The Leo has a simple unboxing experience typical of budget sets, with no case included and a basic cable. It’s lightweight, comfortable, and offers decent isolation.. 

The ND Leo is a budget-friendly IEM designed for both gaming and music enjoyment, with a stronger focus on the latter. 

The bass on the Leo is quick and delivers solid impact, but it’s more prominent in the midbass region than the subbass. That’s not to say the subbass is weak—it’s just not overly emphasized. The midrange has a decent body but can sound slightly recessed on rock and metal tracks. Overall, the mids are warm and smooth. The treble is very open and airy but it’s not the most natural sounding at times. 

This IEM works well as an all-rounder, and I think it’s great for people looking for something casual and affordable to take out. That said, it’s a nicely made set with a solid enjoyment-to-price ratio.

The Surfans M10 Crystal IEM features a hybrid setup with 1 dynamic driver and 1 balanced armature, delivering rich bass and clear treble. Its nano composite diaphragm offers fast, accurate, and distortion-free HiFi sound, while the 9.2mm dual-magnetic driver produces powerful bass and vivid detail. A precision resonator chamber ensures a natural, spacious soundstage with crystal clarity. The single-crystal copper cable with silver plating enhances resolution and provides ultra-clean signal transfer. With a transparent PC shell and aluminum faceplate, it’s lightweight, durable, and visually striking. The detachable 0.78mm 2-pin connector allows easy upgrades and a secure fit, and the coaxial braided design is shielded for noise-free, accurate audio.

I found the M10 to have a good light build quality and comfort as well as isolation were above average. The provided case was large and could fit the IEM and a dongle or small player perfectly. The cable was decent but was the weakest part of the presentation. 

Sound quality of the M10 is very enjoyable.

I found the Bass well done with enough depth and texture to convey the energy drum solo in Chocolate chip trip by Tool. The Bass is elevated but still sounds very natural and with good speed and decay. The midrange is lush with rich vocals and excellent note weight although there is a little brightness in the upper Mids the star here is Male vocals and warm lower Mids.  The treble is sparkly and has very good air and a comfortable limit to the extension. Soundstage is wide , accurate and would be great for games and music alike. 

This is a well-done IEM from a company that knows sound, It is a warm rich and somewhat musical IEM. 

The CD40 is a straightforward player made from durable black plastic. In the box, you get a test CD with nature sounds, a USB-A to USB-C charging cable, an aux cable, and a manual. I love that it includes an SD/TF slot, making it feel a bit like a DAP as well!

The retro top-loading design is super convenient — just pop open the lid, put in one of my CDs and the music starts within seconds. No complicated menus, no waiting. I especially appreciate that it runs on both battery and USB-C power. The built-in 1000 mAh battery easily lasts five to seven hours, perfect for longer listening sessions, and at home I simply charge it via USB, which is really practical.

The sound quality is very good. Through headphones and in-ear-monitors, it’s clear and has nicely balanced, with crisp highs and a well-controlled bass. Even older recordings sound pleasantly natural. It also connects easily to speakers or a stereo system via the 3.5 mm jack, with no unwanted background noise.

I also love how easy it is to operate. The buttons are large, responsive, and have a satisfying click — all function, no gimmicks. It plays CDs, CD-Rs, CD-RWs, and MP3 files, so I can enjoy even the discs I’ve burned myself. Every format I tried worked great.

In a nutshell:
The Greadio CD player perfectly blends retro charm with modern tech, delivering reliable, clear, and effortless music playback. I would have liked Bluetooth and a Bass boost as well but for the cost its very good.
