazing price.

Includes lots of accessories
UPDATE (Aug 2021)I used these monitors while playing bass for a church set, running through an Ampeg SVT running through the line out into an X32 mixer. Here are my updated impressions.I think these are great as in-ear monitors for stage use, particularly for musicians in the rhythm section (bass, drums, maybe guitar). The bass and mids of these earphones makes it easy to lock in with the groove. The very tame and smooth treble makes it that the cymbals are never too harsh in my in-ear mix. My bass sounded really clear through the headphones with no noticeable distortion. I ended up switching back to the included silicone tips from third party foam tips and the fit for me was very comfortable.Contrary to the “BSinger” name, these are not my first choice for monitoring as a singer. I think this is more personal preference. These earphones have very even mids but for singing I would prefer a gentle bump at 2kHz. For comparison, in my home studio I use the Audio Technica M30x earphones and they have the gentle 2kHz bump that I prefer for singing. Other singers may have no issues.Fir reference M30x earphones are very flat up to 1kHz, with a gentle boost at 2kHz, a big cut at 5kHz, and another gentle boost at 10kHz. In comparison these Basns seem to have a gentle bass bump at 400hz and below, very flat mids, and smooth treble roll off.While the bass is boosted a bit, it is not as aggressive amd punchy as earphones marketed to audiophiles. Audiophiles may want to look elsewhere for earphones that have massive bass and treble.Original review———These headphones are very beautifully packaged, well above what I would expect for the price. The included accessories are everything you would need: regular TRS cable, TRRS cable with built in microphone for calls, FIVE pairs of earned tips, lapel clip, and 1/4 adapter. It also comes with a carrying case.Comfort: they feel great. With 5 pairs of tips you can probably the right size for your ears. However, i ended up buying an extra set of memory foam tips to use with these headphones.Sound: Bass is prominent. Treble is clear without being harsh. The one thing to mention is that these headphones sound a little weak in the 2-4 kHz range, compared to my other headphones. As a result, for music listening, vocals sit a little further back in the mix. This frequency response makes the headphones sound great for listening to instrumental music, but wouldnt be my first choice for vocal-centric music.Use: I think the best use for these headphones are for professional stage monitoring. The good bass and mids make it easy to hear the instruments in the rhythm section, and if the vocals aren’t coming through enough, that is easily fixed with some EQ and leveling on the mixer.Overall these have a lot of value for the price and are great for stage musicians on a budget.

Professional head piece
It’s awesome! The sound is crystal clear, volume control is good, good design.

Passt und hat eine super Klangwiedergabe, die mich als Schlagzeuger voll überzeugt.

These EMI headphones are ABSOLUTELY worth their price. They are lightweight, easy to wear and fit really well in my ears. I stream with these everyday now and can hear every detail. After 8 hours of wearing them they still feel comfortable.For just listening to music these are not bad. There is a little loss of detail in the mid range but for most ppl enjoying casual music listening these are a great buy. And if you want another colour of cable, there are many for sale.I really like these earphones
