My Teclast T-39's sound sucks now after one month of use. The bass is easily distorted and all the other sound effects like Stone 3d/equalizer and RBS just adds to the distortion. Even with the equalizer set at flat, the sound distorts when volume is at 20 and above.

I used Sennheiser PX-100, AKG K-26P, JBL 220 and all headphones have distorted bass when plugged into my T-39.

My Meizu M6 and Sony NWZ-S610 are way, way beyond T-39 in terms of sound quality. Meizu and Sony are stellar performers.

Another gripe I have with T-39 is the very poor video quality. Even at the highest quality setting using AVICh. Ver. 4, the colors are washed out, very limited viewing angle as in directly perpendicular to the screen and a lot of pixelation.

I just don't know if I have a lemon but I have lost confidence with Teclast. These players are only good on paper but are poorly executed design-wise.

T-39 is my last Teclast purchase ever!

something might be wrong with your headphone jack

problem is that the tianjiao engineerst must to set the limiter in T39, i don't know why but right now it's off! you have to set your EQ to "-" (especially StoneEQ)

Mine was also sounding awful because I was trying to use many EQ settings at the same time. Then I followed the advice of another member and turned everything off except for the Stone EQ.

Effect = Nor
Custom EQ = Flat
RBS Effect = Flat
Stone 3D = Off

Then adjust the Stone EQ frequencies the way you like. Even then, I can still get distortion where my Cowon F1 would be fine.

Also the headphone socket is very tight and is damaging (wearing away) the tip of the connector on my Sennheiser's

The probelm is the Wolfson chip that Teclast utilizes. A lot of members in this forum seem impress with Wolfson. I AM NOT.

I have both C280 and T39 and both use Wolfson as a DAC and both sound horrible and distorted when you adjust the parametric equalizers. You cannot extend the bass because sound then distorts quickly.

No wonder, Apple dropped Wolfson because the Ipod models that had them sounded bad as well.

Now Toshiba made the same mistake in their S series when they used Wolfson WM8978. Read the reviews at anythingbutipod.com and you will find that the S-series is by far the worst sounding of all Toshiba MP3 models.

I recently bought a Toshiba U-202 model and I learned that Toshiba designed the Sigma-Delta 1-bit DAC chip inhouse and implemented that in this model as well as in their T-400 series. Now the U-series is one of the cleanest sounding MP3s I have. I must say it rivals my Sony NWZ-S610. There is an almost perfect tonal balance. Another thing is I tweaked the parametric equalizer and even at the highest bass settings, the sound is never distorted but instead had warm bass.

Forget the hype about Wolfson. Their chips are among the worst sounding out there.

Don't spend your hard earned money on Teclast because the trusted Japanese brands, Toshiba and Sony have come down in prices and are FAR SUPERIOR in Sound Quality.

If you don't trust what I say, test them out at Walmart or Circuit City.

My Samsung P2 uses a Wolfson DAC, can't remember which, but it rivals my ESI Juli@ ---> PPA ---> Audio Technica A900 desktop setup, which costs roughly $600 altogether.

@minusflo: just play with the EQ
