Toneking T4 IEM

Not a full review, but just a few impressions. Very clean and clear mids and treble. Lean/neutral presentation that is somewhat bright. Treble is a little forward and detailed, but never sibilant or harsh. The midrange and treble are the stars of the show here. Bass quantity is below neutral. Very little sub bass response. Fast, BA bass. It can occasionally exhibit a little bit of a metallic timbre that is somewhat common with BA IEMs. It shows up more with some vocals and less with others. It's pretty noticeable in Can't Hide (feat. Ashe) - Whethan but not so much in White Foxes - Susanne Sundfør. Excellent pairing with iFi micro iDSD BL (w/ bass boost on). With the bass boost, these have a much more balanced signature across the board and they really come alive. Even with the boost, I'd say the bass is only a few dB above flat. Even with the boost, these are definitely NOT for bassheads or those who like a strong bass response. If the bass was like this out of the box, it'd be one of my top recommendations for neutral IEMs in the $100-$200 price range. The shape of the shells makes them quite comfortable for my ears and they are very stable. The cable is excellent. It looks great and is supple. Above average (low) microphonics. This is one of the best stock cables I've come across and I actually prefer it to the one that came with my 64 Audio A12t. It is a little on the short side. Travel case is protective and small; perfect for throwing into a backpack to travel or go to work/school with.

these are real detail monsters! Extremely clean smooth clear highs and mids BUT I found you NEED a good pure copper cable to bring the low end up . They have a definite character which makes them a winner or not depending on your preference. If details are your thing then they are amazing. They will however show up ANY issues with the recording, meaning with the highest quality recorded and mastered albums the T4's shine with a reference high/mids quality. Sometimes hiss is there but that is the trade off with such detail.
