In your review, give a preamble so that others can see a baseline of what your individual preferences are.
EG - here was mine for the BA100:
Preamble - 'about me'. (This is to give any readers a baseline for interpreting the review).
I'm a 46 year old music lover. I don't say audiophile - just love my music. Over the last couple of years, I have slowly changed from cheaper listening set-ups to my current mid-fi set-up. I vary my listening from portable (i-devices) to my desk-top's set-up (PC > coax > NFB-12 > LD MKIV > HP). My main headphones at the time of writing are the Shure SRH1840, Senn HD600, AKG K702, Shure SRH840 and Shure SE535 Ltd Ed. IEMs. I have auditioned quite a few entry and mid-tier cans, but have yet to hear/own any flagships other than the SRH1840 (at current time of writing this review).
I have very eclectic music tastes listening to a variety from classical/opera and jazz to grunge and hard-rock. I listen to a lot of blues, jazz, folk music, classic rock, and alternative rock. I am particularly fond of female vocals. I tend toward cans that are relatively neutral/balanced - with a slight emphasis on the mid-range. I am neither a bass or treble head (you could argue that I do like clarity though). Current amps = NFB12 and LD MKIV. I also formerly owned several portable amps - the most notable being an Arrow 4G and GoVibe PortaTube.
For the purposes of this review - I used the HSA BA100 straight from the headphone out socket of both my iPhone 4 and iPod Touch G4. I did not bother with amping them, as IMO they do not require an amp – and the likelihood is that HiSound have targeted them toward an audience who may not use additional amping anyway. By now I have probably notched up around 30-40 hours listening on the BA100. In that time I have noticed no change to the overall sonic presentation (I do not believe in 'night and day' burn-in). I will allow that the more time I've have spent with these IEM's, the better they continue to sound to me. Personally I think this is brain burn in - but I will respect others choice if they interpret this as physical burn-in.
This is a purely subjective review - my gear, my ears, and my experience. Please take it all with a grain of salt - especially if it does not match your own experience.
It just gives everyone an idea of any personal preferences which may influence your own subjective experience.
And try to list both strengths and weaknesses as best you can.
