When I first got my DM7 I was very impressed by the sound. I felt it was a risk buying from Linsoul UK knowing the DM7 would be coming from China, but they arrived within 7 days and boy were they great, and then bam. the left side went, I am sure I heard a pop and the bass just dropped out. Sending back was not a great experience. I had to pay for return postage, and had to return for a repair. Linsoul did cover the postage once the DM7 arrived. But I got them through Linsoul UK and after some searching realised that under Amazon UK policy, they should have covered return cost before I sent back, and, although this is a difficult position, once I had notified Linsoul UK of the problem they should have offered a full refund or a replacement, without requesting me to send back the DM7, the reason being Linsoul UK is in UK and I should not have had to send back to China, being that as far as Amazon UK are concerned the DM7 came from a UK company.
I would like to purchase the Tin P1 but they too come via Linsoul UK and it does appear that Linsoul UK are not fully aware of Amazon policy and as such I am really unsure if I want to take the risk again, given that Linsoul has suggested that it could take a month for a repair/replacement DM7 to arrive, and that does not include how long it will take for the repair/replacement to be delivered. As much as I liked the DM7 with the problems I have had I am thinking of pushing for a refund and up grading my FiiO FH5 to FH7.
