BOGASING M4 Portable Bluetooth Speaker with 40W HD Surround Stereo Sound, Enhanced Bass, IPX7 Waterproof, Bluetooth 5.0 Wireless Dual Pairing, EQ, for Home, Shower, Outdoor, Beach, Party

Small & loud
This speaker is amazing for the price, it is compact and plays loud with great clarity. The Bluetooth has never let me down when connecting my phone. Use it to play Amazon music. I bought 2 of these and yes they sound just twice as good. Very easy to Bluetooth the speakers. Buy them you will not be disappointed. They certainly do not have any competition at this price, I have heard JBL, Bose & Sonus and can say this is better. I use them in my office, gym, house and camping. Charge last for about 12 hours and this let’s me use it all day. Well done Bogasing you have made an excellent product.

Hard to see buttons
Superb speaker except cant see buttons in dark which a assume every one does.simple fix paint liberally over buttons then wipe over.paint will remain in recess.perfect to see in dark now.

Bogasing vs Anker
I’ve owned the Anker soundcore mk1 & mk2 and was looking to upgrade to a mk3 but sadly the mk3 is Bluetooth only and doesn’t have an AUX jack, something I use with my laptop!!… after some deliberating I chose the Bogasing M4 which does have an AUX, plus a card slot & an EQ which the Anker does not!… whilst there’s nothing to complain about with the Anker the Bogasing is slightly bigger and fills the room quite remarkably with a powerful bass which is excellent for its size!!… its early days yet but I’ll certainly be advising my friends & family should they be looking to replace their portable speakers 🔊 to consider the Bogasing M4!!… 🤔

After 18 months the battery has died
Will now only work when connected to a power source. I’d recommend something by soundcore instead.Build quality was excellent and sound was amazing for it’s size but didn’t last. Will try for a replacement but doubt I’ll have any luck. Will update this review if I hear back.Edit: Amazon arranged a free return for a refund for me (exchange was not possible). I purchased a different make of speaker and hope that this is better.

I have two of these Bogasing M4 speakers. I use them TWS paired – for stereo. Here’s a few comments that might help others.Comparisons with Other Speakers:I can only compare these to my other battery bluetooth speakers: Bose Mini Soundlink and Marshall Kilburn II. When listening to one Bogasing (in Bass Mode – Green), it sounds comparable in sound to my Bose (but the Bogasing is 1/3 the price of the Bose) and plays louder (as it has more available power and the speaker is slightly larger than the Bose). When comparing it to my larger Marshall Kilburn II, the Marshall is more accurate in sound as the Marshall has the advantage of a much bigger box/drivers, more power, and precise EQ (bass/treble) adjustments – but again the Marshall costs 4x more than the Bogasing (so…if you are willing to pay more and have a larger speaker – the Marshall is great). Now, where the Bogasing really shines for me is when you purchase two of them and use the TWS feature (which my Bose and Marshall cannot do). I am truly impressed with the sound quality, loudness, and stereo field (much better volume and soundstage than using either a single Bose and/or single Marshall). I purchased the Bogasing units because I wanted something small/portable/stereo pair that plays loud, can be outside/weather resistant, and not distort. These Bogasing speakers do this perfectly for me.EQ Settings (VOCAL, BASE, 3D) Observations:VOCAL mode (White Light) – it is bright and the loudest position (as it removes a lot of the low end which frees power for louder mid/high frequencies). I only use the VOCAL mode when loud is the only required criteria. BASE mode (Green Light) sounds the most accurate to me but doesn’t play as loud as the two other EQ positions. I use BASE mode inside home. 3D mode (OFF light) seems to use the most DSP but has excellent extension of both base and vocals, is the 2nd loudest position, and does a great job of sounding full range yet not distorting. I prefer 3D mode outside.User Manual is Lacking some Info:The manual needs some help in the descriptions of the indicator lights – as the lights provide all kinds of helpful status but they are not described well nor indicated in the correct positions in the manual. There are 3 status lights: a combo PWR/BT/CHARGE (Blue/Blue Flash/Red) Light (which is above the “M” button on Left), there is TWS (Yellow) Light (also above the “M” button on Right), and a EQ (White/Green/Off) Light (above the EQ button). Having the power related status light above the “M” (Mode Switching button) instead of above the POWER button is confusing. Also, the TWS light location/function is not shown in the figures section of the manual – but TWS operation is described in the text.Use Issue (Red CHARGE Light Stays ON): **UPDATE**My Red CHARGE light never goes off (on one of my two speakers) after a full charge. The manual says its supposed to go OFF at charge completion (supposedly after 4 hours). It also states in manual that you should ensure you use a 2Amp supply/charger (not a smaller 1Amp supply) when charging. I am using a USB meter on my “suspect” speaker battery to track the charging volts/amps – and I’m finding that the final resting charge current is not dropping down as far on the suspect unit when compared to the charging values on the working unit. I believe that I may just have an out of spec battery in this particular suspect unit. I noticed some other reviewers on Amazon have indicated the same Red Light off issue, but I have not noticed as battery performance issues even with this light anomaly.**UPDATE** So…I have several in-wall receptacle USB power supplies and some external (brick) USB power supplies. All are 2Amp or higher output. For kicks, I took out my USB volt/current meter and checked ALL of the USB power supply output (V) voltages (with the speaker plugged in and charging). What I found was that the output voltage was not exactly the same across vendors (most were around 5.0V regulated but some went as high as 5.2V regulated – with newer units providing the higher voltage). What was interesting is that the RED Charge light FINALLY went out (i.e., charge completed) ONLY on the power supplies that were outputting above 5.10V (meaning this particular speaker charge profile/battery is very sensitive to the source power supply output voltage). You’d think the design should be such that it should work/complete charge with anything close to 5.0V/2A – but this was NOT the case for me. So…if you’re having issues where the speaker NEVER completes the charge cycle (i.e., light stays on). Then I’d suggest you try finding/using a USB power supply that leans towards the HIGHER side of 5V voltage output. Again, I may have a battery that is slightly out of spec, but other purchasers have mentioned/reported the same RED light issue. So hopefully the designers look at this data for potential improvement. Good Luck.Overall Summary:Excellent for the price!! Good sounding/loud speaker for its size. I really like the TWS mode.

Buscaba algo compacto pero con calidad de sonido y si cubre mis necesidades, super práctico su tamaño y bonito diseño y para su precio, excelente‼️👍👍. Muy recomendable🎼🎼
